Small tubes. Garbage cat. The factory piece is holding back power that you're already making. Whether you're running a Type R or a Type S or pushing the Accord or the RDX or the TLX you're dealing with the same problem. RV6 spent a whole racing season testing and revising before they released this downpipe because they wanted it right. The downpipe is where exhaust gets freed up. You've got a turbo motor making solid power in stock form but if you want more the downpipe's gotta flow. RV6 ditched the small tubes and the restrictive cat and went bigger. 300 cell high temperature cat. Larger diameter tubing. The transition's smooth so exhaust doesn't fight itself. You're getting better scavenging. You're getting lower backpressure. You're getting real power gains. And here's the crazy part. The new downpipe is actually less bulky than stock but it still bolts up like factory. They 3D scanned the engine bay and designed this in CAD to fit perfect. The factory heat shield stays on. It bolts to your factory exhaust or any aftermarket parts you've got. No custom fabrication. No headaches.\u003c\/p\u003e\n\n\u003ch4\u003eHere's Why The Stock Downpipe's Holding You Back\u003c\/h4\u003e\n\n\u003cp\u003eThe factory downpipe on your turbo is small tubing. The cat's way too restrictive. Your turbo's spinning and pushing air but it's fighting backpressure trying to get the exhaust out. The engine's not breathing right. You're making less power than the motor's capable of because the downpipe won't get out of its own way. The RV6 downpipe fixes that. Bigger tubes mean air flows without getting choked. The 300 cell cat flows way better than stock. The stainless transition is smooth so there's no turbulence screwing things up. Exhaust moves. The engine breathes. Power shows up.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt To Last - Not Some Cheap Knockoff\u003c\/h4\u003e\n\n\u003cp\u003eThis downpipe is full 304 stainless steel. Everything. The flanges. The cast transition. The cat. The outlet. The heat shield mounts. All stainless. RV6 didn't cut corners just because it's hidden in the engine bay. Every weld is TIG welded and then argon back gassed to clean out all the junk and make sure the welds don't fail. We've seen people buy cheap downpipes and they start leaking at the welds after a year. The flanges crack. The heat shield rusts. The whole thing becomes a nightmare. Don't do that. The RV6 downpipe is built solid.\u003c\/p\u003e\n\n\u003ch4\u003e3D Scanned And Designed Right - Perfect Fit\u003c\/h4\u003e\n\n\u003cp\u003eRV6 used 3D laser scanning and CAD to design this. They scanned the actual engine bay so they knew exactly what they were working with. The transition from turbo to tube was designed so exhaust flows smooth without fighting back. You're not getting a downpipe that kinda fits and you're hoping it works. This one fits perfect. The factory heat shield mounting points stay there so nothing's getting improvised. It bolts on like it came from Honda. Because it's engineered to fit your car exactly.\u003c\/p\u003e\n\n\u003ch4\u003eOne Downpipe - Seven Different Cars\u003c\/h4\u003e\n\n\u003cp\u003eRV6 engineered this to work on the FK8 Civic Type R. It's compatible with the FL5 Civic Type R. It's compatible with the DE5 Integra Type S. It's compatible with the 2.0T Accord. It's compatible with the RDX. It's compatible with the TLX. So whether you're boosting a Type R or a Type S or pushing the Accord or the RDX or the TLX you've got the downpipe. One piece works across all the platforms because they all have turbo engines that need the same thing. Same turbo. Same exhaust path. Same restrictions. Same solution.\u003c\/p\u003e\n\n\u003ch4\u003eReal Power Gains - Not Just Marketing Talk\u003c\/h4\u003e\n\n\u003cp\u003eYou're getting a noticeable bump in horsepower and torque with this downpipe. How much depends on what else you've done. Stock turbo car with just this downpipe. You're looking at 15-25 hp depending on the car. Already got a tune and an intake. You're still gaining real power but the exact number depends on your full setup. Either way you're getting the turbo to spool faster. The exhaust flows clean. The engine pulls harder. You feel the difference when you drive. We've seen people put this downpipe on and immediately notice sharper response. The turbo spins up quicker. The car feels alive. That's what happens when you free up the exhaust.\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eRV6 Performance high temperature catted downpipe\u003c\/li\u003e\n  \u003cli\u003eFits 2017-2021 Honda Civic Type R FK8\u003c\/li\u003e\n  \u003cli\u003eFits 2021 Honda Civic Type R Limited Edition FK8\u003c\/li\u003e\n  \u003cli\u003eFits 2023-2026 Honda Civic Type R FL5\u003c\/li\u003e\n  \u003cli\u003eFits 2024-2026 Acura Integra Type S DE5\u003c\/li\u003e\n  \u003cli\u003eFits 2018-2022 Honda Accord 2.0T CV1\/CV2\u003c\/li\u003e\n  \u003cli\u003eFits 2019+ Acura RDX\u003c\/li\u003e\n  \u003cli\u003eFits 2021+ Acura TLX\u003c\/li\u003e\n  \u003cli\u003e300 cell high temperature cat\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel throughout\u003c\/li\u003e\n  \u003cli\u003eLarger diameter tubing than stock\u003c\/li\u003e\n  \u003cli\u003eSmooth stainless transition\u003c\/li\u003e\n  \u003cli\u003eTIG welded and argon back gassed\u003c\/li\u003e\n  \u003cli\u003eFactory fitment retained\u003c\/li\u003e\n  \u003cli\u003eFactory heat shield and mounting points retained\u003c\/li\u003e\n  \u003cli\u003e3D scanned and CAD designed\u003c\/li\u003e\n  \u003cli\u003e3 chromoly exhaust studs\u003c\/li\u003e\n  \u003cli\u003e3 locking nuts\u003c\/li\u003e\n  \u003cli\u003eGraphite gasket with sealing ring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003e2017-2021 Honda Civic Type R FK8\u003c\/li\u003e\n  \u003cli\u003e2021 Honda Civic Type R Limited Edition FK8\u003c\/li\u003e\n  \u003cli\u003e2023-2026 Honda Civic Type R FL5\u003c\/li\u003e\n  \u003cli\u003e2024-2026 Acura Integra Type S DE5\u003c\/li\u003e\n  \u003cli\u003e2018-2022 Honda Accord 2.0T CV1\/CV2\u003c\/li\u003e\n  \u003cli\u003e2019+ Acura RDX\u003c\/li\u003e\n  \u003cli\u003e2021+ Acura TLX\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e RV6 Performance high temperature catted downpipe for turbo Honda and Acura cars.

The wide cast inlet blends turbine outlet and wastegate flow instead of smashing them together, and the cast outlet tapers smoothly into your front pipe. That is exactly what you want for 2022 Civic turbo efficiency and real Acura Integra exhaust improvement, not just more noise.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eExpect more flow across the whole powerband, less backpressure, and cooler exhaust gas temps, especially once you turn the boost up. Two Step back purges the welds on site for heat tolerance and long term durability. Just be straight with yourself, if you coat it, wrap it, or insulate it and it cracks later, that is on you and it is not covered. The downpipe includes gaskets and stainless hardware, and it carries a 24 month warranty that covers welding.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eIf you are shopping a Civic 2022 high flow downpipe, an Integra aftermarket downpipe, or you want Integra catalytic converter performance without going full race pipe, this is a solid answer. It is the Integra high efficiency downpipe we keep recommending because it works on stock cars and it scales with mods. SKU: TSP-DWN-01-02. Also yes, people call it the Two Step Civic downpipe, and it does exactly what a downpipe should do.

RV6 uses smooth, full-radius bends so exhaust gases don’t crash into tight turns, and the turbo outlet transitions into the pipe using a cast stainless piece instead of a sharp welded step.

You want to free up the exhaust but you can't just bolt on a header like everyone else. The factory setup's got multiple cats integrated so you're choking on restriction no matter what. RV6 made this downpipe specifically for that problem. It bolts on where the factory manifold ends and gives you one clean piece instead of all that factory garbage. 300 cell high temperature cat. 2.5 inch outlet. 304 stainless throughout. Smooth cast transition. TIG welded and argon back gassed so the welds don't fail. You're getting better exhaust flow. You're getting lower backpressure.

You can't unbolt it. You can't swap headers because the cats are part of the manifold. That factory setup is restrictive. The tubing's small. The cats are low flow. Exhaust is fighting backpressure trying to get out of that thing. Your engine's not breathing right. You're losing horsepower that could be going to the wheels. We've seen people try to modify the factory manifold thinking they can make it work. You can't. It's a dead end.

No more multi-core cat mess. One high temperature cat. One smooth path. The cast stainless transition is engineered to flow clean. The 2.5 inch outlet bolts to your existing front pipe with no hassles. You're not fighting weird fitment issues or needing custom fabrication. Bolt it on and you're done. The manifold stays. The cat stays legal. But now the exhaust flows like it should.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt Right - Not Some Cheap Knockoff\u003c\/h4\u003e\n\n\u003cp\u003eThis is 304 stainless steel. The tubing. The transition. The outlet. All stainless. Every weld is TIG welded with argon back gas to eliminate impurities and make sure the welds last. The cast transition was designed in 3D and verified to fit right. You're not getting loose bolts or gaps that trash the flow. We've seen people buy cheap downpipes and they warp after a year of hard driving. The welds crack. The thing becomes a problem. Don't do that. The RV6 downpipe is built solid.\u003c\/p\u003e\n\n\u003ch4\u003eReal Power Gains - Not Just Dyno Numbers\u003c\/h4\u003e\n\n\u003cp\u003eYou're getting a noticeable bump in horsepower and torque with this downpipe.

You're still gaining real power but the number depends on what you've already done. Either way you're getting sharper throttle response. The exhaust flows cleaner. The engine pulls harder.

We run these parts too, because broken exhaust parts and boost creep excuses are not a vibe at the track Civic Type R exhaust level.\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat you get and why it matters\u003c\/h4\u003e\n\u003cp\u003eSkunk2 Racing builds this as a 304 stainless Civic Type R exhaust piece with mandrel bent tubing and TIG welded Civic Type R exhaust joints, then backs it up with thick flanges and an integrated stainless flex section.

If you want the most aggressive high flow Civic Type R downpipe option and you do not care about emissions equipment, this is the one. Style Catted, SKU SK2-412-05-6066, uses a Max Flow 100 cell platinum palladium honeycomb catalyst, so you keep most of the flow while cutting the raw fuel smell and taking the edge off for some motorsports rulesets. Neither option magically makes your car quiet, this is still a racing Civic Type R exhaust focused part.\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003eKey Features:\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTrue 3 inch 76mm Civic Type R downpipe diameter, helps the turbo breathe up top.\u003c\/li\u003e\n  \u003cli\u003e304 stainless tubing, handles heat cycles and corrosion better than cheap mild steel.\u003c\/li\u003e\n  \u003cli\u003eTIG welded joints, built for durability when you run repeated hot laps.\u003c\/li\u003e\n  \u003cli\u003eStainless flex section, lets the drivetrain move without beating up the piping.\u003c\/li\u003e\n  \u003cli\u003eUniversal 3 inch outlet flange, plays nice with the factory exhaust or most aftermarket 3 inch systems.\u003c\/li\u003e\n  \u003cli\u003eO2 sensor bungs in factory locations, you keep OEM sensor placement and the install stays straightforward.\u003c\/li\u003e\n  \u003cli\u003eOEM fit Civic Type R downpipe layout, bolts on like it should.\u003c\/li\u003e\n  \u003cli\u003eIncludes hardware, so you are not stuck reusing crusty fasteners.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Compatibility:\u003c\/h4\u003e\n\u003cp\u003e✔ 2017 to 2021 Honda Civic Type R (FK8) with the 2.0L turbo K20C1\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch5\u003eRace Use Only Disclaimer:\u003c\/h5\u003e\n\u003cp\u003eWARNING: This product is intended for race use only and may not be street legal in some emission controlled areas.
