RV6 3 Inch Front Pipe for 22+ Civic Type R/Integra Type S

RV6 Performance 3" Front Pipe - FL5 Civic Type R & DE5 Integra Type S

The factory front pipe on your FL5 Type R or Integra Type S is a choke point. Honda used a 2.37" outer diameter mid pipe on the latest Type R and Type S, which is far too restrictive for a turbocharged K-series making 315+ horsepower. This RV6 front pipe fixes that: a full 3" OD 304 stainless pipe that replaces the factory unit and bolts directly to your factory exhaust or any aftermarket cat-back. Your turbo can finally breathe the way it should.

Full 3" Construction

The entire pipe is built from 3" OD 304 stainless steel tubing. Everything from the turbo flange to the exhaust connection is stainless, including the double-lined interlock flex pipe and all the flanges.

RV6's master welders TIG weld the entire assembly in the USA and back purge every weld with argon, so the inside looks as clean as the outside. Back purging matters on an exhaust component, an un-purged weld oxidizes on the inside and becomes a corrosion point you can't see until it fails. This isn't a cheap slip-fit pipe with spot welds; it's hand welded end to end.

Where It Sits, And Why It's Worth More Than A Cat-Back

Worth understanding, because it explains where the gains come from.

The exhaust flows turbo, emissions section, front pipe, then cat-back. The front pipe is closer to the turbo than the cat-back, which is why opening it up matters more, you're reducing backpressure where exhaust gas is hottest and moving fastest, right behind the turbo.

Going from the factory 2.37" to a full 3" here frees up the biggest single restriction in the FL5's exhaust path. Run it with a 3" cat-back and you've got a consistent 3" system from the turbo back, which is the combination worth building toward.

How It Compares To The PRL Front Pipe

Since these are the two front pipes most FL5 owners cross-shop, here's the honest comparison.

Both the RV6 and the PRL front pipe are 3" 304 stainless, both back-purged, both direct bolt-on, and both do fundamentally the same job of replacing the restrictive factory 2.37" pipe. They're closely matched on the fundamentals.

The RV6 uses a double-lined interlock flex section and is offered in three finishes (raw, silver, or bronze coating). Choose based on finish preference, price, and whether you're matching other components on your car to one brand. Either is a genuine upgrade, so it comes down to the details rather than one being clearly better.

Direct Bolt-On, No Tune Required For The Pipe

The routing and hanger locations match the factory setup, so this bolts directly to your OEM exhaust or any aftermarket cat-back. You're not cutting, welding, or fabricating anything, just unbolt the factory front pipe and bolt this in.

The front pipe itself doesn't require a tune to install and run. If you're building toward more power and adding other bolt-ons, tuning gets you the most from the fuller setup, but the pipe alone is a straightforward bolt-on.

Three Finish Options

Available in raw stainless, silver coating, or bronze coating.

Raw stainless will patina and discolor from heat over time, which is normal for bare stainless and bothers some owners and not others. Silver and bronze coatings help the pipe hold a cleaner appearance longer by resisting that heat discoloration. Pick based on whether the pipe is visible on your car and how much you care about it staying pristine.
