Invidia N1 Cat-Back Exhaust for 02-05 Honda Civic Si

Invidia N1 Cat-Back Exhaust for 02-05 Honda Civic Si

If you're looking for a sporty sounding exhaust upgrade for the 02-05 Civic Si,  the Invidia N1 Cat-Back is a solid pick. This Invidia exhaust uses SUS304 stainless steel with a polished finish, so it holds up to real weather and still looks good under the car. You also get CNC machined flanges and mandrel-bent exhaust piping, which means the tubing keeps its shape through the bends instead of necking down and choking flow. Less restriction usually shows up as better mid to top end pull, especially once you add common bolt-ons and a tune.

Variants:
