COMBO: R1-Spec Catback Exhaust PLUS Front Over Pipe - Honda Civic Si FE1 [2022+]

Our R1-Spec full exhaust plus 3" front over pipe making this a true cat-back system. Larger diameter piping, straight through muffler design for improved exhaust flow and reduced back pressure. Unlock more performance from your 1.5L Turbo engine. 

We offer the exhaust and front over pipe separately but this combo is offered at a special price when purchasing directly from our site. We also include the OEM plastic garnish to fill the driver's side tip cutout which we feel completes the single exit look.

The front pipe uses 3" mandrel bent piping and includes a reinforced flex for longevity. R1-Spec utilizes 2.5" mandrel piping and high flow muffler canister. Includes a straight through resonator located on the midpipe to help reduce drone. Single exit 4" tip provides a performance aesthetic. 

A common question is why not make the exhaust 3." During development we tested a full 3" version but there was an excessive amount of drone at commonly used RPM range. Increasing the size of the resonator or muffler canister did not solve the issue. Potential performance gains between 3" and 2.5" are insignificant at stock or near stock power levels.
