R1-Spec Dual w/ Resonator Catback Exhaust - Subaru WRX/STI VA [2015-21]

Check out one of our most aggressive looking systems for the 2015-2021 WRX/STi. It’s got dual R1-Spec muffler canisters with 4 inch slant cut tips. The straight-through resonated midpipe helps control sound and tone. The R1-Spec features 3 inch mandrel bent polished piping and a high flow straight through muffler design.

This system has a resonator on the midpipe that reduces exhaust volume and noise without much restriction. You’ll notice a difference, but it’s not a huge one.

If you want a quieter exhaust note, or if you plan to add other exhaust or turbo parts, we recommend the resonated version. Just keep in mind that adding other performance exhaust parts can make the exhaust louder and change its tone. Keep this in mind when selecting resonated or non-resonated version.

Offered with polished stainless steel tips, or burnt finish stainless steel tips. The burnt finish is achieved using a chemical process. This vibrant finish will fade over time depending on use, cleaning, and care.
