R1-Spec Dual w/o Resonator Catback Exhaust - Subaru WRX/STI VA [2015-21]
Installation Guide
One of our most aggressive looking systems for the 2015-2021 WRX/STi. Features dual R1-Spec muffler canisters with 4 inch slant cut tips. Designed and manufactured for the performance minded enthusiasts. The R1-Spec features 3 inch mandrel bent piping and high flow straight through muffler design.
This system is offered without a resonator located on the midpipe. The two 150mm O.D. canister mufflers effectively control the exhaust note. We feel the style matches the sound. Looks aggressive and sounds aggressive.
There is a noticeable difference between non-resonated and resonated, but it is not a huge difference. We recommend the resonated version if you prefer a quieter exhaust note, and/ or plan to add other exhaust or turbo related components.
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.
