RES Valvetronic Catback Exhaust Demo - Subaru WRX STI | 4enthusiasts

Sound demo of the RES valvetronic catback exhaust on my WRX STI. Note that the STI doesn’t have good sound deadening from the factory so interior sound is already loud. I do have engine/transmission mounts which create alot of NVH so a WRX/STI with stock mounts can be much quieter

Specs:
- 304 Stainless Steel
- 3" piping
- 4" exhaust tips
- Non-Resonated
- Stock downpipe
