In stock, no waiting! The Invidia R400 Gemini Single Layer Quad SS Tip Cat Back Exhaust for your Subaru WRX / STI 2015-2018 is among one of the most popular cat-back exhaust systems available as they make for an excellent upgrade over the OEM exhaust system to improve the performance and the sound. The combination of increased piping diameter along with smooth bends relieves the exhaust with restriction and turbulence under acceleration which will increase the horsepower, the torque, all while improving the throttle response and reducing the turbo lag.
Here are the key features:
- Stainless steel quad exhaust tips
- 4" Tip sizing
- 304 stainless steel materials
- 3" piping diameter
- Exhaust hangers welded on to the OEM locations to allow for a direct fitment
- New gaskets and hardware included making this exhaust system ready for the installation
Note: Are you using a stock j pipe or downpipe? If yes, the GrimmSpeed Subaru Stock DP to Aftermarket 3 in. Catback Adapter p/n 077046, is required.
The exhaust arrived the day after it shipped, which was absolutely unexpected. UPS damaged the box and one of the flanges during shipment, at no fault of IIR or Invidia. I cleaned up the flange and made it usable again. The welds are great, and the quality of the exhaust is exactly what you would expect from Invidia. Highly recommended!
This exhaust sounds amazing, shipping was extremely fast and great pricing I couldn’t be happier with my experience at Import Image Racing definitely recommend getting parts though IIR
Sounds amazing, easy install, quick shipping. You won’t regret putting this on your car!
