Features & Product Details

Add more power and performance to your vehicle with the COBB Tuning Stainless Steel Turbo Back Exhaust System. 

This exhaust system begins with the COBB Tuning's 3" Catted Downpipe. The main purpose of this downpipe is to lift the restrictions of the factory downpipe with a design that features smooth mandrel bends and increased piping diameter. Additionally, this downpipe has a high-spun catalytic converter that makes it environmentally friendly without affecting the performance. 

When combined with the COBB Tuning Stainless Steel Exhaust System you are substantially lifting the restrictions from the factory exhaust system. Now you have a downpipe and a cat back exhaust system designed with smooth mandrel bends that limit turbulence under acceleration which increases horsepower, torque, and you get improvements in throttle response, fuel economy, and reduced turbo lag. 

Both the downpipe and the cat-back exhaust system will come with hardware and gaskets to make it ready for installation. The cat-back exhaust system has been built with exhaust hangers on the OEM locations so that you don't have to perform any further modifications to the body or chassis.

COBB Tuning Stainless Steel Turboback Exhaust ( Part Number: 515331)
Cobb Turboback Exhaust  2 years ago
_STI
I am so happy I got this. I paired these with the Tomei EL headers and it sounds awesome. When looking for a turboback for my car I was looking for an exhaust that wasn't too loud but better than my stock ones and Cobb did it. These make almost no sound at cruising speeds but when pushed hard you can hear the engine open. I also like the pop-ups it makes when downshifting, I smile every time lol. Installation was bad at all even though the Cobb hangers were challenging to installed but as far as exhaust everything went well. One thing to keep in mind is to re-use the exhaust donut in the midpipe or you will have leaks. Overall Im am very satisfied.

QUESTIONS & ANSWERS

  • Q: 2015 WRX STI  MIke WRX STI 153 years ago

    Currently im at stage 1 with SF air intake if i install this is there a map that allows both sf intake and this turbo back i only see maps with stock airbox and turbo back
    • 0 of 0 people found the following answer helpful

      A:  When using a downpipe with an intake the stock injectors on the 2015 models are unable to keep up. The downpipe will bump the vehicle into Stage 3. COBB has a Stage 3 map available on their site but injectors and fuel pump are required. We recommend checking COBB's map notes on their website for more details.

  • Q: Tuning  oppey420943483 years ago

    Does it come with a tune you can upload with a accessport?
    • 0 of 0 people found the following answer helpful

      A:  This turboback kit itself does not come with a tune, but if you have the COBB AccessPort you can apply the Stage 2 tune for these items.
