Description

The COBB 3" Stainless Steel Cat-Back Exhaust System has been designed to improve the performance, the looks, and the sound in your vehicle. This exhaust system has been designed with minimal bends that reduce turbulence under pressure which relieves back pressure for increased horsepower, increased torque, and improvements in throttle response and reduced turbo lag. 

This exhaust system has been fabricated from quality 304 stainless steel materials which should last the life of your vehicle and endure the elements. The piping has been TIG welded and exhaust gasses go through a combination of 3" and 2.5" piping before exiting quad 3.5" polished tips. Exhaust hangers are welded onto the stock OEM locations so no further modifications are required on the chassis or body for fitment. 

Hardware, as well as a gasket, are included to make this exhaust ready for installation. It is also compatible with the stock, or COBB Tuning downpipe.

Review from a 46 year old . . . 2016 WRX
Weldon 2 years ago
I searched hi/lo - scoured the forums - watched numerous youtube vids . . . With so many options and opinions it was hard to narrow it down. I was looking for a natural/normal increase in the volume and quality of the exhaust note - not a muffler delete "hey look at me - i'm on my way to Riceville!". Have to say this is the best sounding aftermarket exhaust I've ever installed - just the right tone and volume - louder than stock, but not too much. Also, this is the first CBE that I didn't have to use a torch and crowbar to get everything to line up right - the fit was perfect and centered before I even tightened up the flanges. Also, when I had the stock tune I noticed a difference in performance - the torque dip at 4k-ish was less noticeable and seemed to pull smoother to redline. That was a bonus I was not expecting . . . Doing business with Rallysport has been a breeze - never used them until this purchase - I look for price, quality and service - they nailed it. Good job, guys.

  • Q: Full 3"?  BettyWhiteS207 2 years ago

    Answer

    I am reading something that states 2.5 to 3 inches... I just want to confirm that the catback portion of this part is 3 inch piping as I know the cob catted downpipe tapers to 2 1/2".


    • A: The flange that connects to the downpipe is tapered to 2.5 inches and then it will open up to 3 inch exhaust from there. The 2.5 inch downpipe flange allows better fitment for OEM downpipes.

  • Q: mid-pipe diameter  lilkasino 3 years ago

    Answer

    What is the size of the mid-pipe, where it connects to the downpipe?


    • A: The flange at the downpipe tapers to a 2.5 to allow better fit with the OEM donut gasket and OEM downpipe flange.

  • Q: Grimmspeed downpipe   lilkasino 3 years ago

    Answer

    What adapters, if any are needed to mate this to a grimmspeed limited downpipe?


    • A: You will want the GRM 077044 adapter from Grimmspeed. Use this adapter in conjunction with an OEM Donut Gasket.
