Features & Product Details

One of the most common performance modifications you can perform on your vehicle is the addition of a Cat-back Exhaust system. But note that not just any exhaust system, but the COBB Tuning Stainless Steel Cat-Back Exhaust System. This is the result of countless hours of design, research, and testing to develop an exhaust system aimed to deliver performance and sound. This is achieved through smooth mandrel bends that limit exhaust turbulence under acceleration which is combined with increased piping diameter. Not only do you get improvements in power, but you get improvements in throttle response as well as reduced turbo lag. 

Because this exhaust system has been fabricated from 304 stainless steel, you are getting an exhaust system that can last the life of your vehicle while saving weight and adding value. And don't forget about the benefits of a more aggressive exhaust tone under throttle.

Included with this exhaust will be gaskets as well as hardware to make this COBB cat-back ready for installation.

It’s absolutely gorgeous! 7 months ago
5out of 5stars

Cobb always seems to make a super high quality product, when I opened the box, I thought mine was damaged in shipping! Take a close look at the stock photo assembled. The “dent” in the Midpipe is intentional. Probably for clearance, but scary when you open up an exhaust you’ve wanted since 2009! I’ll post a bottom picture of the muffler on my bed. It’s absolutely incredible in person. (Even made my wife sleep on the couch!) 10/10 would buy again. I’m installing mine on a 1995 Subaru Impreza LX. (Requires Grimmspeed adapter and a little exhaust fab on the Cat pipe) Wanted a turbo exhaust so when I buy my turbo swap, everything will just bolt right up! Super excited!

Just what I was looking for. 8 months ago
5out of 5stars

I was on the hunt for a Cat Back Exhaust that would give me the WRX sound but piss of my neighbors. This is it. I love the clean sound it produces and the quality of the product is outstanding. I highly recommend this product if you are looking for an upgrade from stock.

Matted to a Tomei 3" downpipe. The sound is very satisfying. Gas mileage got slightly better. Overall quality product and I would buy again!

Fit perfect with my aftermarket down pipe, sounds great and so much better then stock, but not overly loud so i don't piss the neighbors off.

QUESTIONS & ANSWERS

  • Q: Tune?  KW2 years ago

    Will this require a tune after installation? Everything ls on the car is stock. Thanks.
  • Q: hp limitation  vegnpwr3 years ago

    When matted with a 3 inch dowpipe, what is the max recommended horsepower given the 2.5 inch bottleneck? I have a 2004 sti with 475-500hp at the crank.
    • 0 of 0 people found the following answer helpful

      A:  Through extensive testing Cobb has found that is not a significant restriction until well over 500 Hp. While it can impede air flow slightly, it wouldn't be a difference until numerous other restrictions were resolved on the car.

  • Q: Additional Parts for installing COBB CBE to 2005 Subaru WRX STI  JoshSti3 years ago

    What other parts do I need to install the COBB CBE to my 2005 STI if I have OEM Down pipe? I'm still deciding which CBE to get, COBB or Q300.
  • Q: 2002 Subaru WRX w/ Grimm Speed Downpipe  Padillar4 years ago

    How does the Cobb exhaust stainless steel mate w/ a Grimm Speed Downpipe?
    • 0 of 0 people found the following answer helpful

      A:  This will have a 2.5" flange at the down pipe connection and if your Grimmspeed down pipe has a 3" flange, you will need an adapter.

  • Q: Hardware  StarryBoar5 years ago

    Do you guys have to know bolt sizes? DP to mid and mid to back?
    • 0 of 0 people found the following answer helpful

      A:  Catback hardware is going to be M10, we recommend bringing your hardware into a hardware store and sourcing replacements.
