    It’s absolutely gorgeous! 1 year ago

    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!

    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.

    • Q: Flange size/ bolt pattern  @7700XT11 months ago

      Is the flange/ bolt pattern the same as the stock exhaust at the beginning of the axle back pipe?
    • Q: Tune?  KW3 years ago

      Will this require a tune after installation? Everything ls on the car is stock. Thanks.
    • Q: hp limitation  vegnpwr4 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  JoshSti4 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.
