Features & Product Details

RallySport Direct is your number one source for quality upgrades and enhancements brought to you by COBB Tuning. 

 

The COBB Tuning Catted Bellmouth Downpipe has one purpose and that is to add more horsepower and torque.  It is a direct replacement of the highly restrictive factory downpipe, and it is the result of COBB's countless hours of engineering and testing to deliver the consumer a product that is satisfying in power and performance. This downpipe combines smooth mandrel bends with increased piping diameter that will reduce exhaust turbulence under boost which will increase both the horsepower and the torque.

    Another great Cobb product 8 months ago
    5out of 5stars

    I highly recommend this if you are looking for a high quality piece that is an easy HP increase over stock. If you pair this well constructed part of your exhaust with a tune, you won’t be disappointed!

    Very easy to install, just do it... 2 years ago
    5out of 5stars

    I wanted to retain my factory cat back on my 2006 STi so I went with this piece. The old exhaust piece came off with no drama and the new piece went in just as easy. Installed this and got a protune, very happy with the outcome. The only thing I will say is that I wish it came with a new turbo to down pipe gasket, I guess for some reason I thought that it would so when it arrived I had to run to the dealer fast to get one.

    04 FXT 5MT 5 years ago
    4out of 5stars

    I installed this on my FXT a week ago. Put about 1k miles on the pipe so far. Everything went smooth on the install. Only complaint is the welded on bracket. The bracket sits so close to the trans mount that it was rattling like hell upon acceleration and making a horrific sound. I ended up pushing the pipe as far away from the mount as possible (which is only a few millimeters away) then tightening the bolt to keep it away. Also cut a piece of fuel line and put it on the trans mount to dampen the noise. This is most likely caused by a few things like my old ass 04 trans mount with old rubber and other related bushings that have 200k miles on them. Other than that, it is an amazing DP and install went smooth with fresh gaskets and spring bolts.

    QUESTIONS & ANSWERS

    • Q: Does it fit an after market cat back exhaust?  ProjectWRX 7 months ago

      Does it fit an Invidia racing series fatback exhaust for an 07?
      • 0 of 0 people found the following answer helpful

        A:  This was built to fit with the factory exhaust, so if your Invidia exhaust works with your stock downpipe, it will work with this downpipe.

    • Q: downpipe  marcoave10 months ago

      I currently have catless downpipe and i was wkndering will this DP make the car more quiet? And also i had my car protuned to my catless DP would i need to get my car retuned for this?
      • 0 of 0 people found the following answer helpful

        A:  It will quiet the car down a bit, but it won't make a massive difference, but you will hear it. And technically you could run this without re-tuning the car, but we would always recommend a tune for sure. Thanks.

    • Q: Installation Hardwre  av3fire12 months ago

      I have a catted Cobb downpipe for 2002 WRX The features says no installation hardware included is there an installation hardware kit available? with gaskets and nuts/bolts
      • 0 of 0 people found the following answer helpful

        A:  Cobb expects you to re-use your factory hardware if you're hooking it up to the stock catback, but if your hooking it up to an aftermarket catback you will use the hardware that comes with the catback. I would however recommend getting a new turbo to downpipe gasket. thanks

    • Q: Fitment  ooosorio1 year ago

      I have a 2013 wrx hatch. Will this link up with my tomei CBE?
      • 0 of 0 people found the following answer helpful

        A:  This will not fit your 13 WRX. You'll want part number COB524203, and you will also need GRM077046 to bolt it to your Tomei catback.

    • Q: About cat.conv. in downpipe  UAAC1 year ago

      Why did Cobb switch 400 cpsi cat. in this downpipe instead of 200 cpsi one in old version (part number: 512202)?
      • 0 of 0 people found the following answer helpful

        A:  Unfortunately, we cannot speak on behalf of the manufacturer.. I would recommend contacting Cobb directly to see if they can answer your question.
