Description

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 research 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. This will also result with improved throttle response and reduced turbo lag. 

This downpipe has been fabricated from 304 Stainless Steel, and the piping diameter is 3", however it does taper down to the 2.5" stock flange for those of you who are going to retain the stock cat-back exhaust system.

There will be two O2 provisions for those who need to install their O2 sensor or an optional wideband gauge. 

Because this product replaces/removes an OEM emissions control device we must state that this product is for offroad use only.

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.

Impressive Bang for the Buck
James Livingston 2 years ago
I bought this for installation by a very good shop on my 2007 WRX, at their recommendation. Since they did the installation I can't comment directly on the fit of the part, and the box was too big to invite opening when it was delivered. Getting the car back from the shop was a real treat; its responsiveness was quite noticeably improved, coupled with the up-pipe and the ECU remapping done with the Access Port. All in all, just what I had hoped for.

  • Q: tomei expreme ti mating up?  RELprojects 4 months ago

    Answer

    I recently bought the tomei ti extreme catback exhaust, wondering if this cobb will match up because on the picture shows the flange isn't flat and has that donut gasket pipe at the very end. As for the tomei flange is flat. would it match up or will that cobb pipe flange get in the way?


    • A: For the best fit between a 3 inch flat flange like the Tomei and a donut flange like the Cobb an adapter is recommended. An adapted rlike the Grimmspeed GRM 077046 works well for this connection.

    Answer

    Do l have to reflash my ecu after installing the downpipe? Is it safe to run the car without it till l get the cobb accessport?


    • A: Tuning will be required when changing out the downpipe. We would recommend installing the Accessport at the same time as the downpipe.

    Answer

    I was looking into this downpipe and wanted to know will this bolt up to the ETS cat back exhaust?


    • A: The ETS catback might have a 3" connection and would require an adapter since the Cobb downpipe has a 2.5" catback connection.

    Answer

    Hi, I'm looking to replace my stock Cats with this downpipe and mate it with the stock exhaust system. Everything on my 07 STi is stock. I do have a couple of concerns: 1) Do I need a different turbo to DP gasket other than a stock one? 2) Will This throw a CEL even though it is Catted? 3) Will this come with the gasket needed to mate with the rest of my stock exhaust piping? If not, will the factory ones work fine? Thanks!


    • A: You will need a new turbo to down pipe gasket. A Cobb Accessport is strongly recommended, as you will need an OTS map from Cobb. And this down pipe has a 2.5 inch flange and will mate correctly to the OEM exhaust. It is recommended to replace the OEM donut gasket as well.
