Have a race car and looking for a way to make instant horsepower? Invidia’s downpipe is always a good start. This particular downpipe was tested and documented in the late but legenday Turbo magazine. They concluded that when combined with the cat-back section, the HP gains were seen up to an astonishing 60+ at the wheels with engine management.

This downpipe is made out of 304 stainless steel with a larger bell mouth. The piping ID is 3”, and should bolt up to most catback or stock units.

Please note that because this product replaces/removes an OEM emissions control device, we must state that this catless downpipe is for off-road use only.

The end of the downpipe didn't match up with my cobb catback .. 1/16-1/8 inch gap after installing the gasket, going to have to go to a shop and have them figure out the best way to fix it... overall can't complain, its a fairly cheap pipe, sounds great with my tomei el headers/up pipe and cobb catback

Car came with an unknown brand 3 cat-back with a 4.5 tip. I was afraid without the cat it would be too loud, but it is purrrrfect! Running stage 2 with Cobb EBCS. Perfect fit, great sound, no boost creep that I've noticed, and the added power is absolutely wonderful. I don't see anything wrong going with the cheapest option for your DP.

Couldn't be more happier. Looks good, light weight. Easy to install, expect the part of taking off the stock DP. Love it.

Great product overall

I love this DP with the Invidia N1 race exhaust , it sounds so aggressive , but my only problem is the DP and the cat back are having a hard time aligning , so unfortunately i have a exhaust leak , so it doesn't sound that nice , if you want to go stage 2 and go cheap with out compromising quality this is the way to go.

Great price, great upgrade.

Had a vendor order this for my 2002 WRX through RSD. Makes your exhaust tone meaner and the stage 2 map is a huge upgrade. Be prepared to snap some bolts on your old downpipe when you install this.


  • AnswerQ: Stage 2  eric.cornellier28448 2 months ago

    I have the AP and N1 catback, im on stage one, would the stage 2 tune work with this? considering its catless or would i have to get another map for catless specificly?

    • A: The Cobb Access Port is designed to tune Catted downpipes. A catless will usually require a protune. for more tuning information visit.

  • AnswerQ: Differences?  Colbyschaeffer2124485 3 months ago

    I am comparing this to the Invidia divorced catted dp. I love the price of this but which of the two is louder? And I'm getting my car tuned in a week or so, will I have to retune it after I put either of these on it?

    • A: A catless downpipe will be louder than a catted pipe and both would require a tune to run safely. If you are getting tuned in a week with a stock downpipe, You will want to retune after you install an aftermarket downpipe.
