Invidia's V2 downpipe is a great way to start adding Horse Power and Torque. This system was tested in Turbo Magazine, they found that when combined with the cat-back section, HP gains were seen up to 60+ at the wheels with engine management.

The downpipe is constructed of 304 stainless steel with a large bell mouth will ensure longevity while enhancing power by freeing exhaust flow. 3" mandrel bent and bolts up to any stock replacement catback or stock unit. This downpipe also has an extra oxygen sensor bung welded in so you can install a wideband oxygen sensor and keep the stock one in tact. It comes with a plug installed so you don't have to worry about not having one.

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

So I bought this to match up with my n1 street!!!! Great product but it didn't match up too well, it short about 2 inches but luckily I have the 3" flange from grimspeed when I have 2.5" stock dp to my 3" catback. So I used that , it work out fine. Nice sound, deeper rumble and performance is alittle more quicker

I bought this downpipe after reading many reviews and talking to people who have this product. Frankly I was a little disappointed in the quality. The bellmouth and the downpipe to catback flange are made of a cast alloy that appears rather cheap and doesn't seem like it would hold up structurally for years to come. Sound wise its a bit tingy at idle. Other than that it works as designed and fit to my perrin cbe very well. Overall I'm content with it on my car for the time being but I will be changing it out when I change turbos.

Excellent product, excellent quality as expected by Invidia. I opted for the 2-bung DP so i could run a AEM UEGO (havent done so yet). Fitment was perfect, and it really opens up the exhaust. Turbo spool is loud (I had a Blitz NUR-R catback, now custom straightpipe) and I love it. Bolts right up to any stock catback, or aftermarket catback designed to work with factory DP.


  • AnswerQ: Unknown catback   Fernando C. 2 months ago

    So the guy I bought my 2006 WRX from had a unknown brand of catback, but it bolts right up to the stock DP. So should this easily bolt up too?

    • A: This is a stock length OE Replacement downpipe so as long as your catback fits with the stock downpipe this should match up.

    Will the first bung that is closest to the turbo act for the turbo gauge?

    • A: The Bung by the turbo will be for a wideband air fuel ratio gauge. A boost gauge will tap into your vacuum lines under your hood.
