The Invidia Catless Downpipe features a Divorced Wastegate, this will separate the exhaust gas exiting the downpipe, creating a smoother exhaust flow, thus resulting in more HP and Torque.
Invidia's all new downpipe is a great way to start adding Horse Power and Torque gains. The Invidia downpipe is constructed of 304 stainless steel tubing to ensure longevity while enhancing power by freeing exhaust flow. 3" mandrel bent piping will bolt up to any stock replacement catback or stock unit.

Your car must be tuned to run this downpipe

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

Great downpipe.
Hizzle 27 days ago
2013 Subaru WRX limited.. Went on pretty good except the heat shield. I cut it up a few times and looked hideous. Wouldn't go on so I left it off. Maybe that's the next purchase. I matched it up with the invidia race exhaust. Sounds great!! I have a Cobb access tuner and had the engine code show up 1 time with a flashing cruise light and the TCS light stayed on. I cleared it and ran the car with the TCS off and haven't had the codes come back after I cleared them. Getting a pro tune next week.

Perfect fitment & loud!

looks and fit great on my 2010 wrx. I painted the pipe red with high temp exhaust paint and wrapped it with thermal wrap. It didn't noticeably change the tone of the exhaust but definitely made it louder. bolted up to the stock mid pipe fine. Great bang for your buck

she sounds beautiful

install wasn't difficult; just a bit time consuming. But everything fit, although I needed an adapter to mate it to my magnaflow exhaust system. No fits great (read that as no leaks) and helps the exhaust flow better, if not a bit louder. My guess is that if I had to do it again, I would get one with cats (the smaller cats, not the same as on the OEM), as the cats would help reduce the fumes coming out of the exhaust. Reminds me of the 60's, both in exhaust smell and the drug induced coma you will get if sitting in traffic for too long with a tailwind blowing. No matter; I enjoy it and can feel the extra oomph due to this pipe.

Great product. Extremely well made. Super easy to install once you get the stock garage out of the way. Would recommend buying the GrimmSpeed gaskets as the stock ones either brittle or its torn. Definitely opened up the car and complements my Invidia N1 perfectly!


  • AnswerQ: Fitment  csyto 2 days ago

    I have a stock 2014 wrx with nameless axlebacks will I need to purchase any adapters fir this?

    • A: The axleback will not have an effect with the downpipe, but if you are still using the stock midpipe you would want the Grimmspeed 3" downpipe to stock catback adapter as well as a donut gasket. Beyond that all that is needed to install would be a pro-tune.

  • AnswerQ: Downpipe  ronemanuel1049364 15 days ago

    I have a magna flow cat back exhaust, what adapters do I need to run this downpipe?

    • A: Make sure your verify your catback has a 2.5 inch flange, if it does you will need the part listed below. If your catback has a 3inch flange you will not need an adapter, and a 3inch 2 bolt gasket will work perfect.

  • AnswerQ: additional hardware  justice 1 month ago

    i have a stock 2011 wrx exhaust. will this fit without any special adapters or is there anything else i need to buy

    • A: You will need a 3" downpipe to stock catback adapter similar to the unit Grimmspeed manufacturers and that we carry. An OEM donut gasket and turbo to downpipe gasket is also recommended. Beyond that, a pro-tune will also be needed.
