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.

awesome product
Lawrence72 4 months ago
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!

Great Prodcut

Excellent build quality, great fitment for my 09 XT. Definately faster spool and HP & TQ gains with a tune.

Fit like a charm

I installed this onto a 2010 STI hatchback. There was no fitment issues whatsoever. The quality of the material was impressive with a nice finish. I wish I had looked more into how many bungs I needed before ording; I had to add another bung for the AFR gauge and it was troublesome getting this done. Overall very impressed with the product and would order invidia products again.


  • AnswerQ: BOOST CREEP!  jrodz_198971448 30 days ago

    Is EWG w/catless or catted downpipe the only way to "PERMANENTLY" remove creeps? If yes, any recommendation either catted or catless what are the pros n cons?

    • A: Boost creep is standard when running a catless downpipe, but running a catted downpipe should not give you any boost creep with a proper tune. The only true fix for running a catless downpipe would be to either port the internal wastegate or switch to an external wastegate. A catted downpipe is cleaner for the environment but will make a bit less power, a catless will be a full straight-through pipe and be much louder, but usually make roughly 5whp more.

    I have 2011 sti with Cobb v3 access port, Cobb sf intake, and invidia n1 exhausted would this dp be ok to run or do I need a custom tune ?

    • A: The Cobb off the shelf maps are calibrated for their catted downpipe. You can run this downpipe on the accessport maps at your own discretion .

  • AnswerQ: BOOST CREEP  jrodz_198971448 1 month ago

    Is this the best catless downpipe to pair with EWG setup (Tail 38mm + grimspeed up-pipe + dump tube) does the divorced westgate matter? or go with catted? Inputs would be helpful, thanks!

    • A: There isnt necessarily a best downpipe to pair with an EWG setup. The divorced wastegate design essentially becomes useless if you go with an external wastegate setup as the internal wastegate does not open. A bellmouth downpipe would be more beneficial. If you do not want to go with an EWG, then a catted downpipe would be a better option.
