Description

Exhaust leaks seem to be an all-too-common issue with most modded Subaru’s. They tend to spring up out of nowhere and cause hours of troubleshooting headaches. The most guaranteed leak you will get though is if you run an aftermarket 3" downpipe to an OEM or OEM like 2.5" Exhaust.

Cut from steel and hand welded these pieces were born tough. With the ability to work with both flat style gaskets AND donut gaskets they cannot be matched. If that wasn't enough they flared out one end to just shy of 3" so that unlike other adapters, this one will not block flow!

I wanted my Forester XT to have more get up and go, but not at the price of letting people know from a mile away that I am arriving. So, no melon-shooter for me - I get to keep my incognito exhaust, and keep the volume of my gigantic GrimmSpeed downpipe at a minimum with this puppy. It bolted up perfectly, no leaks. Thanks for keeping me on the DL, GrimmSpeed! Note - you will still need the downpipe gasket, as well as the stock donut gasket for this to work correctly, and make sure you can scrape the crap out of what is left of the stock donut gasket if you want it to get a good seal. So long as you do, this should work out great for you.

Fitment issues

I installed it on a 04 wrx wagon with a no name downpipe. The quality of the part is fantastic, hardware is great quality. Yet for my instance I have yet to find a way for it to not leak at the 2.5 end. I have the correct gaskets, just can't get it to stop leaking :/

  • Q: Spring bolts  Fxtrunner 2 months ago

    Answer

    Should you use the stock spring bolts if using the doughnut gasket? If not should a flex pipe then be welded into the cat back section?


    • A: You would use the bolts supplied in the kit, you could always weldit on if you want to go that extra step as well.

    Answer

    I bought a catted invidia downpipe and was wondering if this will fit to the dp and factory exhaust system


    • A: Yes, this paired with an OEM style donut gasket will be the correct adapter for a 3 inch downpipe to a stock catback.

  • Q: Gaskets  EJNick 11 months ago

  • Q: 3inch midpipe to stock cbe?   Jacksont345 1 year ago

    Answer

    Will this adapter connect a 3 inch invidia mid pipe to the OEM 2.5 catback? Or will it only work with the stock mid pipe directly to the Invidia 3 inch Down pipe?


    • A: This is designed to fit a 3 inch down pipe and mate up to a OEM catback. We are not able to confirm fitment anywhere else in the exhaust system.
