    Perfect fitment from invidia catless 3 inch downpipe to factory exhaust ( legacy gt auto). No leaks used a donut gasket on factory side and flat gasket supplied with downpipe on downpipe side.

    Item does what it is meant to do. Easy install, just make sure you have a good gasket as well.

    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.

    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  Fxtrunner5 years ago

      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.

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