Perfect Gasket
cade8537 1 year ago
Perfect for exhaust setups that dont come with gaskets or this works as a perfect replacement gasket for any 3inch exhaust.

Used with GS 3 DP to stock CBE adaptor (spt exhaust)

Sealed up perfectly! I out the DP to CBE gasket a little over a year was literally all rust and pieces fell out when I unbolted the DP. Put this in there with the GS 3 DP to stock (SPT) CBE adapter, sealed up perfectly! I don't expect any exhaust leaks ever again.

GREAT general purpose 3 inch gasket

I used this to mate up a shorty downpipe and midpipe. It is really thick and heavy, much more confidence-inspiring than the razor-thin sheet of metal I replaced it with. Gaskets are one thing you REALLY shouldn't save money on and this one is a perfect example. WORTH IT.

This fit my 3 pipe perfectly, the product looks to be very durable, buy this if you want to never have to replace your gaskets again.


  • AnswerQ: OEM to catback exhaust.  Panda 4 months ago

    So I goofed up and bought this instead of the GrimmSpeed OEM downpipe to catback (GRM 077046) gasket. My question is, can this still be used this for my OEM downpipe to Invidia N1 catback?

    • A: GRM 077046 is an adapter as well as the gasket while this is just the gasket. This gasket alone wont provided the same fit and seal as the flange adapter (GRM 077046). when using the OEM downpipe.

  • AnswerQ: gasket fitment  rudy 4 months ago

    Will this gasket also fit the muffler to the midpipe for a 2014 wrx hatch using an invidia q300 exhaust?

    • A: We recommend using this at the downpipe - midpipe portion due to how thick it is.

  • AnswerQ: 02 WRX  futbolrunner 7 months ago

    Will this work with my TurboXS 4 in downpipe to race pipe paired to a TurboXS catback?

    • A: We are not able to confirm fitment, as this is a universal product. This gasket will only work on 3" 2 bolt flanges, so I recommend measuring to verify the sizing on your application.

  • AnswerQ: Exhaust fitment   Isaiah 9 months ago

    I have a HKS carbon titanium exhaust on a 2002 wrx. The exhaust diameter is 75mm and the downpipe is 3in. Will this gasket work between the two? Also would this work from the midpipe to the muffler on the same 75mm exhaust?

    • A: This is meant to go between the downpipe and the catback portion, for exhaust with 3inch flanges. 75mm is about 2.9 inches so the fitment should be fine. This is not meant for the mid pipe connection.
