Kill that exhaust leak for GOOD!
Exhaust leaks seem to be an all-too-common issue with most modded Subarus. 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. Compare our adapter to the competition and you will immediatly see why we offer the best solution to finally end that pesky leak.
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 we flared out one end to just shy of 3" so that unlike the competitors, our adapter will not block flow!
A Final solution to pesky problems, it's what you can expect from GrimmSpeed™
NOTE: GrimmSpeed 3in. Gasket and OEM Subaru Donut Gasket SOLD SEPARATELY
Fitment Note: Adapter is only inteded to be used for connecting aftermarket 3in Downpipe to OEM style catback. It can not be done in reverse.

"The part itself is good. Be wary the bolts that come with it are too short for many DPs out there, in my case with a Perrin pipe I could not get it threaded on with a washer, I had to go without for now.
Shame on you Grimmspeed, when the product is a universal part, you should make sure the bolts are plenty long, not like there is a clearance issue at the DP flange.
Review marked down because it is really annoying to have to complete a product when the included hardware is inadequate."

This adapter made my Invidia DP install MUCH easier, and, most importantly, with the doughnut gasket, sealed well! As with all GS products, this piece is very "over engineered", with a nice beefy flange and a nice smooth transition between the DP and the factory cat-back. Anyone who is thinking of installing a DP to a 2.5" CB should consider this a necessity! Great product that no one (except GS) seemed to think of before...genius.

Just received mine today. As usual the quality is top notch! The flanges are thick & the welds are perfect! I had recently purchased one from another vendor and the Grimmpseed adapter FAR exceeds the quality of my other adapter.
