After comparing this to the stock Y-Pipe you can tell the GrimmSpeed one will flow way better. Super easy to install. I installed this on my stock STI intercooler. I know GrimmSpeed sells the Y-Pipe and BOV gaskets separate but I wish they included them in the kit.

Fits good. But the supplied 90 degree hose will require trimming. 2 years ago
5out of 5stars

Overall, this is a very good product with its affordable price and quality casting. I bought this to replace my OEM 2011 WRX STI Y-pipe due to busted WMI bung. As stated on the manual, the supplied Grimmspeed 90 degree silicone hose will require trimming (to match the STI OEM 90 Degree hose) when paired with OEM turbo. What I did was re-use the OEM 90 degree hose because it is still in good shape, but I did have to eye ball how deep should the 90 degree hose be inserted into the Y pipe. It ended up to be a very snug fit, which is great. If I may provide a suggestion, it will be great if Grimmspeed supplied a measurement of how much to trim because I can imagine the difficulties of trimming the 90 degree hose if I do not have the OEM 90 degree hose as template.

As much of a PITA as you'd expect, but it wasn't that hard. Patience and time goes a long way. Installation took about 2 hours. I had to trim the silicone that connects to the turbo outlet.
