GrimmSpeed V2 Bypass Valve Subaru WRX 2015-2021 / Forester XT 2014-2018 - Black | 126033BLK

Good so far

Got the bypass valve and turbo inlet installed easily. Worked great with the grimmspeed ebcs and charge pipe and intake. No tune required. Stalled three times in the first 30 miles but seems ok now. I’ve got about 70 miles on the setup. Intake noises sound a little crisper if that makes sense. Still haven’t pushed it that much but expect it to be more reliable than the old setup that cracked.

Amazing sound and quality

Fits like a glove and sounds so good. It’s the closest sound you can get to the classic turbo flutter from the other brands bpvs. Way better than stock build and sound wise

Quick and easy

Website is super easy to use and received the parts I ordered very quickly. Will be ordering from them again very soon.
