Exhaust Gasket: OEM or Aftermarket? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Wilcats · 05-21-2015, 03:15 AM

Hi guys. I'm replacing my headers/pipes with after market ones (2.5"). Just wanna ask if the OEM gaskets are okay or will the aftermarket ones like Grimmspeed are better replacement? Its double the price than the OEM.

Thank you!

I used OEM for the header gaskets, they were a bit more forgiving and helped fix the leak at the flange. The GS ones leaked, not because they are poor quality but because the flanges were not 100% flat

I'm using all Grimmspeed gaskets, header, and OP/FP. Nice part is they can be re-used because I ended up changing catbacks at least 4 times and my front pipe once.

I think my exhaust addiction is over though, but the gaskets work great for the price you pay.

Thank you for the feedback sir. I guess I'd just stick with the OEM ones.

Cheaper too! (in our country
