GR Performance exhaust
 

My 24 gr86 came with the GR performance cat back. It wasn't much louder then stock. I just installed my SME header and overpipe, and a Berk front pipe with hfc. It sounds pretty good now, and no droan.

Nice - :thumbsup:

Heard it in person, sounds great!

tbh, I can't tell the difference between the GR Performance exhaust and the stock exhaust from outside when the revs are above 4k.

Here's a video I made back in the day:

(same observation with my own ears)

The GRPE sounds louder than stock at idle.

Sounds like stock header correct?

What's up with the tack welds on flanges?

Fully welded on the inside. Tacked on the jig to ensure perfect placement.

Correct, stock header.

I thought this was a thread specifically about GR Performance exhaust and didn't realize you had other components changed as well :)
