Never ran them In comparison with the gils. They were an upgrade when I built my 565's. I knew i wasn't keeping my 35, so I didn't want to spend a ton on complete new exhaust. We made good power with them over 750. I would use them again if I didn't want to do completely new.

how long have you had them? I’m really thinking this is the route I will go. Don’t wanna drop a fortune on all new stuff. My tails are already fairly new.
