Any power loss?Originally Posted by KWright
Ran these on my 565's. Good alternative to the gils with no tailpipe modifications. I was very pleased with the quality.

over gils I highly doubt there would be. From a long tube sweeper style yes. It’s pure runner length. Originally Posted by bigboat28

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. Originally Posted by green lightning

if you already have gils these seem like the best bet. You don’t need new risers/tails.

nice. So you’ve had them a while and they’ve held up. That’s good to hear. Originally Posted by green lightning
