ok right now i have pacesetter LT's ORY to a borlamouth and i was wondering if i would get better power with the gmmg catback i also wanted to know which is louder thanks

 

Same power, different sound. Check out www.ls1sounds.com if you haven't done so already. Cheers.

 

No power to be gained.

 

I agree with the previous post's..no power gain just sound difference(quality) and I like how the Borla tips look...JMO.

 

the difference in power would not be a big differnce either way. i think the setup you have currently would be louder than if you switched to the gmmg.
though, if you have the money the gmmg would be a good call since it sounds so good!!
$700+ for just a catback is steep for a catback alone, i would rather have duals over the axle with some chambered mufflers.

 

i was reading on a few other threads people saying that a good TD custom setup would be a lot more expensive than the gmmg like it would cost around $1500
