I'm looking at getting the Gibson split rear (cat-back) or the Borla T-304 split rear (axle back or cat-back).

I'm wondering if anyone's used these, and how the performance is with them?

Also wondering (with the Borla) how much of a difference the cat-back makes over (or under) the axle-back?

As always, any/all help is appreciated!

 

i have the borla axle back sounds perfect not to loud not to quiet. i love it. really easy to install too.

 

How is the power? I've heard there can be some loss with duals?

 

yea i heard the same thing i just put in the single. besides i was not a big fan of the duel. they hung a little to low of the read bumper for my liking. i have so much other stuff done the power was hard to tell but it made a difference. nothing crazy sounds great though would recommend to anyone
