I just bought a Borla cat back for my Z. I know they're really expensive but i know a guy so i got a sweet deal, still spent a lot though. My question is, is borla really worth the money or should i have spent less on a cheaper brand? Also how much horsepower on average does a cat back give to an LS1? The website says as much as 10% but that would be 30 horsepower and that seems a little much for a cat back.

 

Face it. In this life, You get what You pay for. Borla is about performance AND quality.

so my borla just came in a few days ago...i backed the car up on some ramps to take a look underneath and it looks like i might have to start doing some cutting before the muffler....will everything come off and bolt up alright? im only on ramps not a lift

 

you can't take the stock stuff off without cutting it, unless you drop one side of the read end and bring it over, i cut mine up with a recip.
