Cat backs will not make much HP over stock. You need long tube headers to increase HP much.
Thats going to be ridiculous loud
Is this worth it

How much more power can be had by converting the Catback and just the CATBACK to look like this:

Practically NONE
Modifying, replacing, by-passing etc. to the cat-back of our exhause will yeild very little extra horsepower if any. It will increase the db of your exhaust note though, which is why most people replace their cat-back. I personally did the by-pass mod due to the cost effectiveness of the operation and am very please with the results

That car at an idle is one of the few corvettes I have heard that truly sound like a muscle car. Like everything else, you get what you want and can afford. That system sounds awesome, but with a "normal" bolt on engine, it can't be much if at all more beneficial than a good set of LT's with X-pipe and "normal" cat back. I love the sound though,,, on someone else's car.
