I would like to upgrade to a performance exhast but I do not want something that is loud. I like the current sound of the stock exhast but I want the something that will give me the best of both worlds. Quiet but with performance. What'* good? And what about the cat back does it also increase the noise?

Headers and hi-flo cat with a stock exhaust sound really good on my car. Not to loud as to wake the neighboors but definately enough to perk up somebody'* interests. They will allow you to moderately mod your car as well as give you approx 20hp or so by themselves.

I added headers this winter and kept the original cat back exhaust. It is a bit louder but more a growl than a bark sound. I plan on taking out the cat and res later this spring and maybe replacing the mufflers?
Flowmasters have a nice throaty groan, dynomax are a bit more aggressive and raspy?

Thinking I'm going Corsa mufflers and tips! Along with some TOG'*

I have pretty much the same exhaust set up as you fellers, and my Magnaflows sound great...

However the V8 rumble is a bit different.

I pimp Magnaflow
