I love the sound of headers going to stock cat back, so I just added some DMH low pro e-cutouts. Sounds AWESOME.

Go to Maryland speed & get a Bassani. Then have the center muffler replaced with a X-Pipe. You will love it.

I vote Spintech as well. Car just sounds mean when you romp on it.

It always cracks me up when people try to claim the Magnaflow is as quiet as the stock exhaust. No way.

magnaflows are just quiet at idle. If you have the straight through design, they're going to be loud at WOT

It's quiet at idle like mentioned.

Also, with headers and cam of course you're going to make a magnaflow loud...hell your stock exhaust will be loud also with those.

If you just replace the catback with a magnaflow one, it's gonna idle and cruise quieter but will scream at WOT mainly due to the no resonator.

Off topic a bit but, how restrictive are the stock mufflers? I know the piping after the mufflers have all sorts of kinks.

Your question is 100% subjective, but
