I personally recommend the stealth setup. Its plenty loud. I cant even imagine how loud the race is. But I also have race headers with a high flow cat, so I'm not positive what leaving the stock exhaust manifold on (with both cats) and adding the exhaust setup will do for your sound levels (decibels).
I had both for a bit , with the fswerks "street" setup . It sounds great but knocking out the 2nd cat brought the db,s up a lil , well at least my mind says it did , lol
