You want loud? Get rid of the cat and throw a 14" 4x9 Magnaflow on there. Fully straight through and small enough to not silence your exhaust that much.

Or just skip the muffler and have headers straight back.

Oh... and make sure to throw some really big and long chrome tips on there... I had dual 3.5" tips with 2" exhaust and no muffler, just cat and my cousin heard me coming from 2 miles away. It echoed acrossed a lake.

had strait pipe on my v6 4 a day once lol they start soundin very simillar to a v8 around 3000 - 3500 rpm but other than that sounds like crap lol! a good high flo cat some big pipe and a performance muffler will give u a nice loud exhaust note and if done properly will sound o so good!!
