If your looking for horsepower/ 1/4 times go a twin 2.5
or twin 3in if your gonna upgrade to a cam later on

If your looking for a loud/lumpy sound a Single 3.5 is your exhaust

I can do a twin 2 1/2" cat back with front mufflers and tail pipes for $690 shipped. Sounds good, lumpy on idle and great note under acceleration.
