you know...i saw on the news that the new thing in cally is exhausts that whistle, try those

 

Bub Rub and Lil Sis.... Wooo Woooooo!

 

(two DNX mufflers + custom axle-back dual exhaust) - DNX silencers = Loud, deep and throaty exhaust tone.

Personally, I keep the silencers in, since under about 3k rpm, it's just as quiet as stock, but a lot more aggressive, but I've had the silencers out before... it's nice and loud.

Actually, if you want a really pronounced car? Get an intake and a header, as well as exhaust.

Oh, and be careful... DNX mufflers aren't street-legal...

 

Holley Thundermuff is about the loudest exhaust out there....except for one of the buddyclub mufflerless exhausts.
