    Duals

    Since LS1tech isn't giving me any luck I'll ask here. Heres the set up I want to go with: Pacesetter LT, CATs, TSP Rumbler Duals. Here are my questions tho. Which muffler out of the 3 they offer will be the loudest without sounding like a tractor trailer or being too raspy? Can I run the factory cats off of the Pacesetters or do I need to get high flows?

    I've had a few people tell me to go with the Sweet Thunders because of the bark and choppiness of the idle with a stock cam.

    I agree and would go with the sweet thundes myself. You have to realize you're dumping before the rear axle so you're just gonna have to deal with a little rasp and drone. Comes with the territory.

    A little isn't that big of a deal to me. I like dumps alot better simply because it reminds me of alot of the old school muscle cars I see at car shows.
