    tsp stops before the axle. made to fit a few headers. check local laws about where the exhaust can dump at.

    bassani runs duals into one muffler that is a dual in/out design. exits out stock location. made for 00-02 stock manifolds and cats. minor work to fit to headers. you can see on my webpages. no need for aftermarket suspension parts. i have it on both cars. minimal interior noise, versus other exhaust systems. made 15 rwhp more over the borla 3" adjustable catback that was on the wife's car.

    I personally went with the TSP TD's due to the fact I was ordering Pacesetter Long tubes at the same time. They hooked right up to the Pacesetters. I enjoy the sound but my wife hates how loud it can be at times inside the cab. So depending on how much you can tolerate you may want to go with the Bassani. I am sure my wife would appreciate it if I did but she doesnt ride in the Trans am much any way so I dont plan on changing anytime soon.

    Love my Bassani , best investment I've made so far in my WS6... Here's a sound clip with stock manifolds and cats: I added Pacesetters and high flow cats since the clip, but haven't made another clip since. It's a little louder now, but still manageable. I'll post one when I get it...

    I run headers, 3" duals, and Flowmaster 2 chambers on my SS Monte Carlo. I only drive it on occaision. It sounds like open headers. I like that sound, but not on my TA. The drone gives me a headache after a while, and my wife hates riding in the SS because of it. That's why I chose Bassani for the TA.
