my muffler on my Monte Carlo 3.1 is rusted right through the middle. it actually sounds pretty good and is decently loud but i want to get something else. i was thinking something like a flow master 40? what other options are there that would sound and perform good. i dont want it to be overly loud but i want it to be noticable. also will it have to be welded on or can you use something like a clamp

 

Get a Flowmaster 40 series delta flow and have it welded on at an exhaust shop. The tip changes sound drastically too, just so you know.
