so i know that on my LX i wont be picking up much power with a cat back exhaust so why spend the extra money?

so i was hoping that i could find a WS2 muffler and maybe have a shop weld it on for me. i like the sound of the ws2 on the other cars that i've heard, but is it possible to do that?

or should i just go ahead and get the whole cat back system.

also if its possible to just get the muffler could you show me some good dealers? thanks guys
