Thread: Idea's on how to make my car sound better for cheap?

Hmm ok maybe I'll just leave it stock. One more question, I'm reading the how to safely mod your 3800 thread right now. But my car has 161k on it, 150k when I bought it. Is that to much to start modding, and adding HP? The guy I got it from was some old guy who took care of the car he had it all written down. It is on its 3rd tranny though, all replaced by him, which is weird to me. Also is a 3.4 pulley setup even a noticeable gain in power? Because I don't plan on going any lower.
