I have a fairly stock 91 Prelude. The only mod I know of is lowering springs supposedly. It is an auto. I would think exhaust would make it nice because of the sound. I hate the sound of it right now. It sounds like a clunker. I would imagine a CAI would be cool, again for the sound. My brakes suck, but I dont think there are any real decent brake kits out there. I might have to get them checked out by my mecahnic. Any ideas on what would make this car the most fun to drive keeping in mind bang/buck ratio..
