Getting my 2003 Grand Prix GT worked on next week(long shifts causing it to eventually slam gears and also stuttering acceleration especially from stops or up slight hills. Think it may be something electrical and clutch packs but feel free to give your opinion in your post) then after that is out of the way I plan on getting a new exhaust. I currently have a Wizaired CAI(Which I LOVE) and a stock exhaust other than two Flowmaster Super 40s. I love the sound of the 40s but it is just a little to loud for me, especially coming home from work at 1am at the top of a big hill because it's awkwardly loud at specific low RPMs going uphill. I'm thinking of getting a 2.5" zzp catted downpipe with a magnaflow resonator and a pair of mufflers. I would really appreciate any input for a good sounding, somewhat quiet, preferably deep and non-raspy exhaust. I'm thinking magnaflow or borla but will take all suggestions.

If this is the wrong section I will be more than happy to move it somewhere else. Thank you.
