Glasspacks?

You probally want to keep in mind that to legally pass the decible test your going to have to put 30+ inche glasspacks on the car, they are the best bet if your going for the most power because its the closest you can get to a straight pipe, but anyway if you want a loud impressive sound on a daily driver you could consider putting cut outs on the car and run some kind of remote on it, iv heard of people using R/C Car Servos for doing this, but anyway i agree with 6T9PONY go with full exhaust with packs. my .02
