One reason people like myself have sooooo much money in our cars is we don't think far enough into the future or we are not planning on making alot of power. Well power is easy to get used to and we end up replacing things twice because what we bought first wasn't sufficient for later down the road. If you plan on keeping your car go ahead and get the massives with the piping. If you sell, keep them and get a chunk back. Just try to do as much at one time and do it right. Don't have the money save till you do.
