I have a full SLP including longtubes and the x-pipe w/powerflow cats. Instead of the lm2s i have the powerflo catback and it sounds mean. It gets very aggressive as the rpms climb and it doesn't break up either. Fitting this exhaust together is cake once the headers are on. Not allot of people would go for this set-up unless you could get a deal on it because slp is still expensive. If i were to do this for my sisters auto i'd buy a set of shorty headers, and an offroad x or h-pipe. They would sound mean and the shortys would look nice with the hood popped instead of those rusty manifolds.
