catted y vs. bullet in I pipe
so far i switched from a magnaflow catback to a hooker but im still not 100% happy with the sound. So my question is which would be a better option to go with to get rid of rasp without losing to much performance? My options are pacesetter LT's with a tsp catted Y and slp DD or going with the pacesetter LT's with a tsp ory and slp DD with a borla xr1 bullet in the I pipe. Which option will flow the best and stop the rasp?
