they hook the emissions up to the obd. in mass as long as the tailpipe exits 20" past the passenger compartment it is 100% legal. ive passed emissions 2 yrs running with the bullet dumped b4 the axle

mine is nowhere near 20in past the pass compartment unless you are only counting the front half. it may be 10in past the rear doors.

ya i have no idea how or where they measure from mine seems to be in about the area of 10 -20 lol. either way no probs as of yet and like jess said it seems to be sounding better and better as the weeks months go on
