NA... im pretty sure it's an axle back and its proper piping "loud" meaning
deeper tone then stock, odviously seemings how the car still has 2 cats and one resonator to begin with, with a muffler the size of a kitchen sink...

 

sorry guys for the sloppy sentence... but i just used a apexi N1 muffler that came off my old 98 GSX and cut the piping, then cut it again to make the bends, weld the seams and flange and dont forget the hanger and she bolted right up no prob and the car loves it, i can tell because she purrs better... lolol jp but when i can finally download the new pics u will see that i didnt mount at an angle, i put two 90 degree bends into her so she lined up with the bumper cut out and shot her straight so it looks clean...
