Wich one O/R X-pipe will fit with MAC long tubes and Flowmaster cat-cack

DR GAS all the way and it will sound FINE with the flow masters, but i do agree you should ditch those mufflers for something that flows... like a MAC flowpath orspintech prostreet... they sound insane with an x pipe
 
Yup fit was great on the VRS..and i was worried about the sound of a X and flows..but mine sounds fine

I run MAC 1 3/4 LT's and the x-pipe fit no probs
