@Orr89rocz

should beable to get this thing on the JSdyno easier… lol

Do the 3", its worth it. Plenty of room to run it, atleast on my car. Looks like room under the 4th gens to do the same.

If you do single, i’d do 4 into dual 3 if you want dual outlets. 2.5 will choke it too much

well i have the Centermount exhaust and tips are 2.5" inlet. dual 2.5 is still more diameter then single 4". i plan to run a cutout for track
