So the big question: Run 2.5" and ding (dent) as needed.
Or..........................Run 2.25 and no dings(remains to be seen)
Input welcome.
HP is not a big goal, but hey Hot Rodders gotta Hot Rod!  |
I have had quite a few Mark VII's, and the tailpipes neck down smaller than 1 3/4 in the tailpipes. If you can run the 2.25 and make it fit well, it shouldn't affect performance. On the VII, it is quite an accomplishment to fit 2.5 all the way out.
