Not Ranked
Hi Rare Iron:
I replaced my original CCX mufflers with the 20" baffled Classic Chambered mufflers in the largest ID (for a street 428 FE) plus new turnouts. I grafted these on to the original collectors as it's explained on the Classic Chambered website. There was a noticable improvement in power with much better flow with no appreciable difference in A/F ratio. There was also a significant increase in noise levels over the originals, earplugs are required now. Overall, I'd not hesitate to do over, although I might look at a longer CC muffler (they advertise different lengths) to reduce the decibels.
BTW, Classic Chambered customer service was first rate.
Thanks,
Kirk
