Hello all:
I currently have the set up listed in the signature. I find it hard to satisfy the need for more power for my daily drive to and from work.

Slowly creeping up.
1. I know there is a difference in performance, but should I expect a significant difference in
feel between high flo cats alone vs LT w/hi flo cats with the MACH XL cat back?
2. Should I expect a significant difference in sound (volume) between high flo cats alone vs LT w/hi flo cats with the MACH XL cat back?
Any experiences with this combo (any LT headers) + Solo MACH XL cat back?
Any video/sound clips would be helpful too. Cannot find much via the search.
Thanks!
