2 1/8" TTI Headers

What kind of modifications did you have to do to run the Mazzolini 2 1/8" headers besides the obvious inner fender holes? Is it because you're running the raised port heads? I would also like to see some more pics of your Mazzolini headers if possible. I just ordered mine today.

watching this closely! do u guys really think an x pipe will be beneficial on a motor that big? will it even be worth it`s own weight? got the parts for a 3.5 system for my barracuda, but am having trouble with all the weight it will have.
comments? would sure like to see dyno tests of the x pipe together w/ ur header tests!----thanks, bob:coffee2:
