Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno)

No because the distance from where the LTH meets the block to where they meet the exhaust is a certain distance. That distance is the same as stock headers + cats/HFC combo. Most if not all of the exhausts are made to fit up to the stock mounting point. If you add onto the LTH by adding HFC then you would need a custom exhaust with adjusted measurements to mate up to it.

Not sure if I explained that well enough but I gave it a shot.
