[QUOTE=u155282;464256]Couldn't you just put them further down, past the collectors, or anywhere else where they would still do their job but not interfere with other functional elements? Maybe I don't know enough about it...
No because the distance from where the LTH meet 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.
