Im building a duel exaust for my 84 ta and had a question about witch type of crossover to use if any.I could easly build a H pipe or would i see anymore of a gain with an X. Any info would be helpful.

Thanks

 

Either will do about the same (for power) and both are benificial. Unless you're making a fine tuned race/drag car, pick a winner and stick it on.

 

How far back should i put the H or is that something else that realy dont matter?
