Has anybody noticed any low end change after installing cross over. I made my own 3 inch, but bought 3 inch ceramic. Seems less low end tourqe droped off a bit. Any comments appreciated.

The factory exhaust manifold isn't designed well for flow.
The additional volume of the crossoverpipe allows the combustion gass to expand and may dampen the lowend torque.
I know custom headers would change that.Edited by: quantum mechanic
