If I swap to the Manifolds.
1) Should I still use a X-Pipe? Head pipes then X-Pipe that is.
The one I have Can not be used as it was made as,a,3 inch to come off the Headers and go to 2.5 inch.
So would need 2.5 head pipes and 2.5 X 2.5 X-Pipe.
2) Since I have 2.5 cutouts should I use them with manifolds?
As in Head Pipes, X-Pipe, Cutouts. Muffs,and Tail Pipes all 2.5 inch.as,far as,sound wise that is. Not sure how and X-Pipe would sound without Large Tube Header
Or how Cutouts for that matter with Manifolds. With or without the X? Would an H be better?
Asking since I am sure some here have run manifolds and X or H.
And may be silly enough to use Cutouts with out Headers.
