I'm gonna put an X pipe in my 3" exhaust system that includes full length Schoenfelds, Dynomax Ulra Flo muffs.......I Know the original X pipes that look like two pipes cut and rewelded add a lot to the system...I have used them....but does anybody know anything about these stamped steel units that are all over the place now?? In theory they should work the same...
