Don't get me wrong it does help free up exhaust flow. But it not fitting and leaking at band clamp is.a big deal to me. I put this on customers car had 5 hours trying to get it to fit bought a different band clamp and put dents in it so would clear.frame. it still leaks. Cut ac box heat shield. And brain tells me my whole body is not on frame correct. Have no problem paying big money for parts but they should fit. I have engine out now and recutting pipe and tig welding pipe together so no more leaks. Yes I will have to pull engine to remove pipe but better than leaking. And yes I have h-r parts and stuff engine mounts.this is pic of test pipe he sent me. It was chrome mild steel with nasty booger weld it was to be stainless steel with nice tig weld. It took month and a half for him to send me flange and pipe and I cut it to length and welded it myself. He has done good things for turbo buick community but fabricator he is not.
