I also bought H Pipes off Walker in my day for an A12, Speedy Muffler bent every thing else up off their cards. I think I used the Hemi Mufflers and bought them off the dealership. There are left and right pipes that are not H pipes but never used them before. I also have a Stainless Steel Hemi Cuda H Pipe and if you want things to last a long time spend some extra money, maybe not the stainless steel way but good think wall pipes. Check around maybe there is old stock at Walker or CT or Midas in BC or Alberta.
