I probably should have posted here first, but have already ordered the following. It will replace the existing 4" X 2.5" spintech oval pipes with track mufflers already on the car. Its a 800 hp pump gas, 540 hemi motor with 2 1/4" headers.
5" X 2.5" oval stainless pipes and Spintech stainless mufflers (sportsman). Thinking about oval electric cutouts as well, but I'm not sure I need them.
I plan to tig weld everything up over this next month.
Any suggestions on the cutouts? Will the flow of the new (bigger) pipes and sportsman mufflers be ok?
