[QUOTE="biminiLX, post: 15726828, member: 7795"] Considering I made 965rwhp thru factory mufflers, I doubt it's a big loss. As I said above, do it for sound not power. Maybe 10rwhp? Eventually I'll do dumps and will check both ways. I also laid out the entire stock exhaust system in my driveway and there are a few restrictions in the pipes but at 2.75" it's flowing well. -J [/QUOTE]
