I purchased some band style clamps in 2.25" to start some testing and modding to my exhaust. 2.25" will not clamp down. I don't believe, contrary to popular belief that we have a 2.25" system on our cars. Unless Gm uses thinner walled pipe than normal. It was close but would not tighten up. I have now purchased 2" one and I will get a actual inside measurement when I cut it. Unless someone can enlighten me.
