I recently bought an F7 exhaust for the blaster that I'm rebuilding. I measured the exhaust with my caliper and it measured at 1.13 inches on the outer diameter and 1 inch inside diameter. Should I order a 1 inch coupler, or a 1.25 inch coupler from siliconeintakes.com? I know that obviously the 1.25 will work but I'll have to clamp it down a little tighter, just asking for some advice here!!
