Bought the 3" Summit exhaust system
Nice. I was going to comment on the 2-1/2 system I got from Jegs, in which I wouldn't doubt it is from the same place that summit gets there stuff from. The fit was good and the tail pipe needed minor trimming, but I skipped it in favor of tips from headman. (Turn downs.)
I just simple assembled it all up but didn't tighten a thing until a general clearnace was reached everywhere on it. Then as I tightened it up, I did it slowly from front to back going over it a few times. Like torqueing down a cylinder head. Doing the pattern 3 times kind of thing.
It took a little tweak here and there, nothing serious. Though 3 inch is a bit bigger than 2-1/2.
