I can see why feel you had less performance
I may only have a 3rd grade education, but that sure reads like you're calling bs to my experience
For the last several years I've had a 91 with the stock 22re except for a k&n stock replacement filter, and I'll find out soon enough whether or not I'll lose power or mileage when I install my 2.5" system on it. My prognosis is no, but that's only from having the same system on another nearly identical truck
Again, none of this is beneficial to the original poster. I strongly suggest snowtoy starts his own exhaust tubing size thread and see if any facts can find their way into it, or if it'll just be more theory.
