Exhaust question?
IDK if I'm in those links above, but I used the Jegs kit with my Hooker Comps and the 2-1/2 exhaust pipes fit preety darn good while being quite enuff at cruise to drive for hours without issue. Loud, but not over bearing when you hit the gas. IMO, it was very well worth the price. Easy to instal with only a small trim at the tailpipes for evening out the tail pipe ends.
Get it new from Jegs.
