Thanks for the quick replies guys. Regarding the tubing size, most of the generic research I've done suggests what you recommend -- 2 1/4" max for this application.


On Jolly's site however, he seems to suggest a much larger size in his performance upgrades section (hopefully no issues in copying this here).

"Better Exaust System
Dual 2-1/2 to 3 inch exhaust pipes is a nice improvement, and the 50 series Flowmasters Mufflers sound great on these engines. "
