i have a M6 dumdumdumdumdum with a bunch of boltons, currently the car has LT's to a ORY into a Flowmaster. I want to put true duals on it that will dump at the rear axle. The car will ocasionally see nitrous later on in the season, but will mainly be my DD. I will use two bullet mufflers: should I run 3 inch duals, or should I go down to 2.5?

Thanks for your help

can someone chime in?

it depends on how much HP your pushing. I think that 2.5 inch duals are good for 500 HP, 700 for 3 inch duals.

you should be fine with the 2.5 inch, and have more clearance to.

If the car is going have more mods in the future,ie.h/c/i,n20,etc., then yes, I would opt. for the 3" piping.
