so im just starting to mod my dads yukon denali to make it a little better for towing our trailer. it has already had a maggy on it for a while now but now im getting headers and a LS6 cam for it. and now im wondering if i should run a 3 or 3.5 inch exhaust for it...

thanks for any input!

 

I think 3" will be fine.. Superchargers don't pick up as much from larger exhaust as do turbos from what I've seen.. Just do 3" with a good straight through muffler

 

thats kinda what im thinking, but it just doesnt make sense that a supercharged 6.0 should have the same exhaust as most people run with a N/A 4.8... ya?

 

anyone?
any dyno data?
