I know this has been covered a few times but i cant seem to find the info that I researched a while back. Im thinking of running rams horn manifolds fed into a 2 1/4 or 2 1/2" y-pipe system then having it go into 3" single all the way back.

Is it better to go 2 1/4" or 2 1/2 " till it comes together basically i need to know what size reducers/collectors to buy.

I have the exact same exaust and I run 2-1/2
Get a Flowmaster Y 2 1/2" inlet to 3" outlet. Then run 3" all the way back.
cool thanks guys i guess ill go with the 2 1/2 to 3 then
:cool: you wont regret it, my 6000lbs+ blazer moves along just fine with a single 3" coming from center dumps, anything lighter kick ass!
