goin with o/r i think
 

i have a catted prochamber with my mac a/bs i think im goin to make it o/r what you guys think and then down the line when i get headers ill put high flow cats in

I just bought the MAC L/T's and the O/R prochamber. Ill post a before and after as soon as they get here

Well you will be replacing the entire midpipe if you get LTs down the road. So if you are "buying" a new o/r pipe you might as well wait so you are not spending money ont the same parts again

im goin with shorties down the line so i will be ok with that
