Hey everyone,I am soon to be forced induction via a magnacharger.I am currently running obx lts and ory.For exhaust i have a magnaflow exhaust with about 3 inches of 2.75" pipe from the collector into 3" muffler then 3" out to 2.75 to the back.I want to shorten to make a custom side exit.Will it hurt performance if i reuse some of the 2.75" stock exhaust for my outlet to the side or should i buy some 3" pipe for the outlet.I dont think the inlet will hurt much will it as i stated above.Let me know you think and i dont want to dump it so thats out,(personal reasons from fumes that happened to a friend of mine).Thank You ill be looking forward to your replies.

Edit:this for a 4.8l 2wd.

I would have to say that should be suffecient for airflow, but I am by no means a FI guru.
