running truck w/o muffler?
Hey guys i just received my new Roush off road cat-back today and was going to install it in the morning. I wanted to take audio of the stock exhaust, no muffler then the new Roush. The question is can i run the truck with no muffler for a lil bit with out it throwing codes or messing something up?

theres no specific way to break in a muffler, just drive it like you want to. it'll get louder as you put miles on it.

you'll most likely lose some bottom end torque.
