New Exhaust Help
Folks,
I plan to upgrade my stock exhuast but I am not sure what size my stock system is. I have a long bed 2001, extenda cab - everything is stock. I am planning to install a high flow cat and a flowmaster big block 50. I need help identifying the size of my pipes; in and out. Many thanks.

I'd go with 3" all the way out! I just have the stock with a y-pipe and 1 40 series single in, dual out with 3' turndowns..sounds pretty good, wish I could afford true duals though
