Exhaust size?

I'm getting ready to straight pipe the new truck. What size is the exhaust?

Ive heard 3.5 inches - 3.8 inches - 4 inches.

I wanna mke sure I put the exact same size pipe back in place of the existing muffler.

thnx

I thought I read that the 600's had the full 4", whereas mine had a 3.5" all the way back to the 4" flare just behind the muff.

It wouldn't hurt to crawl under there and measure "twice".

The 600 has a true 4 in exhaust all the way from the turbine outlet to the tailpipe.

An offset pipe will help too, the outlet on the muffler is not in line with the inlet. Geno's makes one, my local muffler shop was able to order me one, wound up being cheaper out the door than doing it from Geno's would have been even before shipping. Also, you're gonna need a chisel or gas wrench probably to get the stock muffler off of there.
