Ok, So I get a used Roktec muffler in great shape go to the muffler shop actually 2, they say it won't fit. The guy I bought it from had it installed with a Cat still on. I have looked under the truck and it looks like the cat outlet bends down and the original muffler is an offset offset? I thought about pulling the cat and saving it and connecting a 4" straight pipe to the Roktec then use the original outlet pipe. I know people use 51" donaldsons and they work should this Roktec work on my truck. --Thanks
