I am looking into gettig a Diamond Eye downpipe for my truck. I want to make sure it can take 8 to 10 hrs pulling a fifth wheel. Has anybody out there pull with this type of pipe?

Well I guess that that mfg is not any good. Why is stainless steel better?

 

Replace the whole exhaust system

just go full exhaust it is cheaper in the end. i would say 5'' your factory is 4''

 

It's no use replacing just your down pipe and keeping the rest stock you best bet is buying a complete system
