4 inch downpipe?

[boosted17]

Guys I want toget a four inch downpipe for my tuck just want some opinions on who sales the best an where to get it just shoot your ideas through

Too much work required to fit a 4" unless you do a body lift. And nobody makes a 4" for an OBS that I'm aware of so you'll have to buy an SD 4" down pipe and modify it to work.

Most of us use a 3" dp in an obs truck

Ok I kinda figured it would be custom but I'll take your word on the pain in the *** part haha I'll just keep my 3 inch it sounds dope just looking for a possible way to make more air flow thanks guys

3in is all you will need for these trucks. I thought I saw a 3.5" DP for sale somewhere. Either way you got plenty for what you are running.

Way to much modification needed for a 4"
