An 8" tip is a little "tool like" for my likings but if that's what you like go for it. I think you'd be better off with a 4" straight pipe
The engine is bone stock right now but I will be installing the H&S tuner. So if I go 5" straight pipe over the 4" then I'll lose power?
Ya I think so but talk to a local diesel shop see what they say also make sure its straight piped when you get it done SENT FROM MY EVO IN MY F350
A 4" turboback will be plenty big enough. My buddy had 450hp with a 4" straight pipe and wasn't looking at changing anything. Here's a dudge with a 5" pipe and 6" tip.
Haha and are u sure that's a 6" tip? I had 6" tips on my last F250 and they didn't look that big. That looks like 8" doesn't it?
I have a 4" turbo back with a 6" tip and its getting off soon I'm not a fan SENT FROM MY EVO IN MY F350
