exhaust pipeing

[Red_Diesel]

where can i get 5in or 6in exhaust system? i want a 5in or 6in straight pipe.

check with farmboysdiesel. hes a vendor. He can hook you up...Prolly wouldnt go no higher that a 5" on a stock truck. I believe you start to actually lose some power when you get that big with a stock motor. I think. Im not sure

With a stock truck, I would go with a 4" system.....A 5" kit is really not much different, as it the Down pipe is still 4"....The 5" is slightly throatier......My friend actually has a 5" turbo back exhaust that dumps into a 6" pipe with a turndown tip on it, it sounds sick.

As mentioned before check with Gus at FBD...You can also piece together your own kit....Buy a 4" downpipe, and than go from there..... Do you want a rear exit exhaust? A dual exhaust? Or a turn down under the truck?

[Red_Diesel]

i want a rear exhaust i think, maybe duals

[blizzardwarrior7]

If your going to go with duals, go with a 4" system.....MBRP and Magnaflow both make good kits...MBRPs tend to be louder and more aggressive sounding, and Magnaflows tend to be a little bit mellower, and smoother sounding.

Just an FYI but a dual exhaust on a diesel is for looks only really. The extra section of pipe doesnt help cool EGT's any further

[blizzardwarrior7]

Um....Actually they sound pretty different as well.....And I would think that it actually does lower your EGTs slightly but maybe not measurably, as longer piping=lower egts...

Yeah, I would go with a 4", espeacially if you want to dual it out. I've got a 4" turbo back straight and really like the way it sounds from Farmboys

Yes they do sound a little different thats obvious because the sound is routed in two different directions. But as i stated there is no " measurable" difference in the cooling affect a single exhaust has vs a dual.
