4 inch Magnaflow Turbo Back

I have MBRP turbo back... Fit perfect and looks killer... all exhausts will do the same... but some just fit better and quality may be better

I have straight pipe dumped before rear tire, No muffler. There is NOTHING like the turbo whistle of an 04 6.0L.



Besides an 03 6.0L

But if a full system is a must MBRP 5in, Can't beat it for the money.

any of the ones mentioned above are good, I am using silverLine and I have no complaints
Farmboy's has an aluminum kit that they sell really cheap, but since you live in NY and have bad winters with lots of salt on the roads, it would be worth paying a bit more for stainless steel

Not to be hated, but I don't think I would expect a real large increase in fuel economy with a lot of these mods. Don't get me wrong I would not change anything I've done, but it was not what I expected as far as fuel economy is concerned.
I definitely suggest the exhaust, just don't be disappointed.

I have a 4" Magnaflow on my daily driver and a 5" MBRP on my race truck and both were a perfect fit and sound great but the 5" MBRP sounds WAAAAAYYY better.

I do agree here, I would only expect lower EGT's with the exhaust, And the ability to safely MOD for econo mods, IE SCT or other.

+1...between exhaust intake and tuning im seeing maybe 2 mpg. the best benefit from the exhaust is lowering EGTs. brought mine down on averge 100-150* (Silverline Duals, 4" turbo back w/ muffler)
