7.3 straight exhaust
 

I need a cost effective way to get my truck louder. Any suggestions? And will it help gas mileage, even marginally? Thanks!:c:

Cut out the muffler and replace with a piece of pipe... that's about as cost effective as it gets... And no, you will not gain any MPG's by doing this...

Should I buy the mbrp piece or just any 4" exhaust tubing

Any pipe will work...

if you have stock exhaust you'll need 2- 3 1/2" to 4" reducers

ok thanks....can I just get the reducers at any exhaust shop?

Some exhaust shops have larger pipe but you can find a pretty reliable stock of 3"+ exhaust pipe pieces at any truck/industrial supply store.

I'd caution against a straight pipe on a Powerstroke....they sound a lot better with some sort of muffling device.

well that's just personal opinion. i have mine straight piped but i never had a muffler on it when i got the kit so i don't know.

By the time you get done monkeying around with exhaust, you would be $ ahead by purchasing a Summit Racing 5" system and running it w/out a muffler. It starts with a muffler delete, then you wonder what a bigger cat back will do, then you realize you don't live in a smog area and the POS dealership sold you a truck without a cat anyway, so you add a down pipe. With each bigger piece, the non existant mpg gain has taken a back seat to how cool your rig sounds and the extra power you have freed up! Aluminized is mandatory, stainless if you want it to out last your rig.

I spent more money "saving money" on my rig than if I would have dropped the cash the first time! :argh:

Never heard, or even thought I would have heard that one....

Just get a section of 3 1/2'' pipe to replace the muffler... Cheap and effective.

Like was said, just an opinion...I never did like the sound with a straight pipe and went back to a Magnaflow muffler, which is still throaty but not like a potato is stuck in it.

early '99, stock exhaust, no muffler:

'03 7.3 with 4" Magnaflow turbo back no muffler, and 6" tip:

I'd like to hear a 5" Straight Pipe with a 6" Tip

lol I paid way too much for my 5" Magnaflow muffler to go hack it off for a sound byte.

(Actually I got a helluva deal on my 5" system, but you already knew that.) :tu:

Maybe :w2:

i did the ultra cheap route.. i just bought a stainless 4" downpipe, some 4" straight pipe tubing from summit racing, and then bought a used stack kit off a member here. i have less than $450 into my whole setup, but my suggestion is if you are gonna do it,

just buy a 4" down pipe from any of the vendors here, and order 2 straight pieces of 4" from summit racing
( Summit Racing SUM-640040 - Summit Racing® Exhaust Tubing - Overview - SummitRacing.com )

and just get an elbow to do a turnout after the cab. may not be the best setup in the world but it will work efficiently.

You can get a good turbo back 4" system for less then 300 bucks... Why dick with the factory system...

I agree!!!!! :rocking:

I third thy notion!:jump:

What is the best setup for under $300? And I love your gauge pod where'd you get it and how much you got in it?

i have a mbrp turbo back 5 inch goin into a 6 inch tip.. it didnt make it any louder inside the cab.. made it a little bit louder outside of the cab.. but holy $hit did the sound quality go way up.. it sounds amazing:rocking:
