I have an 02 F250 with a 4" straight pipe exhaust. I love the sound i get out of it but i want it louder and i have heard alot of 7.3's that have that big rig sound to them. How could i make it a little louder and maybe get the big rig sound. Aeroturbine?

 

I have the aeroturbine with the internal resonator and it soungs great but I know it is not what you are looking for if you want it louder. If you already have straight pipe with the muffler delete the only way to make it louder is to shorten the pipe, dumping the exhaust sooner and closer to the engine.

 

Oh ok. well i live in Texas and we have to have the muffler. so i still have it.

 

I just dumped my exhaust before the rear axle with a muffler and it sounds pretty wicked when your on the skinny peddle.

 

im thinkin about cutting my muffler open and guttin it, im not sure if it will be louder than a straight pipe or not.

 

you have a magnaflow 4" w/a muffler, the muffler should be a straight threw style muffler already.

 

it is!! but the center pipe is perferated (spelled wrong) and wrapped in sound deadining stuff. it is super quiet at idle and not that loud at WOT.

 

That makes sense.

 

Time for a 5 inch exhaust set up coupled to some stacks. That will be a tad bit louder...

 

You could weld a peice of pipe inside the muffler so its straight piped and looks good for inspection

 

Thats what Im talkin bout, really fool Johnny Law!

 

its all about perception

 

I was gonna rep you, but got arrested.

 

Hahahaha yeah here in midland all they do is look under and say yeah its there and go on with it. that is pretty clever about puttin the pipe in it. Going 5 in you wouldnt be losing to much back pressure will you?

 

im running 5" to a stack no issues
the down pipe is still 4" so ur good on backpressure
