well I pulled off the muffler today and put in the piece of pipe, its pretty awesome its extremely loud though and very raspy, reminds me of a glasspack overall length of exhaust was downsized by half foot pipe was 2.5"D 18"long 1/16" thick, although when I got back home and checked to make sure everything was hooked up the pipe came loose from where it mates with the original exhaust so maybe thats why it was raspy because I could feel a plentyful amount of exhaust escaping from where the two pipes mate

 

mines strai piped it set off car alarms lol

 

All i have is 2 2.5" pipes ending under the cab and i don't think its that loud... Is my hearing that bad?

 

I was driving my truck through town and it was turning heads lol it seems like the truck has a little more "oomph" although that could just be my foot constantly on the floor because I love the roaring sounds coming from the straight pipe lol, now look what I've done I'm going to get even worse mpg now hahah

 

Otahyoni,
yup.probably due to liking things way to loud for too many years lol.
even the straight piped turbo idi i listen to on youtube i can tell are more than id live with.

hey powerstroker,
did you ever check my exhaust out? i think i did it before you came along.take a peek.video of running there too:

u should hear mine wide open sound like steel drums!!!

 

I've never had an N/A IDI with a straight-pipe but I've had two 7.3L PowerStrokes that were straight-piped, been around a lot of Cummins with straight pipes and my turbo IDI sounds WAYYYYYYY better than any of them.
It's not loud until you stomp it to the floor and even then it's not loud inside the cab it just sounds good. Someone brought up on time that the latter IDIs are better insulated/sound deadened so that might be the reason for the quietness in the cab.

 

WHAT??? DID YOU SAY SOMETHING??? I CAN'T HEAR YOU!

 

ya gotta wait till I get up to speed if you want to be heard sayin somethin in my truck lol

 

A Turbo makes all the difference in the world to exhaust noise levels over a N/A.

I took pictures, currently being held up by wire coat hanger lol

 

thats the best type of tie down

 

Totally.

I was running only a downpipe on my 7.3 DI, no muffler, no cat, and you still couldn't hear the exhaust over the sound of the engine clatter. The turbo eats up pretty much all the sound.

Baling wire gets you a ticket in Maine ...
