Straight piping a 7.3

[Dave]

I am debating about which way to go with my exhaust straight pipe or muffler

The question ive got is I have heard that in straight piping the 7.3 you lose some low end power. Any truth to that. I do some heavy towing and dont wanna lose power. Is it enough to make a difference I love the sound on a straight pipe

Which way do you all think i should go?

I didn't notice any low end loss at all. When I used my muffler from silverline and its really not much different then a straight pipe looking at it from the outside it was a total letdown for noise. It sounded almost like the stock setup so if your going to spend all that money on an exhaust you don't want to sound stock! In my opinion straight pipe it you won't be disappointed!

go with the straight pipe its cheaper and sounds alot better. hope you like alot of turbo noise. throaty sound but not as deep as a cummins but still sounds awsome on the top end.

I did notice a little low end loss by removing the muffler. Put a chip in and that fixed the loss. I don't believe you tune a diesel with exhaust but when you start changing things the balance has to be met to realize a gain. I kept my muffler for the ends only for they are 5" dia. I welded a chunk of 5" between the 4" ends. This is an expansion chamber that gives the flow a break point to increase flow. This mellows the sound a tiny bit and smoothed out the low end.

i still have my muffler on... love the sound... i like the no muffler sound but not on a 7.3.. the 6.0's sound like a freaken jet taking off but the 7.3( at least the ones ive heard stock) dont sound as good... you hear a lot of surge.. now if you were to get a WW and ATS housing or new turbo then go for the straight..... just my 2c

I just ordered a 5" straight off of ebay for $330 shipped. You can't beat that. Just waiting on the big brown truck.

IF IT'S TO LOUD YOUR TO OLD! I love my staight pipped 7.3, throw on a BB turbo and AFE stage II and let the turbo whistle like crazy...oh baby.

+1 for straight pipe... Your bottom end won't get hurt too bad if at all, and it'll sound just plain NASTY (in a good way)...especially up around 3 grand in a tunnel or overpass..WOOHOO!!

straight pipe it man, its one bad azz sound at about 2500 rpm under load.... its priceless. I have had straight pipes on 2 different 7.3l's and I wouldnt concider a muffler unless I was scared to have one sweeeeet sounding rig.
