Towing - Straight Pipe

[Black06]

Anyone towing extended distance with a 4" straight pipe turbo-back ? Looking for some feedback on interior noise difference from muffler being present. Daily driving is just typically me going to work - no trailer - so I'm not concerned with noise. During towing though, I don't need family YELLING over eachother during extended camping voyages (more than normal) .

Info:
Towing approx. 10,000lb with 3.73 gear.

i've got a 4" turbo back exhaust on my 2005 F250 and it is louder than stock but not much. I rarely notice it

i had straight on my 04 and i never really heard it that much, mainly just when it hits 2500-2700 rpm, then i heard it a bit, but its not annoying like a dodge. i think ull like it!....still missing that truck terribly....

I had a 3.5" straight pipe from the turbo back before I installed my 4" dual kit. With or without a load on the truck at highway speeds you could barely notice it. I found with the straight pipe you hear more of a turbo whistle than a rumble. Interior noise was about the same as my current duals.

I am also thinking of a straight piping my duals.

Dual Delete MDDS927 arrived today. Can't wait to hear it -- straight from the turbo.

Black06, Thanks for the part# Let us know how it sounds.

Installed without issue. Interior noise - no difference. When you put your foot in it, it sounds like a big-block 60's with a glass-pack. Turbo whine is fantastic at all speeds. 65mph on the highway with the radio off, just to hear the turbo spool-up and down.

At idle, I can't tell much difference with/without the muffler (in terms of loud), but the turbo whistle is noticable.

I wouldn't hesitate to advise anyone to do the same. Next test - towing 11,000 lbs.

Thanks for the update. I think I'm going to do mine in the spring.

Please let us know how the noise is towing .
