Will straight pipe cause more cab noise 6.0 PSD

[smuesse]

I have a 2003 F350 Dually FX4 King Ranch with the 6.0 Powerstroke and the Torqshift tranny. I would really like to put a straight 4" pipe on it but i dont want to loose the quiet cab. I had a dodge before and it was loud and annoying. How bad is the cab noise from Straight Exhaust?

Not bad at all. Its more whoosh and whistle than anything. U can't hear it much unless windows r down and radio off. Its everyone else that can hear it!!!

welcome to the site

the straight pipe shouldnt cause anymore cab nouise as long as yopu have it exiting in stock location

I plan to run it out in the stock place. I see lots of kits on ebay that have a straight through muffler. Would the Straight through Muffler be better? Any one have a suggestion on a good place to get an exhaust kit? I want quality but not have to pay to much for lust a piece of straight pipe.

I have a tendency to believe that my straight pipe is much quieter than it really is. My wife (and anyone else that has followed me) is quick to inform me that it is anything but quiet outside the truck. Inside the cab, you have to really be romping on it to raise the noise level much above stock levels.

Even with the right rear window open, it's not that loud or annoying. I have to slide the rear window open to really hear it well. Of course, when I am pulling a heavy trailer, it tends to bark a little louder than normal.

If you go to you tube you can hear sound clips

The only thing I noticed when I had mine done was Like a smooth mellow roar at higher rpms other than that no diff. than stock

Is there really a big differance in performance? Some of the Dyno graphs i looked at look like the factory exhaust actually has more power in the low end and it stays the same until about 2800 RPM. I just use mine as a driver, i dont really pull much. I guess im trying to figure out if its really worth spending 300 bucks on it.

if you plan to ever do performance mods then its worth it
