Strange sounding exhaust

[MAGNUM351]

I have an '08 f-350 crew cab long bed, that i did a dpf delete as well as a cat delete. I left the remainder of the stock exhaust including muffler and tail pipe. I am also running the H&S minin max. The exhaust sounds like a jet engine or a hair dryer as some have reffered to it. I was wondering if there is anyway i can get rid of this sound. I have heard of dis connecting the exhaust pressure relief valve on late '90's trucks. Is that something i can do on my truck? Would changing the muffler / tailpipe help? i do not want to run with no muffler as i dont want the truck to be too loud.

any help would be great. Thanks in advance

You can thank the twin turbos for that sound and about the only thing you can do is put a muffler on. Since you left yours all stock after the dpf I dont think it can get any quieter. These 6.4 are reletively quiet just be glad its not as loud as the 6.0 if you dont like noise

I have a 5in straight pipe on mine and it still isn't very loud. It does have the hairdrier sound at idle if you stand by the exhaust. I've heard mixed reviews of the aero turbine muffler knocking some of the hairdrier sound out, but I haven't personally heard one.

Dude, dont monkey around with any valve or anything. The turbos make the noise. Either get used to it, or put a muffler on it. Magnaflow is the way to go if you want one.

just make sure the muffler has packing in it (magnaflow, etc.)

even a small dynomax "bullet" will cut down on the turbine sound, whereas a non-packed muffler won't.

I love the sound of turbine in the exhaust

This. The trucks sound incredible. There are two turbos moving some serious air. Get a 6.0 if you want more of a car sound.

I don't want the truck to sound like a car,I just want to cut down the hair-dryer noise down,the sound of the turbos is not the problem,want some deep tone,I'll try the magflow muffler, thanks

I run a 4" turbo back straight pipe and it has plenty of deep tone. Esp when you put it on the floor!!
