Exclamation Cut down the hair dryer sound!

Hello all, being as I am in a state that requires diesel smog every two years I feel that my recent cat/dpf delete might be a little too much. I really want to cut that hairdryer sound at idle down by about half! It sounds like a darn jet plane! If i lived in the country i would love it but I live in the suburbs and don't want any more extra attention. Is there anything out there that I could just weld into one of the delete pipes that will resemble the cat such as maybe a resonator? Something that will cut down on the hairdryer sound at idle and if i am lucky cut down smoke. Not so much worried about the smoke. Thank you

I'd be more worried about attracting attention from the smoke than from the sound. I'd say just don't pull up and put your tailpipe in a cops window and you shouldn't have any problems!!

I have the elite egr delte w/wastegate, plus I replaced the silly lookin stock exhaust tip with a single tip and cut out most of the woosh sound. Too bad you have to keep the emmisions hardware.

You could add a larger muffler or resonator to the exhaust.

Maybe its just me, but I've always attracted WAAAY more attention with black smoke then the sound of my exhaust...........either way, like Jeff said a muffler is probably your best route

Ok, so basically have two mufflers? Makes sense. Will the added muffler cut down on smoke too?

No added muffler will not cut down on smoke, you could get just the dpf delete pipe and leave the cat I believe

you need a packed muffler to cut down on turbine sound

if you want to roll stealth, put the cat back on and hollow out the DPF

I don't see how the mufflers dont get clogged up after some time with all that smoke blowing out. I looked at my exhaust tips and they look pretty caked up after only a short time of being deleted.

If there is no restriction and air flow is always positive, you don't have to worry about clogging.
