Is there anyway to make the exhaust sound a little louder?

Okay, I realize im going to get flamed for this, but here goes. Im new to this forum and have got ask....

I have a stock 2013 Ram Cummins. Its my first diesel and I love it, with one exception, I wish it sounded at least a little more like a diesel, just a little bit louder like a diesel should.

Back ground, Ive heard from 2 unconfirmed sources that the next generation of smog checks will be able to identify if a computer has been flashed/burned or modified and will fail a truck and/or fine for modification of SMOG equipment. Similar to how the dealers can tell. Unfortunately I live in this Utopian state of California. I was very close to installing a programmer and deleting the EGR, DEF and the rest of the BS. Not for power gain but for reliability. Since then, I have scrapped that idea until I know more whats coming down from the EPA goons. At the moment I have accepted having to keep the DEF, EGR and the rest of the SMOG crap.

My question is: In an effort to get a little more sound (more than a VW rabbit), is it possible to hollow out and/or install a pipe sleeve with-in the cat? Would the system still work with out throwing codes? I only want it to be slightly louder, leaving the CAT in would allow it to pass visual. It appears that there are only 2 sensors on the cat???

Does anyone know if the "new generation" smog checks will actually be-able to identify these mods?

I swear Ive searched all over this thread, Im sorry if this info is burred where i couldn't find it. Im new to all the new "diesel Tech" so Im sorry if this is a stupid question..

Thanks in advance for any advice.

You go for smog checks right? Do the plug into the obd port and check the readiness monitors? If so gutting and putting a pipe through the DPF will trip codes and your monitors wont set and you would fail

Correct. Then you might throw catalyst efficiency codes

Remove all sound insulation in the cab, and especially on the firewall. That way you'll have more noise, but people around you won't.

Maybe if we start telling people that the brain is an app, they will start using it?

Jimmy N you pegged it. If you want more noise that's the answer; just don't make me deaf too.

Um, excuse me sir. This thread is strictly for people with pre-13 trucks to suggest irrelevant things to a guy with a totally different emissions system.

How about SIMs? Just get some SIMs!!
