I just bought a 2012 dodge 6.7HO cummins 3500 dully. And I was wondering if you could just put a pipe on it so the truck would be a little louder that what it is. Or would I have to do a tuner and a air intake? Because I know when you do a tuner it cancles your warranty.

 

The cold air intake may let you hear the turbo spool more. It shouldn't void your warranty but you can't alter the exhaust or the emission system and that's the only way to make it louder.

 

Thanks for the reply.
