  I have a 2014 6.7 Cummins straight piped How much would this muffler decrease the sound I want to make it quieter for over the winter when I goes on high idle in the mornings Thank you

  The MBRP Armor Plus Chambered Quiet Tone Muffler will significantly quiet your straight-piped 6.7 Cummins, delivering up to a 10% decibel reduction compared to standard mufflers. It effectively rounds off the sharp bark of a cold start and mutes the loud jet-engine hiss caused by the VGT turbo during winter high idles.

  My 4" exhaust is too noisy with turbo whine, I need a muffler not a resonator.

  The Quiet Tone is an excellent choice for targeted noise reduction!
