Drove the R/T off the lot today, proceeded straight to muffler shop to straight pipe it. Had the mufflers and resos deleted and OMG I have never heard such a beautiful machine. Extremely loud, aggressive, throaty, and very intimidating. I can't believe it would sound that good. Recommend this to any. Drone is not bad either, it's worse if you have flowmasters (previous challenger) I'm just exited and I wanted to share. I am so glad I did the swap!!
