I previously had a hellcat and now got the Redeye and when I started it up it sounded SUPER quiet. My old hellcat sounded way louder stock than the redeye. I just changed the exhaust and it still sounds very tame. Does anybody have a similar experience?

Did your old Hellcat have the cats changed out or not? Remember the recall?

Nope I had it a couple of months and traded it in. I never got any recall information.

My RE seems louder than my HC did. Angrier.

New cars are generally quieter until the parts break in.

My RE is noticeable louder than a Hellcat.
Especially with clear cats now.

Make sure your cats are clear, they can internally bust down. Rare, but it happens.

Indeed. I noticed this on my Scat, too. Took a couple thousand miles to open up.

Yep !!! once breaks in gets louder ....

What is the reason for it getting louder after break-in? Pores open up on cats?

 

[Xylander]

Generally, the pipes have bends and seams in them. As they break in, carbon builds up and fills in the gaps and what-not in the pipes, which allows for a smoother flow. In addition, the baffles in the mufflers and resonators also get carboned, which lowers the tone somewhat. This makes it seem like it's louder as lower tones travel farther and you hear different levels of sound through the interior.

This.

My wife and I both thought the 21 Redeye we got was quiet compared to my 15 hellcat, however as time went on and parts broke in I'd say it's about as loud now.

I cut out the mids and replaced them with Vibrants and then cut the rears.
