Glass Packs

I agree to that. Maybe some folks like " Ground Pounding Sound"? Possibly some folks have a limited cash flow, and just wanna close up a chapter of their build? That being said, it's nice to hear your mill, when ya get older... instead of the Much-loved sound of a Mopar THUMPING! There are better performers, that allow you to " hear" your engine, these days...

I'll tell you this, on my 340 I run Doug's headers to 300 Cell metal cats to Dynomax Super Turbos out to stock tips all on a dual 2-1/2" dual exhaust and its borderline too loud in the car with the windows up and the 2k resonance (drone) is murder. I run a full interior too. I have a set of resonators to put on this winter if I can.

To me glass packs would be a 1/2 step away from running nothing unless they were 10' long. Do a utube search, while not 100% accurate it will give you a idea.
