Don't they use 14GA. tubing? Much better than others.

I've had an Accurate Exhaust on my Charger for about 20 years now with zero issues.    Had the Hemi High flow mufflers on there for a while.

These are all with stock HP cast iron exhaust manifolds

Later switched to the Ultra-Flo's by Dynomax

Thanks for your reply good to hear zero issues with the system the Hemi hi flow sound a lot angrier & the ultra flo's have a bit more drone too them.Which one did you prefer ?

Good videos Chris

I want to get the Satellite a little more rumble. and have been leaning towards the UltraFlows. You sold me

I wonder how much difference there is in sound
from the Ultra Flows to these

My SuperTurbos had a pretty bad drone at a certain RPM, UltraFlos -> no drone. Definitely more rumble, but I was pleasantly surprised that it wasn't too much. I used the same tti exhaust from the x-pipe back on essentially four different 440's, and the engine build itself made by far the biggest difference. Stock based non-HP 440 was pretty mild with SuperTurbos but there was the drone I mentioned. Same 440 with Ultra Flows was more rumble and seemed a little deeper. Same exhaust with smog 440 was very mild, almost too quiet. I apparently offended a lady at how quiet it was idling at a stoplight. Rebuilt 0.030" over 440 with aluminum heads, solid roller cam and 10.2:1 compression is loud all the time, to the point I'm sure all my neighbors hate me
