The cheaper top speed exhaust sounds like it rattles when you decelerate.
If you watch the videos, it sounds like a metal grind on downshifts etc..

When I get on it its loud in the cabin, but when im just driving normal its not bad at all. I do have some GTmat soundproofing in the truck so that does help alot. Drone is very minimal but I was expecting to get some drone after I installed the HFC.
As for metal grinding sound on downshifts none of that here, just some slight rasp and the typical "hiss" which is completly normal with our engines.
