I did this to my 2015 Mazda 6 about 3 months ago and it’s been one of my least expensive mods with the greatest benefit. For those of you looking for a more prominent exhaust note without paying those Corksport prices, consider swapping out your OEM resonator with a Vibrant one!


Vibrant 2.25" Bottle-Style Resonator: https://amzn.to/36VqJF7


(taken from video so may look low quality)

Pros:
-you can drop about 10-15lbs with this small change
-louder and deeper exhaust note
-retains a clean note without rasp
-one of the least expensive exhaust mods/options for the 6

Installation:
Welding is required for this modification so most likely a local exhaust shop will have to do this, but it costed only $50 and 30 minutes so it's not too bad especially for the result!


Sound Test:
Because of how hard it is to go off of just someone’s word I recorded both setups before swapping the resonator. In my opinion there’s a clear difference in tone: both deeper and louder. The change is only more prominent when driving and getting higher in the RPMs.


Let me know what you guys think and if there are any questions don’t hesitate to ask them!
