Deeper growl

Reviewed By John C (Mill Creek, OK) Reviewed for a 2014 Dodge Challenger —11/4/2015 2:59 PM

I wanted something to compliment my CAI and to gain a little more growl factor for my ride. I would not recommend this mod for everyone. I drive my challenger for the pure fun of it and a the added drone isn't a problem for me.
