### ⭐⭐⭐⭐⭐ Review
*by J***K on 25 March 2018*

I think its perfect. Very aggressive, loud but not to loud. When you get on it you know it's there but quiet when your cruising on the freeway. I left the resonator on and just did the muffler swap and added a chrome tip. I do hear a little baffling but i can't tell if it's the tip or resonator. All in all a great product and a great sound.
