If your looking for a muffler that is not too loud but makes a V6 engine sound like a V8 this is the perfect muffler for you. The only thing that you will need to buy is different clamps. The one that the box has inside is very cheap and dont work all that well.

Good Exhaust

Other than the band clamps leaking and not even holding the pies together in some spots it's great. I spent 50$ at a muffler shop had it welded up. Now it's great doesn't drone sounds greats at when you get on it. I'd buy it again no question

I received the exhaust 3 days after I ordered it! Installation took around 2 hours! Easy bolt on! The sound is great! Definitely notice an increase in power and torque! Not deafening loud but gives a nice throaty growl tone! Highly recommend!!!

Very good

I am very impressed with the exhaust. Sounds really well and has a lot more throttle response and power with the new exhaust. Very good price to.
