Very easy to install once the stock downpipe is removed. Sounds great and power increase is noticeable. Sound clip included. https://youtu.be/SykUnwspCPo

Advantages: Noticable power increase

Disadvantages: If you have a Resonator delete or muffler delete it will increase drone. Best to pair with a catback exhaust.
