Installed this on my Nitro 3.7l. Easy to install with just a few hand tools. Adds the slightest change to deepen the sound. The most obvious impact is the throttle response. It's a 3.7, it's not going to your local track. But it definitely is a bit peppier and a lot smoother when it's needed. I would highly recommend this to anyone looking for an increase in gas mileage and improved response.
