What people are saying:

The reason I give you guys so much support is because you make a quality legit product that you stand behind, offer impeccable customer support, and basically do everything (both business wise and technically) that I approve of, and would do myself, if in the same shoes. You are running a helluva outfit over there NWP. Keep it up! - Jake from Lubbock, TX

When I received the package from NWP I was thoroughly impressed with the quality of the adapter piece. Install was simple. Definitely a DIY job with basic hand tools. Throttle response is fast and crisp. The butt dyno says that it is making power in the upper RPMs, and did not feel any noticeable loss down low. It seems to be really pulling in the 5K+ rpm which is consistent with the dyno charts that I have seen from NWP. I am impressed with the upgrade and think is a very good bang for your buck that will compliment most other bolt on mods on the market. - Danny from Slammered-Inc (aka GreenGoblin - Turbocharged G35)
