The N1 Evolution Extreme is based on the proven performance basics of the N1 muffler which emphasizes optimum exhaust efficiency utilizing a straight-thru layout design. Equipped with an internal hybrid silencer uniting power and free flowing characteristics with effective functional sound resonance. A newly adopted muffler tip completes the tail end of the exhaust that serves both purposes of function and form. Constructed with a light weight titanium material rolled and riveted onto a double pipe structure which acts as a diffuser enabling temperature reduction, meanwhile retaining a sporty heat gradation appearance.

rmk Staff Notes: 
Beautifully crafted, the fit and finish of this exhaust is what you expect from an APEXi product. The overall sound is nice and deep, not overly loud, and we did not notice any drone during cruising. The dual muffler setup is interesting, and allows for use of the OE exhaust valve function which we like. The difference in sound level is not dramatic but it is noticeable. One drawback to this exhaust is that it is NOT a true 3". The first flange to connect to the front overpipe is reduced down. We feel this is not an issue unless you are planning to go for significant power upgrades as this would be a potential choke point in the exhaust. We feel this is a great exhaust for someone who wants to retain the OE exhaust valve function, and is planning to leave the engine and turbo relatively stock.
