Stillen Headers + Berk HFCs self-install report

Awesome wstar!

The rasp you're hearing is most likely from the HFCs, and it's sort of par for the course. You want the increased horsepower, but it will add some rasp (although seemingly far less than previous year Z's).. Test pipes take that to another level..

But it will absolutely not hurt to run everything through and make sure their are no leaks, that will definitely add to the noise, and not in a good way.

The cat-back can take some adjustment, and a lot of people have asked us why there is adjustment in our exhaust systems. The answer, unfortunately, is back to Nissan, in that the stock exhausts don't always line up, and rarely are on spot. The cars are just built slightly differently. Most people don't notice because they aren't staring at the brand new part they just installed, the entire car is new. We go the extra step in allowing for minor adjustments to compensate.

Congrats on the new exhaust! Glad you're feeling the results others have been documenting..
