AKRAPOVIC KAWASAKI NINJA 400 18-23 STAINLESS STEEL OPTIONAL HEADER
Initial quality looks great. Planning to use track days. My existing SC Project Can does not fit. Have to buy Akra muffler.

Great product!
Well worth purchasing the full system, really makes the 400 appear more aggressive and gives it a total makeover while sounding great too!

Bought these to give my bike that little extra “boost” and “growl” Does not disappoint! Installation is a breeze and the fit is perfect.

A must have if you have just the slip on
Got only the slip on when I got my bike. So glad I got the header. Definitely feel the difference in the ride and sound. Price and free shipping can’t be beat. Thanks STG.
