Product Description
ARC's header and muffler kit for the AKRA/WKA clone Box Stock class. Looking at the picture above, it is easy to see what sets ARC's header apart. The flange is funneled into the header pipe so exhaust gases flow smoothly out of the exhaust port. Contains a DJ-1138B CNC port-matched header, RLV-4117 "Mini 91" muffler, Pre-bent steel brace and two clamps.
This header is designed to fit the Honda/ Clone, may not fit or may require modification for Predator engines. Call and talk to one of our techs if needed 1-800-521-3560.

Header pipe muffler
Fast shipping, good quality. I did have to clean out the bolt holes with a few passes of a round file but it fit.

Box Stock Header & Muffler
I put this header on my BTX200x mini bike and it worked out very well. I was not sure if it would interfere with the frame, since this is mainly a header for karts, but it is perfect. The header stays tucked inside the frame and exits next to the rear tire. I had to trim the rear fender a bit but that's OK. It is a little louder than the stock box shaped exhaust, I did not want one that was too loud. I would have kept the stock configuration, but the stock exhaust interfered with the frame after upgrading to a TAV 30 clutch. I had to raise the engine 1" for the TAV to work. So I'm very happy with the header and the service from ARC.

the machining and fabrication of this exhaust is awesome

Great product
Great header and muffler. Only problem is the brace had to be bent to fit a Predator Hemi. Would be nice if ARC made a combo specific to the Predators.

ARC Header and Muffler Kit clone Box Stock class
The header was well made and very functional. I did notice the quick milling on the inside of the exhaust flange. I had to put in some extra work to smooth out the port. In all the header and Muffler fit very well. The price point for this product makes it a good buy. I would recommend this to others.
