The Mugen 4 into 1 header is among the finest of 4 into 1 designs for your Acura/Honda. Mugen headers are tuned to optimize specific engine power bands. With the 4 into 1 design, you will find the most horsepower and torque gains in the higher RPM range. All Mugen headers use TIG/Gas welds, which are superior in strength and finish compare to other products on the market. Also, instead of a cold bending process, which produces a tubing size reduction, Mugen uses a costly sand bending method for uniform tube dimensions. All Mugen headers are hand-made and comes with OEM gaskets and mounting hardware for long lasting trouble-free performance. Note: Prelude's utilize the 4-2-1 design.
THE B16A 4-1 HEADER IS VERY RARE. WE HAVE ONE LEFT IN STOCK!
