Here is a "custom" universal header kit for all engines with 3/4" NPT fittings. (not to be confused with 1/2" NPT which actually measures 3/4" on the outside diameter) This "deluxe" kit includes 8 (YES! 8!) 90 degree pieces with enough little threaded pieces to join them in harmony, 1 piece 45 degree fitting, 1 piece 4" straight pipe, and a gently used Briggs industrial muffler with 45 degree turnout. This is the ultimate kit for the "do it yourself'er"! Grab your pliers and you are ready to go hit the trails! Not dangerous enough for you? Add teflon tape for a special noxious off gassing that is sure to give you a buzz! This set up flows well and works in most minibike frames. If a new header is in your future, I've got the kit for you! If this is sold before the end of today, I will include a set of FREE steak knives (addl shipping and handling applies). Get this now for only $39.95...and I will ship it for FREE!
