Thanks guys will just stick to the regular splice..... also have another question don't wanna spam the section with more posts so ill ask here..... I have an opportunity to buy some dog fight racing chambers and pipes but they are really pricey seeing the condition they are (like new), I've read around and saw theyre like one of the top comapanies In japan I was primarily interested in the tyga pipes but since I have a chance for the dog fight set I don't know .... will I get the same power increase from the 2 sets as the tyga ones are cheaper in price? Will I be paying extra just for the name of a very well know brand on my bike while I could perhaps get the same out of tyga pipes for far less ? And also does anyone know why tyga stopped selling the gp style pipes ?
