I have the chance to buy a bikeman pipe for my 2011 e tec 800 for a really good deal. just wonder who has ran the bikeman y pipe and single pipe? did it make much difference? if so where did you notice t mot low?mid?top?
I had a ceramic BMP y pipe and pipe with a specialty can on a 2014. Quality was good but light and thin. They say to run lower rpm, 7800 i think to take advantage. Didn't really notice a power gain but ran clean. Stock got bent, replaced with aftermarket.
Stock system gives the best performance throughout the entire power band. Some will increase bottom and mid but decrease top end, some increase mid and top but decrease bottom end. Ran the stock system on my ported engine ad stock engine and it worked the best IMO. Stock made best HP#’s on dyno for the ported engine but that will also very with porting.
