Here is a complete thread dedicated to all K8 Busa Exhaust, hope this helps? it covers most of all the main exhaust companies, if any are missing ,please let me know so i can update the thread with new current 08 exhaust with pics please.need some help can't make up my mind what 4 into 1 pipe to go with, yosh r 77 cabon or ti force carbon
My test mule is still trying to get some break in miles with this cold northeast weather, so no testing yet. He has the Ti-Force 4 into 1 380 MM as well. Would love to do a back to back test same day. Maybe shortly.how much hp will i get from the 4 into 1 ti force,.. over the yosh 4 into 1, and is there any advantange with the shorter ti force pipe
I agree, also some shops have dyno's and lie their azz's off and have bloated and inflated numbers to never be repeated again anywhere in the country. Its absolutely impossible to gain 35 HP from a pipe and a tune but some are saying its so.in the end it will all come up to who tuned the bike, how, mapping and dyno the maximize the exhaust, the TUNER is key!!!!! some shop may have a dyno, but do they know what they are doing?
