(Taking Comments On Which is Better the Yoshimura ATV Pro Series Full System Exhaust (titanium) or the
Slip-On Aluminum One)


Anyone Know the HP difference between the slip on and the full exaust? Thanks!



Also Taking Comments On How people like there Yoshi Full Exaust Pipes And Slip On's


This Is For A YFZ 450!

 

come on someone has to know something!!

 

i got a titanium trc yoshi pipe. getting a slip on is practically just for sound difference and looks, practically. The ful system of mine has a bigger header pipe, allowing more compressed air to come out through it, making a crisper, deeper sound and more power to come out of it. but also keep in mind that u have to rejet. i recommend using the dyno jetkits for rejetting. the yoshimura trc titanium exhaust full system is virtually the best for a yfz450. Its light, durable, and provides very great power, but the only reason it wasnt one of the contendents batteling against other yfz450's exhaust was because it was too loud and was expensive. but if ur a true racer like me, the price is reasonable and loud sounds are perfect!! second was the curtis parks exahuast system, would have been number one but it was to heavy, pure stainless steel.

so what would you say the horsepower gain difference would probly be?

 

for a slip on, ull probably get about 3-4 hp and with a full system, ull probably get about 3 hp in the mid and 4 hp gain in the top end, total of about 9 horse power gain. more can be gained by rejetting and removing the air box lid off.

 

would you recommend a Yoshimura ATV Pro Series Full System Exhaust ( TRS )(titanium)?

 

YES, BUT Y WONT U GET A TRC TITANIUM YOSHIMURA FULL EXHAUST SYSTEM. IT IS THE NEWEST ATV EXHAUST SYSTEM MADE BY YOSHIMURA? IT COSTS ABOUT 745 FOR A YFZ450 BUT IS WELL WORTH IT. IF U LOOK AROND ON THE WEB, U MIGHT FIND A TRC FOR MUCH CHEAPER. THE TRS IS THE SECOND BEST IN THE FULL LINE OF EXHAUSTS FROM YOSHI.[img]i/expressions/face-icon-small-smile.gif[/img]

also whats the difference between the non-carbon fiber and the carbon fiber pipe besides the price? lol

 

yes, it is the pipe i am talking about. its the newest and best one. the carbon fiber one is just the same as a titanium one but with a carbon fiber material wraped around it just for looks. getting the carbon fiber one just adds a lil bit more weight to it because its just the same exact thing as the titanium but a carbon fiber wraped around it. naw its kool, dont worry bout asking too many questions.
