help with z400 exhaust

[Leo]

ok im either getting a Duncan Racing exhaust or a Yoshimura.
this will be the complete thing with the header and everythaaaang.

the duncan racing one i can get it for 549 with free shipping and a jet kit to tune it(great deal imo)
and the yoshi is gonna cost me like 495 without a jet kit. shipping should be free also. the model number for the yoshi is the RS3. the duncan racing i dont think has a model number, they only sell one pipe for the suzuki's from what i heard.

basically just trying to figure out which one i should get. ive heard the duncan's on 400ex's and shit and it sounds deep as fuck and nice, which is why im leaning towards that one. just wondering if anyone has had any of these.

i used to have a yoshi pipe on my z400. i loved it. i never heard one of the duncan pipes in person though

yoshi ALL the way homie

the yoshi pipe thats on motosport gets most of the power towards the end of the gear, id rather get if front/mid range. it was supposed to be made for track users not trail riders. im calling the company selling the duncan tomorrow and hopefully ill have a pipe by this sunday
