 Re: what does high perf head and exaust do for ya
Not sure about mud buddy's but I Have a 36hp prodrive. I was turning up about 3900 RPMS while running before I had my work done. Now, I can turn up 4500 if I let. With 4 people adults, I dont feel any hesitation getting up and running now that head work, exhaust and new carb is done. Hope this helps !!!!!!! Extreme V-Twin did my work....

 Re: what does high perf head and exaust do for ya
Perfomance exhaust lets the engine breath better- more air flow in with the Mikuni, more airflow out with high flow exhaust. Stock exhaust is giving backpressure that is causing you to not get full advantage of the Mikuni kit. Crossover is a better choice than duals in my opinion.
Head work gives a good seat on the valves (the stock are horrible- they need to feed those guys in the factory more rice). Having the valve springs shimmed lets you run higher RPM without the valves floating. Decking the heads increases compression.
All in all your low to top end and load carrying capabilities will be increased. More powere through the powerband.
