Aaron Excell (Excell Mororsports) has come up with an extermely dandy
replacement header for the Yamaha Vector–all stainless, with great
airflow CFM increases from midrange to top end, and similar HP
increases even with stock quiet muffler. I will post the results
this week. Also he had a new oval center outlet muffler for the Apex,
we dyno’d stock and with his muffler, added airflow CFM from
midrange to top end with minimal dB increase.
