Hey guys, I helped a friend install his arrow headers today which he got new. He did most of the work but I was there to lend a helping hand. Anyway, he got new OEM gaskets. We torqued down everything per specs too.

Here's the problem. Before putting on all the fairings we wanted to run the bike to check if there were any problems. On start up I kept my hands slightly over the runners to feel any leaks. Holy $^%#( the headers get sizzling hot after only 2 seconds! Anyway... I felt no air escaping. But both of us took it for a ride and there's a buzzing noise coming around 5-6k but its not all the time and he says it never happened prior to the header install.

What does a header leak sound like? Im assuming if it was a header leak it would be evident throughout the whole powerband, not just between 5-6k. Plus, we used new OEM gaskets too. So I'm confused. His bike is still in pieces but the exhaust is still assembled.

We dont have another set of new gaskets so we cant really take it apart and put it back on. Dealer has to special order these things anyway.

Anyone have a clue? thanks
