05rr header leak after installing new Arrow headers with gaskets

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

Buzzing noise could be the springs vibrating and hitting something. My yosh system had springs with a little rubber cover around them. Just a possible cause of your noise but I don't think a leak would sound like that.

An exhaust leak is a very distinctive sound. If you've ever heard a pulse jet, it is similar in sound.

I agree with it being the springs vibrating. At different frequencies over the RPM band, they'll make different noises.

at first i also thought it was an exhaust leak but it turns out the springs that hold the tubes together is what causing the noise to appear at a certain rev range.

thanks everyone. We are gonna put this thing back together in a bit. I guess feeling no air + the fact that it sounds good is good enough to figure that its not a leak. I got the same headers and no buzzing...yet. Watch, it'll happen now that I jinxed myself *$&)

If you look for a noise or something that sounds "odd", you'll usually hear something that is always there, just think "oh ****". I see it all the time and it's all just our minds messing with us.
