It is very weird. After I put my XS headers on I would get resonance, BUT its only for the first 10 min after a cold start. After that I get ZERO. Why do you guys think that is? When I do get resonance its between 2500 and 3000 and it sounds horrid. After a few min its gone.

The only thing I can think of is that after it warms up all the seals seal up better. What do you guys think?

 

thats not uncommon. it has to do with vibration. you might have a leak somewhere

 

if there is a leak why does it stop after driving for a few?

 

Please repost in the XS thread. All complaints about them should go in there.

Thanks
