Just noticed that my greddy sp catback sounds louder and dirtier. It used to give me nice clean sound but it sounds louder and shietier...... what can i do? does it need some kind of cleaning somewhere? ive changed my oil on time and all....

thanks,
Tae

 

Maybe an exhaust leak...

 

hrm, does the exhaust packing on cars ever wear out? Ive replaced my packing on my drit bike like 2 times.

 

I does a little but it's seems minor and very very gradual...

 

what kinda sound is it making?

 

Is your GReddy still under warranty?! Or do they even come with warranties?! I dont see how the oil has anything to do with it and i doubt you have to clean and maintain the muffler...Maybe a leak, does it have a hissing or repetitive gunshot type of sound (ba ba ba ba)...If so, get it checked out...
