So I have the F-sport exhaust 2nd gen? (with the logo) and I've notice lately that the right side seems to get dirtier faster than the left side. I've checked for leak and all possibility and everything seems normal. Anybody else have the same 'issue'? or want to chime in?

Thanks

 

Because the right side is a straight pipe. Left has a resonator
