well the service engine light came on my car...i have the slp catted x pipe. and i have a slight leak on the left side...the leak is cause there is a gap from the header to the x-pipe...and i was wondering if this is normal???
on a mach 1
i dunno about mach1s and the 4v but on our cars (2v) we dont have a gasket on the driver side between the manifold and x-pipe... im facing that same problem with my slp x-pipe
