i got the zzp header/downpipe, and itseems to be ticking
This happening to anyone else?

 

its just metal expanding from the heat, i have a lot of ticking after putting on my 3" CTI catback plus CA header.

 

Same here, it is completely normal.

 

My stock exhaust does it, drives me nuts ... but i soome wont have a stock exhaust to worry about

 

If it's ticking when shut off it is the exhaust cooling. If it ticks when running then u probably have a leak. Mine leaks when running and the tick is noticably louder when started up cold. No harm done uless u get an engine code(not probable) or it get big enought to be to loud
