Hi All,
My 4 into 4 exhaust is pitting really bad and I have a spare 4 into 1 Kerker that will fit. Do the stock exhaust collar not fit on the Kerker, the Kerker's have the flange built onto the header and the collar does not wrap flush around the pipes. I worried that w/o the collars the headers are not seated centered into the exhaust port on the engine.
Thanks!
JT
