If you dont recall I just bought a mac y-pipe because my old one was
cracked. Between fighting with the old flange studs and all I've given up
hope and now just want new headers. Beside my car is what it is. Is it fast
yes but it no top fuel dragster so headers will give me a bit more power but
this is not my main concern. On the other hand Mac claims that there headers
for the third gen will not work with there stock replacement y-pipe. But in
all ad's and in there catologue the y-pipe that comes with there headers is
exactly what I just bought. So my only guess is that they are eaither lying
trying to get me to buy the header y-pipe combo or the flanges are the only
thing that is different.
