Im installing my new 4-2-1 header tomorrow and im just wondering should I re-use the stock gasket or use the one that came with it ? thanks.

 

It's always a good idea to use new gaskets anytime you change anything, but if there was one gasket you could get away with re-using, it would be the exhaust manifold. But, since it came with a new one, use it.

 

Ok thanks sniper.

 

tech I got one that I had to custom to make it fit and it didn't come with a gasket for it. I had to go out and search for one that fit. Buy the way I am converting my LX exhaust system to an EX exhaust system. I bought a universal cat converter from summit racing that I am going to weld in place tomorrow morning.
