any headers that will bolt on to my borla y-pipe?
any ideas were to get headers to bolt on to my borla y-pipe?
are 1 5/8's shoty headers a waist of money or do they flow well for a bolt on only engine?
thanks,

I've heard some good things about the macs. Someone on the board problably has them and will chime in soon.
I think mids are popular because they flow a bit better than shorties and if your car is lowered there won't be clearance problems.

One of the main things the coating does is keep underhood temps down. There is also a performance benefit related to how different temp gasses flow. Someone with a little more knowledge of that would need to explain it though.
I have read enough on this site to know that you should NOT....at all....buy headers WITHOUT coating them.
There are several benefits to coating. Someone who knows more will hopefully chime in soon.
You can run a search and look up anything and everything about headers. That may be why these guys haven't chimed in. Some of them have already answered these questions ad-nauseum in previous posts.

I have considered these myself, seems like the best deal, I am told they are neraly the same as the Arizina speed and marine headers. Ive heard they perform well but have terrible spark plug access.1995 Z28 Convertible, 350ci LT1 73K miles M6.
