Best headers for the dual cat set up?
I want to get a set of headers for my 90 trans am but with the dual cat set up its seems they are hard to find. The previous owner installed a very nice high flow stainless cat set up so i would like to keep them. I see Edelbrock makes a set, but does anyone know or tried any other ones?
Thanks!
Thanks!

Re: Best headers for the dual cat set up?
you get them from "the man" himself... he who posted those.. "Dyno Don". the only 1 3/4" headers on the market, with ball and socket 3" flanges, 2 1/2" dual pipe. Send him a PM.

I run Edelbrock headers with dual cats and a 3" SLP exhaust. Works great so far.
Dyno Don headers have great reviews here...will add them when I swap the cam and heads.

Re: Best headers for the dual cat set up?
One more vote for Don's headers. Quality is top notch and everyone that looks over my car is amazed that I found a set with the 1 3/4" runners. No numbers yet but with my HSR, Don's headers, T-56 and 370 gears on a stock motor its hard to keep it planted and straight until i hit 3rd in street tires.

Edelbrock TES dual ypipe headers. They make some for single ypipe too.
