I have the road race header... the dual pipe header. I just ordered the center section from racing beat and now I have a question... where the center section ends and the over the axel muffler section begins is that dual pipe flange or is it a single pipe flange? I was trying to order the gasket to go between the two but dont see it on the page. all I see is the single flange gasket. if its a dual flange were do I get the flange so I can have the local muffler shop build that section for me as you cant order it. I cant find the gaskets either to go between the two

 

In the RB catalog, in the picture of the sp exhaust, the muffler has 2 inlet pipes that collect at the peak of the hump. It looks like one flange w/2 holes in it though.

I am thinking of getting the road race header and collecting into one presilencer at the muffler.

 

You can get that part from racing beat. All the dual stuff you can buy separate and weld yourself. Look at there web site. If you need help and can shoot me a picture of what you have I can help.
I have the Roadrace SS header with the 6th port provision and the 02 bung.
That dual header blots up to the streetport Presilencers (long primaries) into a dual tube muffler.
Here is the complete exhaust and then the header.
Do you have the header with two holes at the flange or one?

 

The part # is 16314 from RB. 81-82 dual tube style muffler gasket.

 

I have the road race header... dual pipes all the way back... so anybody know what it sounds like with just the presliencers?

 

it has a deep sound and very loud. it couldn't be run on the street without the muffler. it's very surprising how the rb muffler quietens it down. if u live where loud exhaust is an issue, the complete sp setup is the way to go.

 

anybody have the muffler section they want to sell
