Howdy!

I have a long-primary setup to fit 1st Gen. consisting of the two pipes with presilencers and the rear collector piece which connects to the muffler. The system is custom-fit and has hangers for the pipes. All that's necessary is a RB uncollected header and to either weld or flange the muffler to make it complete. I would like to trade for a 12A RB header in good condition with a mini or full-length presilencer to go on my '80.

If I don't get any takers I'm going to cut one of the presilencers out of the long-primary system to complete my short-primary system, but I thought it would be kind of a waste to do so, what with the long-primary systems being so expensive to buy. If you are running a street-ported motor, you need this setup! -WG

 

Anybody? This is a good deal! Don't make me butcher this system for a lousy presilencer!
I'll do it, I swear!!! LOL -WG

 

Here's what I have minus the Header and the muffler.

 

Why are you moving to shorties? Isn't that less low-end torque?

 

The short-primary system moves the torque peak DOWN, actually. The long-primary system is most effective on street-ported motors, and then the gain is in the upper range. I'm working with a stock motor presently. -WG

 

Hey I have a unused streetport 12a header....

 

Are you talking about an uncollected "road race" front section?

 

How much? I might be interested in your RB setup.

 

Bump.
