I know they had the dyno and a video, dont know if they still do. I know that the benefits of running true dual beat out the disadvantages...



But to answer this guy's ? I would just run the headers and not worry about the cat...

Agreed

Sounds good to me. I guess if I have too i'll wire the Aux ports open.

Yeah, don't do that. The thing with the RB silencer is that it has a C pipe in it for aux ports activation. The lower half of the c sits down in the exhaust flow, so that exhaust gas actually flows up into the pipe, and opens your aux ports.

What do you believe the advantages are? I feel there is ZERO reason not to incorporate collected scavenging, but thats just my belief. I'm honestly curious to outside theories....

... and now it is all good. Replaced the olde exhaust manifold.



Got Tony to help me out wit the labor.





Purrs like a kitten now with a good throaty sound.



Thanks.
