is there any headers out there that will bolt up to a Bonez Super Flow Cat?

 

I think the aftermarket exhaust systems come with a pre-silencer between the downpipe (assuming turbo car) and catback. You'd replace the pre-silencer with a catalytic converter, and have an exhaust shop weld you the appropiate adapters/connectors to bolt it up.

Note I'm assuming the Bonez cat can handle the rotary engine's heat output.

 

When you say superflow, Im assuming you mean the whole superflow system? If so, no, no header will bolt up to that, since it is meant to work with the stock manifold.

 

^ Since there were headers and shorty headers for V8's, I was hoping that some company would have a rotary version of "shorty headers" that would bolt up to the super flow system....but I guess there isn't

 

Im not sure if youve ever seen our stock manifold..but as far as performance oriented it is not, to say the least. It turns 90* almost immediately after the exhaust ports. The only purpose it serves is for noise reduction, which it does well. It would be impossible to make a header within the size constraints of the stock manifold.

 

Sure you could, though it probably won't offer the type of signifigant gains you see with a longer header.


Rotary exhaust pulses are different beasts, and I'm still having trouble finding information on how to calculate the timing on them (as you would tune a piston engine's header for a given RPM range)

However, you wont find something that will bolt to the cat, you WILL be able to fabricate an extention for the cat to bolt up to a given header. Others have done this with the racing beat header and a 'stock fit' Y pipe. (around one and a half inches need to be added)
