I'm putting Vetterman's dual muffler/cabin heat source "tail" pipes in my RV-9. It provides two cabin heat sources, one on each exit pipe.

Have you folks used two separate fresh air inlets ? Or did you use a single source and split it with a "T" or "Y" fitting ?

If you used two separate inlet sources, where did you locate them ? Is it OK to put both of them in the baffle behind right rearmost cylinder ?

Any help appreciated ...

I'm running dual muffs on my Rocket. I'm doing it to increase the heat in the cabin by connecting them in series to the heat valve. I'm not sure why you would want two connected individually, but I guess you could do that. I'm not sure what the benefit would be.

I hadnt thought of that - mainly because Mr Vetterman told me that both muffs must have airflow otherwise the underlying muffler would overheat - otherwise I would just ingore the second one all together - I dont need the extra heat.
