I have a question for those of you who have the newest Vetterman muffler exhaust (RV-7A, horizontal induction, IO-360), or those of you with exhaust expertise.
After talking with Larry and letting him know I am from Minnesota, he suggested that I have 2 mufflers. I recently installed the exhaust system (went on very nicely) and my question concerns the output of the mufflers. As I see it, I have 3 options:
1. Route the output of the first muffler to the input of the second, then the out put of the second to the heat box on the firewall.
2. Route the outuput of both mufflers to a "Y", essentially combining their output, then route the remaining leg of the "Y" to the heat box on the firewall.
3. Install a 2nd heat box (and control) and route the output of each muffler to its own dedicated heat box.
Is there a correct answer? A wrong answer? Benefits/disadvantages to each?
