New Exhaust
 

I need to replace my RV4 exhaust and wondering if anybody has installed a vetterman crossover on an RV4, the exhaust that was on there was a 4 individual pipe style.

Answer is yes, I have a neighbor that just completed his 4 and his plane has an O-360, constant speed prop with the Vetterman crossover exhaust. I have not seen any issues with it and it sounds just great.
Highly recommend Vetterman systems.

Why?
 

Why replace, and why are you interested in the crossover? Just curious...I have the 4 pipe on my -4, and love it...best sound ever! Only drawback is smoke system set-up is a little different.

The old exhaust went with the engine I sold out of it. I need to replace with a new system. I have the old style cowling and wanted to know if there were any fitment issues.
