Just got this reply to my inquiry regarding compatibility:
Good day, Paul Sullivan:
I'm sorry it took so long for me to respond to your inquiry.
The Genturi is a very good unit to use with our system. Since our exhaust is hot and piping the exhaust inside the walls to the roof is kinda risky, the Genturi is the safest answer to roof exhaust.
Vehicle Systems Inc. have had a Genturi exhaust pipe hooked up to our production test station with no ill effects to either product.
My answer about the Hydro-Hot warranty is it will not be affected if the Genturi and exhaust pipe is properly installed .
If you have any other questions, feel free to let me know!
As always, Thank You!
