4 to 1 Exhaust

Anyone have recent install using a 4 to 1 exhaust system? Sky Dynamics or AWI. How was the install? Did components fit well or was modification necessary? If your project is flying; how do you like the system?

AWI

Everything fit nicely, no complaints. Not flying yet

I have a AWI 4 into 1 , fit perfect , 50 hours so far no problems .
