Decided to pull the trigger on the FAE setup with the deletion of the old Silent Ride muffler. Being local to the FAE folks (Larry/Christina), I had the ability to drive down to their modest little shop in Spicewood to pick it all up. They are truly good people, extremely friendly and helpful. I could have done the muffler delete using mandrel bends from another vendor, but I decided the cost savings wasn't that much and I like to support the small business folks. The install was very simple and straight forward, the removal of the old Silent Ride muffler was probably the biggest pain of the entire process. All parts married up perfectly and definitely created much more room for impeller replacements!
I opted for the one piece Y with blended welds and installed flappers. I waited to purchase around Black Friday and Christina knocked $125 off the order total. Hope this post helps anyone who's been thinking about the FAE.
