I know this is not for the purists
Here's my fist low budget / in a hurry attempt at turn down tips.
I used 45 degree 1 1/2 in ID galvanized exhaust piping elbows, wedged inside the ID of the round pipe in the Borla muffler. Then I used exhaust patching sheet aluminum (malleable) and fabricated 5in wide by 12 in long pieces that wrap around the oval Borla tip and then around the 1 1/2 in elbow pipe. Then I used hose clamps to attach to both. As you tighten the pipe clamp, it draws in the sheet metal and does a good job at holding the pipe in place. It is not moving. I hope it works well enough for 96 dB. We shall see!
