Thanks for the info. I've got a stock elbow and I'll get the Puck from rjc if I need to. I just thought maybe someone had one laying around from when they changed they're downpipe..
Not sure on the size of the puck. I used it many years ago on one of my turbo cars. The elbow has been sandblasted and painted with eastwood hi temp coatings.
Hi, its in between 1 1/4 and 1 1/2. Closer to 1 1/2. I dont think you can go much bigger puck size than what i have or itll be sticking to the inside of the elbow.
