I purchased the Holley Sniper, 550-552 from Summit Racing Equipment.

My no-brother-good in-law, who is an excellent fabricator made the adapter. He took a piece of 1 5/8” 4130 tubing and turned the ends down to 1 1/2” and then TIG welded 1 1/2” exhaust pipe flanges onto the turned down ends. I can get you the vendor and P/N of the exhaust flanges if your interested.

Thank you for the compliment.

Put a few more miles on the truck today. Starting and throttle response have made the project worthwhile for me.
