Weston aka smoke em built these for me last year. I bought them for my second set for towing. I used them for a week. I no longer have a vp truck. I believe they r 7x10. Asking $400.
I had Weston rework my DDP 150's when I changed my headgasket, and I now get almost 2 mpg more and the truck pulls so much harder and smoother at idle, and less smoke even
