    Quality product-flanges thicker and pipe diameter bigger than stock. Beautiful welds. But with larger pipe size required alittle grinding down weld bead by 2 bolts to sit flat when tightened.

    The uppipe overall seems good quality, have had it on my truck for a month with no problems. Only issues I had was the gaskets that came with them were very thin. They didn't like to seal and were leaking . So I had to take it off and put a set of mahle gaskets and fixed the issue.
