MagnaFlow HM Grade Federal / EPA Compliant 通用型觸媒轉換器 99554HM

Bolt pattern lined up perfectly on my old Chevy, and the stainless steel shell feels solid. Check engine light stayed off after install, which was my main worry.

Bolted this onto my truck after the old cat gave up, and the check engine light stayed off through the first full tank. The universal fit gave me just enough play to line up the hangers without fighting it. Solid weld quality on the shell too, feels like it'll outlast the rest of the exhaust.

Welding this universal fit into place took some careful measuring, but once it was in, the check engine light stayed off through a full tank of gas. The stainless steel body looks like it'll outlast the truck.
