What Owners Say
Owners and enthusiasts report mixed experiences with AMS Downpipes, with several noting they're effective when properly manufactured. Some users praise the warranty coverage for US customers and recommend professional dealership installation for best results. The catted versions receive particular attention, with owners describing them as "amazing" despite occasional CEL issues that may resolve over time. However, concerns exist about quality control and tolerance consistency, with some suggesting these are knockoffs of tighter-tolerance designs. The general consensus leans cautiously positive—when you get a good set, they perform well, but potential buyers should be aware of fitment variability and the likelihood of check engine lights with full racing downpipes.
