MagnaFlow 2004-2005 Buick Rendezvous 3.4L / 2004-2005 Pontiac Aztek 3.4L 加州等級 CARB 認證 直接安裝觸媒轉換器 4551038

The mandrel-bent tubing really made a difference in gas flow, and the CARB compliance gave me peace of mind for California smog checks. It bolted right up to my Rendezvous without any cutting or welding needed. So far the check engine light has stayed off, which is exactly what I needed.

My check engine light finally went off after I bolted this in, and the direct-fit design meant zero cutting or welding on my Aztek. The mandrel-bent tubing looks like it flows way better than that crushed stock pipe ever did.

Took about two hours to swap out the old one, and the mandrel-bent tubing lined up perfectly with the existing exhaust. The check engine light stayed off after a week of commuting, which is exactly what I needed for passing smog here.
