California Direct-Fit Catalytic Converter

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5551172. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. Designed to fit the 2009-2012 Mercedes-Benz GL450, 2009-2012 Mercedes-Benz GL550, and more, this direct-fit catalytic converter also interchanges with OE parts 164 490 51 36 and 164 490 52 36. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Squeaky bits broken 😞
Three out of five had broken squeaks. I have extra ones so I’m going to open them up and replace them but it’s extra work when the squeaky bits should be working.

Squeakers not squeaking
Cute but the problem is the bag was vacuum sealed and none of the squeakers work, even after letting them sit a few days out of package 😥

Disappointed
My multipoo loves his duckie, wrestles with it, sleeps with it, but today he found a weak spot on the back and ripped it, pulled some stuffing out. Have had it about 1 1/2 months. Disappointed! Stu he’d it up but not sure how long it will last🤨

Buyer beware this toy falls apart
I’m sorry to write this review, but I DO NOT recommend this item at all. It is as pictured. It is really cute. It is soft. My dog loves it. HOWEVER, the seams just fall apart. I have bought 3 of these since Christmas and it’s only the beginning of June so five months later and all three of them have fallen apart. Literally the wing will fall off, a foot will fall off and the seams keep coming undone. The stuffing is all over the house. This is one of the cutest stuffy’s. I’ve ever bought for my dog, but it is also the lowest quality and a complete waste of money. Highly recommend that you buy something else.
