Catalytic Converter with Integrated Exhaust Manifold

California Manifold Catalytic Converter

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5551759. 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. This direct-fit catalytic converter is designed specifically for the 2004-2006 BMW X3 and interchanges with OE parts 18 40 7 514 503 and 18 40 7 514 505, among others. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. 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.

Quite good for costume quality
Color: Gold, Size: Medium
For eighty bucks this definitely isn't bad. It arrived slightly out of shape but after a few days on a good hanger, it all fell into place. I had no issues with fit--the medium wears as expected (6', 38" chest). It's a fun jacket, it's not far off from the product photos, and it certainly makes an impression. While it doesn't feel 'premium' per se, it doesn't feel cheap either. The liner is solid enough that the sequins don't feel too scratchy or restrictive. Definitely a niche item--certainly more of a costume piece than something you'd wear to make a bold impression at a formal event, and while not inexpensive, it delivers for the price and I don't think you could do much better for $80.

Fits like we had hoped. We purchased another one different brand and it was terrible quality. But this jacket was my son’s style and comfortable. Just what he was looking for

Shiny Small Sequin Blazer
Size: Small, Color: Black
This tuxedo blazer is one for the looks. It’s shiny black 100% polyester material, with a mesh net on the left side that has dark gold plastic sequins sewn on in a tree pattern. The material is taut with seams at the sides and the middle of the back. There is a single button. There are no pockets outside nor inside the jacket. The quality will hold up and is a decent value for the money. This was for a 5’5 male of slim build and fit quite snug. The measurement in inches: 17 - shoulders; 23 - sleeves; 27-1/2 nape to bottom of blazer.

Size a tad small
Size: Large, Color: Black
So many compliments so don’t buy this if you don’t like people to notice. I’d say fits a tad on the small side.
