Overview:
Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 49143. 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 2008-2013 Infiniti G37, 2014-2015 Infiniti Q50, and more, this direct-fit catalytic converter also interchanges with OE parts B08B3-1ET0B, B08B3-4GB0B, among others. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Size down! But overall comfortable and cute and good quality
Size: Small, Color: Light Yellow
Overall it’s cute and comfortable, but my advice is to SIZE DOWN!!! I wish I would have, but I’ve already washed it so it’s too late. The straps are adjustable, but even so, I’ve had to tighten them as far as they’ll go. For reference, I am 5’1” and 125#, rectangle shaped/boxy body with a very small chest and I got a Small. The top gapes open on me and the dress is longer than I prefer for this style. Material/fabric is nice and good quality and it’s a perfect one-piece easy outfit for warm days. I like the yellow color too. It is tricky to find the right bra to wear with it, though. Got lots of compliments on it the first time I wore it.

Cute, Comfy & Flowy—Great for Plus Size!
Size: XX-Large, Color: Black
I really like this dress!
It’s super comfortable and lightweight, and the material feels soft without being too thin. It has a nice flow to it, so it doesn’t cling to your body, which I really appreciate.
For reference, I’m 5’4” with a 46” bust, and the dress fits well overall. The length is great, and I love that it has a relaxed fit—it’s easy to throw on and still look put together.
The pockets are also a nice bonus and actually usable.
The only thing to note is the top area can be a little more open on the sides, so I personally prefer wearing a sports bra or something cute underneath. It actually works really well styled that way and gives that “layered” look.
Overall, it’s a really easy, comfortable dress that you can dress up or down. I’ll definitely be wearing this a lot!

Great dress for running around town
Size: Large, Color: Coffee
I love this dress. I ordered this dress fist in a medium, then a large. I probably would have been fine in the large, but I just wanted a little more room and I wanted it to come to my knees so I ordered the XL and I love it. The material is a cotton knit type material similar to a t-shirt with a little stretch to it. I am 5'2", #170 and the XL gave me the fit I was looking for, being loose and comfortable. There is a second layer under the dress that has shorts and a tank top built in. Unfortunately, you must take the entire thing off to use the restroom but I am considering adding snaps to the crotch so that it is easier and I won't have to completely undress to use the restroom. The olive/army green is beautiful and I am planning to order the plum color dress as another addition to my summer wardrobe.

Cute Idea, But Fit Didn’t Work for Me
Size: Medium, Color: Coffee
The material was nice but also a little different than expected. It’s soft, just not quite the level of softness I was hoping for.
I do think it’s worth the price overall, but it’s not something I would personally wear 24/7.
I ended up returning it because the fit just wasn’t quite right for me. It was very loose up top but really tight around the bottom, which made the cut a little off for my body type.

Postpartum Certified!! :)
Size: Medium, Color: Black
I am currently a breast feeding mother who is only 5 weeks post partum. Heading into the summer I needed clothes that fit my changing body and gave me a little confidence that I’ve been lacking recently. This dress has completely done it!!
The material is extremely comfortable and not too tight on my body. It’s long enough to give me the coverage that I’m comfortable with but still makes me feel cute. Without knowing how to shop for or what size my body is at after birth, I listened to the comments and got a medium when I was thinking I might be a large and it fits great! Definitely size down though! I will be getting more!!!
