HIGH-FLOW CATALYTIC CONVERTER

IE’s performance downpipe includes a high-flow 200 cell per inch metal matrix catalyst located as close to the turbo as possible. Metal matrix catalysts are higher performance because the matrix web is thinner, allowing higher flow in the same size. Our catalyst is also a very large diameter, allowing a large flow area and maximum power. By being placed close to the turbo, emissions and unwanted unpleasant smells are greatly reduced

DIRECT BOLT-ON DOWNPIPE WITH PERFECT FIT

The IE downpipe replaces the majority of the factory exhaust from the turbocharger all the way back to the factory exhaust just before the rear axles. The downpipe section includes a new mount bracket and utilizes the factory mount points along with a tough interlock core flex section, this allows engine and chassis movement without stressing or cracking your downpipe. Easily connect the downpipe and catted mid-pipe using the simple and strong v-band connection. Finally, the mid pipe mounts to the stock rear exhaust with the included 3" to 60mm slip-fit sleeve, or easily adapt it to your cat-back exhaust of choice. In-house digitally scanned and designed for an exact fit and includes all hardware to make the install easy and straightforward.

Nice support but...
Size: 42DDD, Color: Black
I ordered this for my cousin who finds it very difficult to find bras in her size. She told me she wished she could find a good support bra without the wire because she had deep red marks under her old bra so I did some research and found this bra. She came over and tried it on and my first impression was WOW the support is great but it was very difficult for her to fasten all the hooks in the front due to her long nails. After some time she managed to fasten all the hooks and I noticed I needed to adjust the straps for her and she said it felt a lot better. This wireless bra looks so different on a woman with large breasts than the models in the picture, my cousin's cleavage was very substantial, unlike the model in the pic so if you are heavy set with large breasts, just know you will still have ample cleavage showing. After she put her top back on I noticed just how smooth her back looked, there were no bulges showing and she told me she felt like her posture was better due to the support of this bra. I have four stars due to the hooks being difficult to fasten.

You get what you pay for
Size: 54C, Color: Black
It's really nice n a great bra until u realize that the straps also have hooks, n the hooks keep coming undone n your boobs hanging out. Beware ladies you have to be big n also tall to wear this if not prepare n don't keep your important things in your bra bc if you're like me, u wanna keep the important things close to u. You will lose everything and not even realize it
