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.

Works great! Amazing actually!
Size: 4 Count (Pack of 1)
This works really well! I used it several times and really saw a difference. Unfortunately I had a root canal done and the following day I decided to whiten and I thought I was going to die! I didn’t know my front tooth was going to be that sensitive from the tooth canal. That was my fault and only telling this story as a warning! Do not use this after dental work unless your dentist says ok! Otherwise it works amazingly!

No sensitivity issues and works!
Size: 4 Count (Pack of 2)
I have what I would consider sensitive teeth and this doesn’t bother them one bit. I have used nightly for about 5 nights and can see a difference in color but again, no pain or sensitivity problems! I would recommend to anyone who asks what product to get for whitening teeth.

Impressive work...
I've used those whitening kit and it's my first time with something like this. I've done the charcoal toothpaste and working toothpaste and they made small changes to my teeth over a long period of time, but the whitening kit was a bit different. I applied the gel on my teeth and used the LED mouthpiece. There was a small change and a bit of sensitivity in my teeth so I waited a few days for the pain to reduce. I didn't realize that the sensitivity feel for for that very purpose. After a few days I applied another coating and used the sensitivity gel. The results were significant my teeth were two chart shades different. I was very impressed. I would recommend this for whitening your teeth, but if you feel a bit of sensitivity after use, use the sensitivity gel and red light setting on the mouthpiece. It really does help.
