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.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.
