For over 30 years, Active Autowerke has been the one to turn to for high quality BMW performance products.

This variant includes a pair of 4" ultra high flow GESI catalytic converters (Gen 2 Advanced) that will NOT produce a CEL!

The GESI G-Sport High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESI HO-Series Gen 2 Catalytic Converters are EPA registered and compliant in 49 states and fully OBD2 compliant, perfect for use on 1996 and newer vehicles. GESI proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most "Check Engine Lights". These ultra high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.

The reduced back-pressure from this ultra high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions.

Not for aggressive chewers
Size: 36 Inch
My GSD ate half of it within 20min before I caught her. I don’t think it was meant for aggressive chewers so I can’t fault the product for that. My dogs did have a few hours of fun with it playing tug and it held up well.

Emotional Support Lizard
Size: 15 Inch
This was my Goldendoodle puppy's first toy, and a year later, it's still his favorite. It was light enough for him to play with it at 9 pounds, but big enough that he still loves it at 40 pounds. He carries it around, slaps his brother with it, throws it and chases it, sleeps with it, etc. He enjoys his stuffies also, but he returns to this one repeatedly through the day, so I know he loves it. It's a bit discolored, but still fully intact. If you have a dog with a soft mouth who isn't prone to chewing, this toy is perfect. I've purchased extras to keep in the emergency supplies in both the house and the car.

Not for puppies or dogs who enjoy chewing toys.
Size: 25 Inch
NOT FOR PUPPIES OR CHEWERS! If you have a dog that is teething or enjoys chewing on toys for soothing this is not the toy to buy. My 4 month old ate the sneak head off and the inside plastic ball squeaker was exposed and fell out and my puppy swallowed it. I tried to take it away from him but it was too late .. he already swallowed it. This caused serious vomiting days later in my pup. I’m not likely to leave negative reviews unless I truly have a horrific experience and this toy provided just that. 0 stars.

Good for kittens & cats too!
Size: 15 Inch
Bought this for our new kitten, 5 months old, and didn't know if it was a good purchase or not. He loves it! He can chew on it, drag it around the house, interact with us too. And he hasn't lost or destroyed it. The only disappointment is the head squeaker stop working. The placard stated it would work even if bit. Not a big deal, though; kitten doesn't like the squeak. LOL
