Active Autowerke is proud to bring you our hand made Signature S63/N63 Downpipes for the twin-turbo V8 BMW X5M, X6M, 550i, 650i, X5, X6 models. Please note that G-body vehicles with the N63B engine will need a different version of the downpipe - if you are buying a downpipe that also fits the F body cars, it will not fit your vehicle - Active is always doing R&D to ensure that you get a product with the proper fit.

A turbo impeller wheel speed is mostly limited by the exhaust back pressure within the system. If one could eliminate some or most of this exhaust back pressure, the turbo will spool that much faster and effortlessly resulting in quicker engine revs and increased HP. The Active Autowerke Signature down pipes are designed with the intent to maximize power. These down pipes are created with the least amount of restrictions possible by utilizing a full 3" piping throughout with the least amount of bends possible. What you will experience is a faster, more responsive engine because the turbo impeller now has the ability to spool that much faster. The end result is more power. Made from 304 stainless steel the handmade construction process ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match.

This variant includes a pair of 4.5" ultra high flow GESI catalytic converter that will NOT produce a CEL!

The GESi G-Sport Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESi UHO-Series Catalytic Converters are EPA registered and compliant for 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 high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.

The GESi UHO-Series Catalytic Converters are rated for engines putting out between 500 and 850 horsepower while maintaining a high flow capacity. The reduced back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions. Say goodbye to Check Engine Lights and failed emissions tests!

Please Note: These catalytic converters are not legal for use on vehicles registered in the state of California as a result of California Vehicle Code Section 27156 and 38391.

NOTE: Federal law prohibits the tampering of an emissions control device. Mobile Source Enforcement Memorandum 1A, allows for aftermarket parts to be used in the repair or replacement of emissions control systems, provided the emissions aren't adversely affected. There is no mention or reference to cell density or converter volume dimension. The GESI catalytic converter will produce emissions that will meet the standards set by the EPA, not CARB.

Dogs love it
This our second one. The fogs destroyed the first one. Good toy and great for applying peanut butter in the grooves.

Great toy
Style: Turtle, Style: Turtle
I bought three of these turtle toys as Christmas gifts for various family member's dogs. Every single dog loves it! My dog has never been interested in any other treat toy I've given her. She's just not a foodie type dog. But, she's crazy about this one. She loves that it's floppy and the crinkly noise that it makes. The treats are surprisingly secure but she's happy to work at getting to them because the noise is rewarding during the process. While the edges of the treat pockets are starting to fray a bit, it doesn't affect the usability of the toy at all. I'm honestly shocked that my dog hasn't Shredded the entire toy with the amount of enthusiastic chewing she's given it. The only issue I have is that the opening to the shell is a bit small. It's kind of difficult to get the toy's long neck stuffed into the shell. But, I suppose if it was any bigger, it would be too easy for the dog to pull it out. So, overall, this dog toy is a huge winner!

Good for dogs who like to rip stuff up
Style: Alligator
Apparently it’s really good because my dogs already destroyed it. So I’ll take that as a success. It’s a good size for big dogs. Not the strongest, but I didn’t get it for that reason, I got it to be destroyed. Both my dogs were able to play tug of war with it.

A great enrichment toy to keep your dog occupied
Style: Fox
Do you have a small furry gremlin disguised as a dog in your life that needs entertaining while you work? Get yourself one of these! PROS - it keeps a smart dog occupied for anywhere between 10-20 minutes - if keeps a less than smart dog occupied a lot longer - you can fit quite a lot of treats of different sizes in there - you can throw it in the washing machine when it gets too dirty - also doubles as a tug of war toy CONS - it gets dirty fast - if you have a heavy chewer they'll rip it up and render it useless pretty quickly - it squeaks (good for dog not for human) This is one of my girls favourite toys, even now that she's a bit older and doesn't need constant stimulation she still enjoys running around with it and digging the treats out.
