In 2012, Toyota approached BMW with a proposal for a joint development effort for a new sports car that would replace the venerable and beloved Supra MK4 which was retired from production in 2002. After several years of design, development, and testing, the Toyota Supra MKV was launched in 2019 to mixed reviews but everyone agreed that it was a balanced driver's car.

Toyota and BMW choose to use the B58 inline 6 cylinder engine, a Valvetronic, single turbo version of its direct-injection engine. The Active Autowerke Supra MKV catted downpipe helps unleash some of the potential that is restricted by the OEM downpipe.

The dyno chart shows an increase of 18 whp using the Active catted downpipe and signature exhaust with the stock tune (just FYI our stage 1 and stage 2 tunes are showing whp increases of 53 and 94 using the catted down pipe and signature exhaust).

Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the B58 is quite restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke Supra MKV Signature down pipe utilizes 4.5 diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. It then tapers down to 3.5" where we've incorporated a stainless flex joint and then down to 80mm to meet the OEM exhaust system. We never drop the diameter to smaller than the stock diameter of 80mm.

This variant includes a 4.5" 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 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 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.

Buyers beware, I have a jack russell, and I just got this item ten minutes ago, my dog ripped it up.It is not indestructible, it is a waste of money. My dog is very aggressive with his toys. So back to the drawing board...So I can't return this item because, it's ripped up and they're not gonna give me my money back... So do not buy this toy.

P.O.S.
Color: Grey, Color: Grey
Toy is not as advertised. It is NOT for aggressive chewers. It is NOT indestructible. It is NOT for medium to large dogs. I knew the moment I opened it that it would be demolished by my 24 pound Miniature Blue Heeler. And here we are 5 minutes after giving it to him, picking up pieces of cotton off of the floor. This should be marketed as a kids stuffed animal. In no way shape or form is this a chew toy unless you have an aging toothless two pound Chihuahua. It would have taken longer for my dog to chew up the $10 dollar bill I gave for this. 💩

Great for aggressive chewers
Color: Grey
Tuff toy, my yorkie has been trying to tare squeaker out for about 3 days, he works on the fur part but so far it stands up to his chewing, I have gone thru 3 other toys this week so glad thi one works! It lasted 8 days. They need to make whole toy out of material and put fur on top of the tuff material. Once he found out wetting the fur softens it he pulled the seam apart.

Does not stand up to aggressive chewers
Color: Grey
Supposed to be for heavy chewers. My dog destroyed this toy literally in less than 15 minutes. Tore the tail which I sewed back together and then she tore off the nose and pulled out stuffing. Don't know how they tested this. She is only 6 months old and it didn't stand up to her play. Do not recommend if you have an aggressive chewer.

Won't last a day
Color: Blue, Color: Blue
My 50 lb. Pitt bull destroyed this chew toy in 15 minutes. One week later. I'm changing my rating from a one to a five. My girl spent up until now ripping it apart and pulling the stuffing and squeaker out. She had so much fun that I bought her another one. When I took it out of the box for her, she was so happy, she immediately tried to tear it apart.
