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.

Great suit
Size: 12, Color: Mint Green, Size: 12, Color: Mint Green
Very nice suit. Love the material. My 11 year old is tall and slim- 5’3”, 80 lbs. I got a size 12 for the length. The jacket fit perfectly, the pants was good length and has elastic in the waist to adjust for size. Overall, it’s a good suit and I’d recommend it.

Nice Suit - Light Gray Color OF Suit IS Not A Solid Light Gray, It Has Linear Designs
Size: 12, Color: Light Grey, Size: 12, Color: Light Grey
I had purchased this polyester and linen blend suit for my son, in size 12Y for him in the color light gray. The color of the suit depicted in the advertisement arrived to be a bit different upon arrival. It's not a solid color light gray, it actually has small black liner lines dispersed all over the suit. The coat features a single button in the center, and there are two side pockets fairly decent sized. Unfortunately right above the pockets are red colored lineal horizontal lines. I don't think those lines are part of the coat's design, there definitely is some printing malfunction. It is hard to see in the pictures advertised, you can see it in the pictures and video I have posted clearly. The material of the suit is fairly acceptable, actually better than expected. The child can actually wear it multiple times for various occasions. The suit emits grace along with acceptable stitching in every apparel along with the bowtie. The suit did arrive in a slide bag all folded up, so there were a number of wrinkles especially on the coat, its as if it had lost its shape. I will definitely need to steam iron it before it will be worn. Just like the coat has pockets the tailored pants also have two side pockets, and belt loops in case need of belt if the pants are loose. I'm actually glad I had ordered two sizes up because compared to his current measurements the suit is big on, especially the pants waist and length. I had measured the suit myself and below are the measurements. Pants Waist - 15.25 Inches Pants Length - 35.75 Inches Pant's Inseam 25 Inches Coat's Length - 24.5 Inches Coat's Shoulders - About 14.5 Inches Coat's Sleeve Length - 22 Inches Coat's Chest - 15.5 Inches In addition to the suit, I also received a solid colored light gray, bowtie. The bowtie has an adjustable strap, so you can set the bowtie to your comfort in the collar. You can wear it along the suit or without it if needed to match with something and still manage to look a show topper!. The coat has nice shoulder padding therefore it sits across the shoulders nicely having it hold its shape and style. Overall it's not a bad purchase, suits like these always come in handy for a unexpected or expected events. I'm glad I had purchased this suit I'm sure it'll come to use one day.
