Active Autowerke BMW S58 G80 M3 G82 M4 Downpipes w GESI CAT



Active Autowerke BMW M3/M4 S58 Catted Downpipes

Active Autowerke is proud to release the highly anticipated Signature Mid-Pipe with X-Pipe for the BMW G80 M3 and G82 M4. While these cars have received rave reviews for their performance, the sound is a muffled one leaving the driver to wonder if they are really driving a BMW M-car. In order to solve this, Active Autowerke has created a full exhaust system for the G80/G82 which comprises this mid-pipe, a rear axle-back valved exhaust and a set of GESI catted downpipes. Together, this remake of the stock exhaust results in a G80/G82 with an amazing sound. You will feel like you are driving a true M-car again.

BMW introduced a new valvetronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continues into the G-Chassis models - the evolution to the S58 engine continues with the twin turbo variant used in the M-series vehicles. The Active Autowerke S58 downpipes for the G80 M3 and G82 M4 helps unleash some of the potential that is restricted by the OEM downpipes.

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 S58 is a bit restrictive, which results in slower exhaust gases and slower turbo spool. As the first step of the Active Autowerke G80 M3/M4 collection, we are introducing our catted signature down pipe.

The Active Autowerke G80/G82 S58 Signature down pipe utilizes 3 inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. We've incorporated stainless flex joints and then down to 70mm to meet the OEM exhaust system. We never drop the diameter to smaller than the stock diameter of 70mm.

This variant includes a pair of 4.5" high flow GESI catalytic converters 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 or exceed the standards set by the EPA, not CARB.

Active Autowerke S58 Signature Downpipes Benefits

The speed of a turbo's impeller wheel is limited by exhaust back pressure. A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke's Signature downpipes, your S58 can rev quicker, and deliver more horsepower and torque.

Minimizing back pressure while retaining daily drive-ability was the goal of our S58 downpipes. Owners can now upgrade to a product that is affordable, reliable, and easy to install.

After months of research and development, our engineers settled on a 3 inch diameter pipe which utilizes the least number of bends possible. The large volume helps the turbo spool as quickly as possible by eliminating back pressure during spool up.

Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your S58!

Active Autowerke G80/G82 M3/M4 Signature mid-pipe with X-Pipe



Active Autowerke is proud to release the highly anticipated Signature Mid-Pipe with X-Pipe for the BMW G80 M3 and G82 M4. While these cars have received rave reviews for their performance, the sound is a muffled one leaving the driver to wonder if they are really driving a BMW M-car. In order to solve this, Active Autowerke has created a full exhaust system for the G80/G82 which comprises this mid-pipe, a rear axle-back valved exhaust and a set of GESI catted downpipes. Together, this remake of the stock exhaust results in a G80/G82 with an amazing sound. You will feel like you are driving a true M-car again.

This exhaust system was designed and engineered to work with most after-market exhaust systems/mufflers on the market today with only a single cut needed in the stock mid-pipe. It is a bolt-on that can be performed by most and the stock mid-pipe can also be reinstated if needed.

This system replaces the restrictive secondary cats with high-flow 100 cell flat cats (for spacing). There are plans for a future resonator upgrade for those who prefer a smoother sound to their exhaust systems.

Active Autowerke is able to improve on the factory mid-pipe by increasing the flow and removing the two sets of resonators. The X-Pipe design has a scavenging effect that yields modest horsepower gains.

The Active Autowerke X Pipe system is constructed of 100% 304 brushed stainless steel and has a industry standard warranty against rust.

This latest addition to the Signature line up is a must for the true Enthusiast looking for a better sounding car to match amazing performance.
Features:

Durable 100% 304 Stainless Steel
Only single cut needed with Factory Style Flanges and clamps
Install to all systems that use factory style fitting
One year warranty
Replaces (not removes) secondary cats for better flow and sound


Active Autowerke G80 M3 and G82 M4 Valved Rear Axle-back Exhaust



G80/G82 BMW M3/M4 Rear Exhaust

Active Autowerke is proud to release the highly anticipated Signature Mid-Pipe with X-Pipe for the BMW G80 M3 and G82 M4. While these cars have received rave reviews for their performance, the sound is a muffled one leaving the driver to wonder if they are really driving a BMW M-car. In order to solve this, Active Autowerke has created a full exhaust system for the G80/G82 which comprises this mid-pipe, a rear axle-back valved exhaust and a set of GESI catted downpipes. Together, this remake of the stock exhaust results in a G80/G82 with an amazing sound. You will feel like you are driving a true M-car again.

At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For almost 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by the introduction of G80/G82 BMW M3/M4 collection rear exhaust.

The Active Autowerke G80/G82 rear exhaust was carefully engineered to increase the sound level over the factory M3 and M4 exhaust, while also allowing for optimum flow and resonance by reusing the actuators from the BMW valves. Every effort was made in addressing the overly quiet sound of the stock OEM exhaust while designing an exhaust worthy for an "M" car. We believe our rear exhaust combined with our mid-pipe and catted downpipes offers the best combination of sound and performance versus any other system on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory!

PLEASE NOTE - we do offer a version of this rear exhaust for those who only wish to replace their stock rear section (so keeping stock midpipes) but there will be an additional subsequent charge if you later move to an Active or other midpipe as the connecting pipes will have to be replaced. Also you should note that the dramatic difference in sound will only come with replacing the midpipe - the rear offers an upgrade but is more subtle.

We'll have official sound clips once the product is readily available

I'll also be posting install videos + sound clips once we receive the items to our warehouse

Nice, I was shown a prototype with cats on they're MP. But I guess they went away with it for the final product.

Does that mid pipe come as one piece as in the picture?

it'll be cut to save on shipping costs.

Mike they maybe put them on the diet lol. Looks good for a catted MP.

Besides sound, I wonder how much HP it'll add…

I hope they have a better video than that. It sounds too raspy for my taste. I prefer a deeper tone. Maybe it's just the video quality, won't scratch it off my list yet.

Does this mean that the mid pipe and axle back are the same diameter as stock? Why not 3" or bigger? Seems a bit strange to buy an exhaust that's the same size as the stock one?

I thought the same as well

[MannyM5]

Is there a single design Midpipe in the works?
Surprised AA didn't go the single route with how successful it was on the F8X platform and how good the single valvetronic sounds.

As far as i know, that's the only mid-pipe in the works now.

They must have tested the previous midpipe designs and were not happy with the sound

More midpipe pictures

Here is a clip of the active autowerke exhaust. This was taken using a camera phone by one of Active's employees.

I personally really like it; it's just the right amount of aggressiveness for me, especially on a car making over 500 HP stock.

Please note this is the full exhaust, including AA catted downpipes. If it's too aggressive for you, you can keep the downpipe stock and only get the midpipe and axle-back. It will tone it down significantly

you can also keep the midpipe stock and only get the active axle back for an even quieter sound

[bm5bullit]

I think that that sound is perfect. Not too aggressive and raspy.

Agree!

I like a little rasp.

Do you like how the car sounds in the video or you'd prefer to catless downpipes for a louder tone and more rasp?
