The S58 3.0 liter twin-turbo inline-six continues to be used in the MH3 GTR. The output is increased to 641 horsepower (478 kilowatts) and 590 pound-feet of torque using Manhart’s MHtronik auxiliary control unit. This is a significant improvement over the factory-specified 503 horsepower (375 kW) and 479 lb-ft of torque (650 Nm).

Additionally, Manhart provides many exhaust enhancements. The typical configuration consists of four 3.9-inch (100-millimeter) diameter tips, four stainless steel pipes with valves to control sound, and stainless steel pipes. The outlets can alternatively be had with a ceramic or carbon coating.

The tuner offers a racing setup sans cats, sports downpipes with 300-cell catalytic converters, and an Otto particulate filter deletion with 200-cell catalytic converters. However, Manhart sells the components for export despite the fact that they lack TÜV approval for usage on German roads. .

The MH3 GTR should be able to handle the road slightly better than the already outstanding M3 Competition. The purchaser has a choice between a lowering kit with H&R springs and the Manhart Variant 4 Coilover configuration using KW components.

Manhart doesn’t change the brakes. However, the tuner is happy to make those modifications if the buyer of the MH3 GTR requests them.

The firm adds a few minor aesthetic changes to the M3 Competition. The hood, back deck, and trunk lid of the MH3 GTR are all lighter gray with a dark gray body. The body receives carbon components for the diffuser, side skirts, rear lip spoiler, and aero flicks at the front corners.

The car is supported by six-spoke wheels that are 9×20 inches in the front and 10.5×20 inches in the back. In these pictures, they have a satin black finish, but Manhart can produce them in any color the customer wishes.

Recaro Podium front seats with a complete carbon-fiber shell are the only interior upgrade. Under the headrest, there is an embossed Manhart logo.

Manhart’s announcement is mum on the cost of the MH3 GTR. For comparison, a 2023 M3 Competition costs $77,695 with rear-wheel drive and $81,795 with all-wheel drive (after the $995 destination fee).

While it outputs a hefty amount of power, the S55 engine on the current generation BMW M3 simply doesn’t sound good. No matter what aftermarket exhaust you are using, the engine’s performance is ruined by the sound it produces. Luckily someone decided to do their best and create a good sounding, loud current gen BMW M3. The end result is surprising. Not only does the car sound better, it also seems to have a different personality.

With this particular current generation BMW M3 one element seems to make it distinguishable, the M3 Competition Package. Within the added goodies the most remarkable change is produced by the M Performance exhaust. While the sound of the engine may still make some BMW fans unhappy, for most it will definitely be an improvement. The added exhaust system is definitely louder. The car’s roar seems to give the car a whole new personality.

There are other advantages to installing an M Performance exhaust on your current gen BMW M3. One of the most important such advantages is the fact that installing such an upgrade does not void the car’s warranty. With this in mind, most fans will probably decide that upgrading their brand new current generation M3 is a must. Such a move is definitely worth it. There’s literally nothing to lose and quiet a lot to gain. The look of the M Performance exhaust system also contributes to the car’s new personality.

The current gen BMW M3 has definitely been improved with the addition of the Competition Package. Out of all the upgrades that form this particular package, the exhaust system by M Performance stands out. It makes the current gen M3 faster, louder and more aggressive looking. No matter how you look at it, this M3 variant is definitely an improvement over the original. This being said, the BMW fans, also, seem to be pleased with the far better sound the BMW M3’s engine produces at this point. M Performance parts in the form of the Competition Package are the key to this particular BMW’s brand new personality.
