The new generation of Supersprint rear mufflers, called F1 Race, bring the sound of the E92 M3 to another level.
The canister innards use a mix of resonating chamber and straight-thru design, which greatly enhances the sound note in the high rpm range, while leaving the inside-cabin noise within reasonable levels, at cruising speeds.
Of course, the increase in performance, when used in conjunction with the remaining, well proven Supersprint exhaust components, is guaranteed to be unparalled.
The goal of these new Supersprint exhaust mufflers is letting the V8 scream to be  heard from far away, yet maintain the dB output civil enough, to meet most of the Race Track noise regulations.

As in the previous "Racing" version:
-Pipe-diameter and piping remain 65mm
-OO80mm Endpipes, straight edge (not rolled ends, lipless) are the same

That means, the difference between the two versions is just the character and level of Sound:
Rear-silencers  "RACING": "classic Racing Sound
Rear-silencers "F1-RACE": Racing-Sound especially in the high rpm-range more "screamy" and louder
(similar like a Formular 1 car; therefore the name)

The rear section is the first step of the R&D and the whole exhaust system optimization process.

The sporty sound is achieved from the accurate selection of the piping sections, of the unique inner silencer design, and dedicated to the specific vehicle model.

The outlet style is determined with the same care and ensures a pleasant car design customization, enhancing those features that make it incomparable and second to none.

The installation procedure is easy and quick, because it exploits the same hangers of the stock exhaust. No modifications, neither to the chassis, nor to the mechanical parts, are needed.

Every single safety features required from the car manufacturers are fully respected. No exceptions.
 
An example is the ideal tubing layout and the perfect thermal isolation from the excessive temperatures in the critical positions of the mechanical parts.
In this case all the Supersprint exhaust components fulfill the strict JASO (Japanese car Industry) obligations in terms of fire dangers, in the event of an accident.
The material used, in this case AISI 304 hi-grade stainless steel, are exclusively genuine European products.
 
The tubing and the stainless foils thicknesses are accurately selected and are properly used to match every single Supersprint exhaust applications upon the desired features which have been decided during the R&D process.
 
The durability of the Supersprint exhausts is by far longer than any of the stock equipments and is fully guaranteed for a 36 month time, limit-free mileage
