Default Supersprint Twin Pipe exhaust sect.2

It's been a while since I posted on the forum board.

Here at Supersprint in Italy we have been quite busy in building a few exhausts for the E46 M3, in the last months; our US customers may be well aware of this.

We confirm, after all these years Supersprint still loves the M3 and the Z4M; we really want to do our best efforts for this car.

Most M3 owners may think that we have exploited virtually all of the performance exhaust design options for the S54 engine, with our multiple header versions, intermediate sections and rear mufflers.

We always thought that there was no more room left for improvement to be made, by any given exhaust.

On the N/A, stock engine, that is true, as our step race headers and race system have long proven to make the most peak power and the strongest midrange torque.

All of the Supersprint exhaust parts have been designed, developed between 2001 and 2005.

In 2007 we designed the latest step headers (also suitable for for RHD-spec cars), which accept the SS std. sect. 1, as well as the stock, sect. 1 .

Since the performance results were excellent, we have been rewarded with a lot of success, and we have been manufacturing our exhausts, non-stop, to make the owners happy.

Each and every of these original Supersprint designs never needed improvements, upgrades or other revisions, and we feel that they still do not need any.

Yet there is one particular idea, some blueprints we left sitting in our R&D documentation bins since 2001, for a larger diameter -tubing system.

Although we could have done, we never really pursued it, because we knew that most of the S54 engines had been used in stock form, only with relatively light performance modifications (airbox, fuel mapping).

We learned it by testing many Euro M3 cars on our Maha dyno, measuring the exhaust gas backpressure under full load conditions, and found that our std. exhaust sect. 2 always provided for the ideal flow, as is.

Larger diameter tubing would yeld no additional gains, anywhere in the powerband.

Years later, it seems that an increasing number of M3s are being tweaked with more radical modifications, some of them with BMW Motorsport's own race parts.

Since we have built a few exhausts for these 380-400 Hp (crank hp) Factory race cars in the past (including several Z4 M as well), we do know that these engines benefit from an exhaust section 2 made with larger size tubing.

Now we have made the decision to offer our oversized sect. 2 exhaust, making it available to the public.

The twin pipe design uses an tubing diameter is 63.5mm o.d. (57mm stock), with a small-area H-crossover pipe; the increase in the overall cross-section is + 25%, this measurement has been done vs. the the factory exhaust, on which the tubing has several crushed sections with an area compromised to less than 57mm even.

The increase over the current std. Supersprint, single-pipe sect. 2 is slightly smaller, yet significant.

The inlet flanges match both of the current SS race and the SS std section 1.

The outlet flanges accept any of the SS rear mufflers, the Touring (Street), the Sport and the Race mufflers.

In spite of the modular design, and the compatibility with all of the SS parts options, we recommend to use this new sect. 2 in conjunction with our race step headers and our race sect.1.

And we repeat, this particular SS exhaust setup makes the best gains only when used on 380-400 + crank Hp engines.


Sorry for the long post, in case anyone has questions, please let me know.

Have a nice weekend.

What's the projected price on this? Any advantages to this over your previous resonated one pipe design?

Default Re: Supersprint Twin Pipe exhaust sect.2

why go with a H section and not a X section? an H section would be right at home in the early 2000s and late 1990s… but like you said… advances have been made since then so why not an X section?
