The S54 is known for many great aspects: exhaust sound isn't one of them.
We cheered for companies making louder exhausts without rasps.
The bar was low.
2001 was an era where Americans had catalytic converts and Europeans didn't.
As CSL airbox conversions, cams and tuning were unlocked, new levels of power were found within the S54.
The exhaust became a bottleneck. Times does its time: technology and expertise evolves.
In this Special Series, I document sourcing, fitting and experiencing the 63.5mm Supersprint complete exhaust system.

There are many configurations available for the E46 M3 for enthusiasts to mix and match to achieve their desired performance, sound, and weight targets.

As a rule of thumb, Supersprint does not include installation hardware.
You will need to source new gaskets and bolts if you wish to replace them.
The exceptions are on exhaust sections that are not using the OEM configuration such as the twin-tube section 2.
Supersprint has been leading E46 M3 exhaust development since the early 2000s and haven't stopepd since.
They were the first to develop and market the stepped header configuration.
It's a unique engineering innovation to enhance power gains across all RPM, with no sacrifice to low and mid range torque often associated with oversized headers.
