Supersprint Front Exhaust for E89 BMW Z4 with 200 CPSI Sport Cats

Supersprint’s Front Exhaust for E89 BMW Z4 replaces both factory front pipes on the N54 and carries a matched pair of 200 CPSI metallic substrate converters from HJS, the German motorsport catalyst house Supersprint has sourced from for decades. A metallic substrate is thin steel foil rather than a ceramic monolith, so the wall between channels is thinner and more of the frontal area is open bore. Pipework is AISI 304 stainless at a nominal 1.5mm wall, mandrel bent so the diameter holds through every radius, and the threaded bung for the oxygen sensor arrives already welded in. This is the section to change once the rest of the system is open and the front of the car has become the restriction. On an otherwise factory 35i it is more converter than the engine will ask for.

Construction

Supersprint builds the Front Exhaust for E89 BMW Z4 at its own plant in Mantova, and the joins show it. Flanges are CNC machined stainless 7mm to 12mm thick, heavy enough to stay flat against a hot turbo outlet through repeated heat cycles rather than dishing and weeping at the gasket. Right and left halves are supplied together as one matched pair.

Applications

BMW Z4: E89 | 2009-2016 | N54 3.0L Bi-Turbo (306 hp, 35i)

Notes

This is the front section only. Supersprint specifies connecting pipe kit 982033 to fit it, and that part is not currently listed on Bulletproof Automotive; contact us to have it sourced with your order.
The Front Exhaust for E89 BMW Z4 is supplied as a right and left pair, so one purchase covers both sides
Supersprint builds this section to order, so it ships on backorder rather than from shelf stock
Designed to run with the factory emissions hardware retained downstream
The rest of the Supersprint E89 Z4 range is listed separately: Downpipe Kit for the 35is (708511), X-Pipe Centre Pipes Kit (982013), Rear Exhaust Right oO80 (982006), Rear Exhaust Left oO80 (982036)

Frequently Asked Questions

Does this front exhaust include everything needed to fit it? No. The Front Exhaust for E89 BMW Z4 covers the right and left front pipes and the two converters only. Supersprint specifies connecting pipe kit 982033 as a required companion and that part is not yet listed on Bulletproof Automotive. Contact us and we will source it alongside your order so the section goes together in one visit.
What is the Front Exhaust for E89 BMW Z4 made from? Supersprint builds it from AISI 304 stainless steel at a nominal 1.5mm wall, mandrel bent so the internal diameter stays constant through each radius. Flanges are CNC machined stainless between 7mm and 12mm thick and every pipe joint is TIG or MIG welded. The converters use a metallic foil substrate supplied by HJS.
What does 200 CPSI mean on these converters? CPSI is cells per square inch, the channel density of the converter substrate. At 200 CPSI the metallic foil core carries fewer and larger channels than a high density unit, so the exhaust stream meets less resistance crossing it. Supersprint sources the cores from HJS, a German manufacturer of motorsport converter hardware.
Will it fit both the 35i and the 35is? Yes. Supersprint registers this section against the E89 Z4 35i with the 306 hp N54, the 2010 35is Mille Miglia, and the 35is at 340 hp through 2016. All three share the same N54 bi-turbo installation, so one part covers the range. Check the Applications list above against your build year.
Is it in stock or built to order? Supersprint lists this section as available on demand, which means it is built to order in Mantova rather than drawn from shelf stock. Bulletproof Automotive lists it on backorder for that reason and will confirm the current lead time with Supersprint when your order is placed.

About Supersprint

Supersprint has built exhaust systems in Mantova, Italy since 1955, designing and manufacturing in house rather than assembling bought-in parts. Piping is AISI 304 stainless at a nominal 1.5mm wall, mandrel bent and TIG or MIG welded to CNC machined stainless flanges 7mm to 12mm thick; AISI 310S and Inconel come out where thermal load is highest, and catalyst hardware comes from HJS. Every application is developed against a baseline measured on the AWD MAHA dynamometer in Mantova, which is why the catalogue is model specific rather than universal.
