BMW E24 635 CSi (M30) Kat. 6/'87 -> '89 (USA Model)

aka: Performance sport exhaust for BMW E24 635 CSi

Supersprint is the true exhaust specialist for all of the BMW timeless classics.

The 1987-1989 E24 635CSi is the very last version of the entire E24 model line; a very valuable, rare car indeed.

After years of refinements done by BMW, it uses the later generation M30 engine, also found on the E34 and E32 newer models.

The Supersprint stainless headers + full system is all the 635CSi really needs, to reach absolute perfection.

Our exhausts  have always been very popular among the E24 community, worldwide, and a selling hit within our entire exhaust range for BMWs; the 1987-1989 635CSi is no exception.

The Supersprint long primary, tubular headers had been originally developed for Hartge, one of the most iconic German Tuners, in the early 80's.

It was the main component of there legendary performance kits for the M30 engine.

This is one of the very first Supersprint exhausts using the then new, Emitec high-flowing metallic catalytics.

Up to date, this headers + catalytic system is the best complement to engine modifications, such as high rev camshafts, higher compression pistons, race intake systems etc.

The dual pipe, oversize diameter resonator and rear muffler are also equally important for free-flowing; plus they ensure a majestic, drone-free sound, and an unlimited durability as well.

Supersprint means easy, bolt-on installation and a flawless fitment, as always.

 Our exhaust is still hand built, offered in its original design, manufactured at the Supersprint facility in Mantova, Italy; the same exact place where it first saw the light, almost 40 years ago.

This full system is certainly one of the most valuable, long term investments for the evergreen BMW 635Csi.
