BMW Exhaust Parts, Mufflers & Catalytic Converters for BMW 3 Series E30 (1984-1991)

These studs will save the day! Stripped or corroded exhaust manifold studs are a major pain to deal with. Rusted studs fuse themselves to the nuts and back out of the cylinder head. These are M6x35 stainless exhaust manifold studs with new copper nuts that will make your manifold install a breeze! These studs have an internal 3mm hex so no more "double-nutting" or stud installers are needed, so no more galling threads! These have been a best seller for us since the late 1990s!

Turner Motorsport Conforti Performance Chip and Supersprint exhaust - a match made in heaven! 

Why Supersprint?

Supersprint performance exhaust for the M42 E30 318is gives a nice throaty and ripping sound. The Supersprint muffler is much freer-flowing than the stock exhaust which frees up horsepower in addition to improving the sound. This is a true cat-back system that bolts on to the stock catalytic converter and uses all of the same factory gaskets and hangers.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly
