Korman Competition Exhaust Systems

These systems are the direct results of more than 35 engine dyno tests comparing different pipe sizes, configurations, mufflers, power results, and dB sound level measurements. Each system produces max power for each application. All are custom fabricated on a special jig, tig welded and finished in high temp silver paint. Factory mounting points are utilized.

IMSA Specification Competition Exhaust- Dual pipes transition into a single 3" oval pipe for best flow and maximum ground clearance, then into a tuned racing muffler with a single 3" outlet tip. As much power as straight pipes, but meets 108dB requirements. Bolts to stock exhaust manifold. P/N 1850287KM3R

Tracksport M3 Exhaust- Similar to above but adds a second muffler in the front section to reduce noise levels below 105dB. P/N 1850287KM3

Note: The above systems are not street legal since the catalytic converter is omitted

Clubsport M3 Exhaust- The most performance you can obtain from a street legal system. Similar to our full race system with 3" oval pipe and racing rear muffler. Also includes a high flow EPA certified catalytic converter. P/N 1850287KM3K

Ceramic Thermal Barrier Coating

We tested several header designs in our early R & D of the E30 M3, but found none that produced a noticeable advantage over the stock exhaust manifold. For performance, corrosion protection and appearance, we do recommend applying ceramic thermal barrier coating to the stock manifold. The ceramic coating provides superior corrosion protection, stain resistance, increased gas velocity and combustion chamber stabilization. Even if scratched or chipped its unique self-sacrificial properties won't allow oxides to form under the coating. Unlike other coatings, both the inside and outside of the exhaust manifold is coated. Expect underhood temperatures to be reduced by 20 or 30%.
