Stainless steel exhaust systems for the M3
Hartge is a firm we visit regularly to sample their own individual brand of madness. Now it’s time to exhaust systems. Hartge has developed a stainless steel exhaust system for the new BMW M3 E92. There are two options available. These systems not only improve the looks but also the power and sound of the engine.
HARTGE stainless steel exhaust system with dual round tail pipes left and right, performance increase of 20 hp for M3 E92
HARTGE stainless steel rear silencer with dual round tail pipes left and right for M3 E92
“sigh” I love M3’s. One question though, how do you get those burnt tips on the exhaust? It look sort or purple and blue and is only on the tip? Or does that naturally happen over time?
