Eisenmann Sport Exhaust with Quad 83mm Tips - E63/E64 645Ci
German-made 645ci performance exhaust with 83mm tips
Eisenmann Sport exhaust for E63/E64 645Ci is the true German-made performance exhaust. Constructed from T304/T306 stainless steel and manufactured to strict tolerances for excellent fit, Eisenmann is famous around the world for high quality performance and sound.
The E63 Eisenmann muffler is a true polished stainless cat-back system that clamps to your stock center section. The system uses all of the factory hangers and gaskets and the fitment and alignment of the tips is one of the best we've seen. The tips are 83mm round straight-cut stainless steel - larger than stock and will require enlarging the opening in the rear valence.
Eisenmann's focus is on producing just the right amount of growl from the exhaust without being overpowering. It's a muted rumble instead of a thunderous boom. Eisenmann wants you to hear their exhausts even from inside the car without drawing too much attention from outside the car. As an OE supplier to several German marques, Eisenmann knows how to produce a sound that complements the persona of the vehicle. And each Eisenmann muffler can be matched with a center pipe to further tune the sound - a free-flow resonator maintains civility or straight pipe for greater volume.
Eisenmann is based in Hemmingen, near Stuttgart, and manufacturers all of their exhaust components in-house. All Sport systems carry German TUV approval and Eisenmann is an OE supplier to Porsche and Mercedes AMG, which means the factory must meet ISO standards. With close relationships and respect among German manufacturers, Eisenmann is often first to market with performance exhaust systems and always produced with outstanding quality. A two year warranty is included.
This exhaust section is built to order and ships from Eisenmann's factory in Germany. Because of the COVID impact, delivery times have been as long as 10-12 weeks after ordering but could be shorter. For the latest ETA info please contact our sales team.
