Exhaust Rattle - BMW 3-Series (E90 E92) Forum

MRSSIIM3 · 03-30-2010, 12:42 PM

I just purchased a used Harmon-Motives Vishnu Exhaust system. When I am on the stock JB3 map, the exhaust system does not rattle but when I put on Map 3 or 5 or anything other than stock, the car rattles because of the exhaust at RPMs between 1500 - 2000. After that RPM range, the rattle goes away. Any thoughts?

Rattle is coming from inside the cabin area. The back center consol and ashtray area. To solve this stuff a small rag I side the cup holder and ashtray and close it shut. Your rattle should be gone. Many people have experienced this and the old rag in the compartments solved the issue
