Thanks! I am obsessed with caring for her! She's a 2001, got her two years ago with 24k miles.
She's got 66k on her now, and NOT my daily driver. That big UGLY 15 passenger van is my daily. Driving the van all week to DC and back makes one appreciate the M3! Fortunately I have some great roads here.
Hey Shimmy!
The ceramic coated headers offer better performance for two reasons, one under hood temps are lower, oils temps seem slighty lower, but the best thing is the scavenging effects of the headers with them ceramic coated. Haven't heard of any negative effects on the cats. I did get those cats from Ebay UK when I installed the headers. Which was a PIA!!!
The headers were coated inside and out.
One of my favorite mods on this car are the lightweight APEX ARC-8's which are 18.8 lbs, and strong! Mated with the new Michelin Pilot Super Sports... WHOA!! FUN!!!
