Hello fellow M5Board members. Yes, it's another one of those exhaust threads. I am a very new member here as you can tell by my post count (under 10 posts), so I figured I would introduce myself with my very first mod to my 2006 M5.
I wanted an exhaust that sounded like most of the super expensive ones a lot of us on here have and can afford. I, however, cannot afford to drop thousands of dollars on metal piping and fiberglass. So, I set out to create my own for under $500. I believe I succeeded since it only cost a total of $387 including installation!!
Anyway, it consists of:
1. Removing the secondary cats and replacing them with 4" SS resonator pipes
2. Removing the factory resonator and installing a Magnaflow Tru X-Pipe
3. Removing all 4 mufflers and installing straight pipes with dual 3.5" tips
Everyone seemed concerned with raspy tones and cabin drone. I believe the way to remedy this is making sure you either retain the secondary cats, or in my case, swapping them for resonator pipes. Here are pics and videos for you to love or hate:
