I'm selling my lightly used Super Sprint sport muffler and x-pipe setup for the 2006-2008 Z4 M cars. Came off my 2007 M Roadster that I just sold but I believe it will fit a coupe as well (please verify prior to purchase).
The mufflers have 70mm tips and the fitment is fantastic. Sound is excellent. They definitely make you heard. Great pop and burble on throttle lift. If I didn't sell my car I wouldn't be selling the kit.

I paid $2,000. Used for about 9 months and 4,500 miles. No dents, dings or cracks. Asking $1,400 and am in Washington State. Shipping is about $100 for the complete setup depending on your location. PM or email me (firstname.lastname@example.org). Thanks!
