One set of stainless Magnaflow 14815s (3" tips) (with mounts) already set up for direct install into your M5. One month old and about 1k miles. Mounted high and tight, perfectly centered in the valence opening. Three mounting points in the factory locations, rock solid and done by one of the better shops in Austin (over $300.00 for the installation). Just cut and go as it includes the head pipes that tie in to your stock exhaust near the rear axle.
The 14815 stock 2.5" inlets were removed and correct 2.75" size pipes were welded to the enlarged inlet area.
Excellent condition, as they are near new, never been in rain, etc.
They've just broken in and sound great. If you are local, you are welcome to drive and listen.
Let me know if you have Qs.
