If it's not 4-2-1 I don't care. ;-) I won't add any parts to my F355 that will neuter the glorious F1 music.
Hmm, the U.S. importer and sponsor here offered them as a group by for $5,500. So, apparently you can get them less by bypassing the proper dealer. Hopefully you don't ever have a warranty issue...
You are funny Dave. Really... FYI. I have zero skin in this game. I have new OEM headers that are working just fine Just helping the community with correct information. Brexit is your friend and if you aren't aware of it then that is on you. As far as warranty is concerned I don't think that is an issue. In fact I know of a warranty issue that was resolved immediately with no problem. Oh and FYI. This has absolutely nothing to do with any group buying.
