I just have a question... what exactly are "performance" shops, I mean, what sorts of mods can be done at these shops? Are we talking about strictly mods to enhance performance only? Would these performance shops be able to install aftermarket exhausts? Thanks.rickrick17 said:Hi everyone.
I need some reccomendations of good performance shops in the DC/MD/VA area.
I am getting my M3 in 3 months and I want to do pricing on my mods.
Thanks in advance!
