I bought some VRSF CATLESS downpipes for my car. Had them in for about 100 or less it was just for the weekend. Car had issues and turned it back to stock for some warranty work.
Don't know if they fit the M6 but I heard they do.
Also have the NGK spark plugs needed for stage 2+
Also used for less then 100 miles.
No damage, legit brand new. I'm in SoCal can ship at your expense.
Have any questions message me.
These downpipes are a direct fitment and have zero issues rather then other brands not bolting on or leaving gaps etc.
Turbo spoon is amazing.
Plugs and spark plugs for $530 or downpipes for $480.
