Cateram, vipers and merc slr
Who said anything about having the exhaust exit on passenger side?
Caterham exhaust is the drivers side, Viper's for the uk market had rear exit exhaustslets be honest your not going to see an SLR parked in the street are you
Surely cutting a huge hole in the sill is comprising its structural integrity and asking for a MOT failure?
Im going to be cutting a hole in the sill and welding half a pipe in and smoothing it, then exhaust will exit out on drivers side and will only stick out about an inch or so, should look like this when done.
