i am planning for a future ECU upgrade and also putting in a NOS next year ....
I have already upgraded my w124's air intake into a drop in K&N filter.. and now its time to improve the exhaust system....
i guess the most economic method is to change its mufflers into a w210 model, anyone knows whether the implications would be a positive one?
w124 model : 4-2-1
w210 model : 4-2-2
will update with pics later.. cheers!
