New Exhaust Break-In
New Exhaust Break-In
i recently got a magnaflow exhaust on my c280 w203 and had resonator delete. ive seen numerous times the words " break in" in relation to the new exhaust. some have said break in occurs within first 200 miles or 2 months, etc. what does this "break-in" mean? can anyone clarify this for me? thanks a billion
