I've recently had a milltek flexi pipe fitted to my fiesta st150 but after a few days it really started to sound horrible and now when I open the bonnet it really smells of exhaust fumes
My car has 82000 miles.
My car has a manual transmission.
The flex pipe may not be properly sealed, especially if you are hearing noise and smelling the exhaust fumes. Return to the facility that replaced the pipe to see if there is anything they can do to correct the situation. An exhaust leak is an unsafe situation for the driver and passengers.
