Does anyone used a Magnaflow XL muffler on a Ford Focus??
I'm looking for a way to reduce the noise from my Focus ZX4, it has a OBX header and full 2.5" exhaust with two magnaflows but it's very loud.
It has an 22x4" on the straight section and an 14x6" near rear suspension.
On the rear close rear bumper it has nothing, just a pipe.
I'm thinking about placing a Magnaflow 13236 on the rear, what do you think? I don't know if this kind of muffler works well on 4cil engines.
