DON"T GO WITH MIDAS or one of those one size will make it fit all places.
The proper system means alot! The wrong amount of back preasure can cook your CAT or fry your O2 sensor.
Check out BMP first!
Is there any risk in putting an after market muffler in my 528e, in regard to length, diameter, the internals... so long as it fits. Or do I have to take all measurements and make sure they all match?
