Issues after dp install! any advise?

bmw335icasa · 05-06-2011, 05:51 PM

Just installed a pair of macht schnell catless dps, first impression is they look good and sound good eventough the rattle is a bit anoying.
However i have experienced the following things:

Car vibrates and makes a weired noise when i turn left (i did check the steering wheel rack and did a realignment after install, i also checked the metal heat shield on the passenger side right above the rack as someone already mentioned in another thread)

The engine makes a constant whisteling noise a low rpm , i did check for leaks and found none

I'm a bit confused any feedback would be appreciated

Sorry to bring this back to life, but did you ever get this figured out?
