Aftermarket Tech in Chicago
 

Hello all! I am interested in a few things for my for my X5 as well ('08 4.8) and have looked at GT haus in Bensenville, IL, a chicago burb. Has anybody dealt with them or have any references for any place that is reputable? I am looking at possibly a Dinan upgrade when available for the X drive version on my 7er, and a Meisterschaft exhaust for the X5. Possibly some other things down the road. Any help would be great. Thank you all!
