My friend Adam recommended me to give Chris a call when I was looking for recommendations for installing a set of Kooks long tube headers on my Silverado. From the first phone call, Chris was very professional, answered all questions and is extremely knowledgable. Great communication along the way up until the install, to the point he cared so much about returning my phone call, when my number was misplaced he went through his caller ID until he found it. If you can remember when customer service was important, this is the place to get your car worked on. Would highly recommend Shamrock Auto! Thank you Chris.
