A1 Express Muffler - Sacramento. In case you guys are worried about other people working on your cars this place is great. I generally do everything myself and hate other people touching my car unless necessary (welding, fabricating, tires.. etc). The owner was cool to let me hang out in the garage while he worked on my car. I was able to see everything that was happening. He did an excellent job on my exhaust and the welds looked great. Took the time and did a great job and didn't mind paying a bit more for the care. If you are lowered don't worry about it, the lift is great and should accommodate that without damaging your car. Just my feedback! A+ to them.
