DYNAMIC MUFFLER & BRAKE SHOP

I needed a wideband oxygen sensor bung installed on my downpipe.  I brought in the downpipe (already had it off the car), with the position marked for the bung.  I needed the bung installed precisely because there was a very constrained place for the sensor and its mounting angle when in the car.  The technician listened carefully to my constraints, and had me check the position a few times in the process of drilling the hole and welding to make sure it was what I needed.  He did great, was very professional, and I was pleasantly surprised at how low the cost to install it was.  It was just $20, which included a threaded bung with a shoulder (which helps position it properly).  Of course, bringing in the downpipe already removed from the car helps keep the cost low, but this was lower than I expected.  The weld was strong (based on tightening the sensor in place), and no leaks.
