|I wanted some protection for my catalytic converter, and Signal was available and had one of the best options available for a Honda Element. Avi gave me a quote that was agreeable, and required extra time due to rust issues. Work done on the engine was also something done that left my engine running like it was new again. I will be going back here when more work is done on my vehicles that I cannot handle. A pleasure doing business with locally owned business like this.
