Perfection Muffler Service & Auto Clinic

I have had two experiences with Perfection Muffler, one maddening and the other good. First of all, let me say that they're great guys! Just make sure of the work that you are having done beforehand. On the first visit, I took my vehicle into them to have a generic catalytic converter installed after having installed a factory-new downpipe and rear exhaust section myself (the factory converter, however, was exhorbitantly priced). I had assumed they would weld the existing converter flanges onto the new unit and bolt it in. Instead, I found out when I got home that they had cut the flanges off of the brand new pipes and welded in the converter, leaving me with a single-piece manifold to tailpipe exhaust system. Now, if something fails or develops a hole, I'll have to have something pieced in or replace everything. On the second, I took a hard-to-find catalytic converter into them to be installed to replace the failed factory unit. I was unable to get the bolts out and replace it myself. They offered me the option of cutting the bolts off and replacing at the flanges to retain the factory exhaust setup, or cutting the converter off of the existing flanges and likewise witht the replacement unit, and then welding the replacement converter to the existing flanges. I opted for the first solution, and am very pleased with their work. In both instances, the price was fair and the work was done quickly and when promised.
