Try to keep this from getting TLDR. I guess the short story is this place did great work…read more I bought a used car years ago, it had a "performance" muffler on it. After putting up with the loud exhaust for a couple years, I was done. I went to a place that was closer to me at the time, and they put a stock muffler on it. Still had a little rumble, but told not much to do about it. Job well done, or so I thought. Few years later, I start noticing a rattle on startup. It's not bad, it goes away after warm up. I carry on. Few months ago, it gets worse, still goes away, but I think I might have a transmission issue. Friend of mine I'm telling about it said he had the same thing once and he had a broken bracket on his exhaust system. I get under and see this mess. Cracked welds, pipe separated from the muffler. Also, they didn't install a mounting support above the pipe, probably one of the reasons it broke. Well, not going back to that place. I did a little research, and Big Johns looked like the best place. Little out of my way, but I wanted to make sure this time things went better. I believe John was there when I arrived, and had another guy who worked with him. I mentioned the whole problem, plus said it was still a little loud. He suggested a slightly bigger muffler, plus he installed a bracket support where the other place hadn't, and also redid the other two supports that were in place. The new supports were obviously more heavy duty. It did the trick. Also, I noticed my car was running better and a couple of issues had gone away. Car is now running like it did before all this started, and it's the quietest it's ever been. Charged me $200 and it was well worth it. At this point, I'm pretty happy. Be aware that when I was there, they only work on one car at a time. I don't know if he utilizes the other garage bay, but they work fast. It took maybe 30 minutes or so to do the job.

A few years ago I had an Chevy HHR that needed a new muffler. The dealership said it was all in one…read morepiece which was upwards of $800. I went to John and he cut and welded in a new piece. $220 out the door. His work is amazing and fair price. Now I want to upgrade my muffler on a 6.2L GMC Denali and this is the only place I will go.
