i took my civic to a shop to have an estimate on putting a flowmaster muffler on it. stock weld on the in pipe rusted and broke, so needed a muffler. since it's a cut and weld application, one shop said about $87 for labor and the pipes they'll need to bend and weld. another shop said about $50 total. so you know where i'm going (especially since the cheaper shop came highly recommended). but the reason it's a cut and weld is because the muffler i got doesn't have the exhaust hangers on it, so they need to cut the stock ones and weld them onto the new muffler, and it's a 1 1/2" pipe on the stock exhaust, the flowmaster is 2" in and out, so they need to weld in the adaptor piece. i'm in PA, so the labor rate is cheap compared to what you pay out in NY.
