Had them replace factory exhaust with a true dual with mufflers. Did not like how the new one sounded, which was on me. I was not able to describe the sound that I wanted. It was finished at closing time since I went in that afternoon. I called them the next day and they worked me in to try a couple different options to see what I liked. Ended up going with dual cat back with 3 inch tips. Sounds great now. Better than I had hoped. Welds they did look good also. Highly recommended. Will be going back to have my exhaust manifold leak fixed. They quoted me $400, and charged me $400. Called a few places in Kansas City and they wanted up to $600 for the same service. Very friendly service, very well priced, and I highly recommend them.

Was told 200-250, until it was done! Ended up costing 400! Thanks for cutting us short on bills and my kids Christmas. Scammer!

Not sure how much it would be. If your just replacing a muffler, then I would say around $100. If your replacing whole exhaust, then closer to $250 without anything fancy like dual exhaust or tips. I have checked a few places in KC and they are quite a bit higher than Knapps. Best thing you can do is stop by to have them take a look and give you a quote.
