So I have a 2016 sxt charger. I already deleted the mid muffler and end resonators. I want to delete the cats and install an x pipe (I don't know why dodge didn't just do an x pipe to begin with, smh...). What price sounds reasonable for a muffler shop to do this? If it helps, I'm located around San Antonio, TX. Thanks!
Are you sure there is not already an X-pipe on the exhaust system? I don't have any specific info saying there is an x-pipe on the 2015+ models, but the 2011-2014 models had one, and I cannot see them removing that from the exhaust system design as a part of the 2015+ refresh...maybe they did, but it would seem counterproductive to do so,...
Anyway, if it has an x-pipe, it will be behind the cats and ahead of the mufflers, somewhere in the mid-forward section of the car, right before the tunnel in the underside begins at about mid car. Jack it up and crawl under there a little ways, you should be able to tell if its got an x-pipe once and for all. Dollars'll getcha donuts that it does have one already.
To your question about how much it will cost to have an exhaust shop remove your cats, I am going to say $0.00 most likely.
AFAIK, it would be illegal for them to remove the cats on a car driven daily on public roads (and thereby subject to state inspections every year) without replacing them with a new set of [functioning] cats. And not only would they be breaking the law, the laws they would be running afoul of are federal in nature. That means big fines and massive headaches for being found in violation of them.
: no one is going to even entertain the idea of removing the cats without a plan to replace them at the same time.
But even if you could have them removed, it wouldn't provide you much, if any, of a performance gain in the car's operation. Not to mention the PCM would notice them being gone, throw several DTCs, and illuminate the Check Engine Light until the missing data points were reinstated or turned off (not a simple task).
That is important to know because the PCM's operation of the engine will never enter closed loop mode as long as the CEL is on. Which means it'll constantly be using an air/fuel mixture where the proper ratio is merely guessed at (open loop mode) instead of calculated and recalculated on the fly a hundred times a second like it should be (closed loop mode).
: You will be down on performance across the board, down on MPGs in both city and hiway, and spewing more pollution in the surrounding environment than necessary if you have the cats removed.
Extra pollution (more than necessary) may not bother some folks, but if you live in a large city like I do, that buildup of VOCs and the resulting ozone on hot, muggy days can be seen and felt. And it ain't anything you will enjoy, I assure you. Not to mention the affects it has on your breathing if you have asthma or something similar...
