How do I make my 2013 SHO sound like this car?

I'd rather shoehorn in a Mustang engine & exhaust than try to make the SHO sound like that. Or you could try changing mufflers. Or you could combine downpipe upgrade with a nice X-Pipe. Have you looked on YT for the various mods people have done? Plenty of samples from shoman, bpd, etc.

You could also try having MRT build a custom exhaust for you, they work with a lot of Focus ST's, might be up for a SHO project.

Not bad...and im a tough critic since i think about 90% of the aftermarket exhaust for this cars sounds terrible

I like it! Can I ask if you have any drone or resonance inside the cabin at certain RPMs? How much do you have in to it from a $ perspective if you don't mind sharing?

Cost me $610 total. Some drone but usually only under load. I am only worried about drone between 60 - 80 mph which is not enough to be annoying. Take into consideration im not PP so my rpm is lower at those speeds than a PP. Only thing I am wondering is to put a 28 inch X magnaflow muffler in place of the resonator. It would probably be quieter than the current stock resonator or about the same if i swap downpipes. Just a thought.

polskifacet, Could you please post a video of it in car? I'm highly considering the Magnaflow catback system for out Flex, and would like to cut out the 3rd cat at the same time. However since it is the wifes daily driver it can't be to obnoxious, or any level of obnoxious actually. From outsaide the car, that sounds great and I can't wait to swap out the stock for the Magnaflow.

Well if you want 0 drone, don't change the mufflers. Its hard to gauge sound from inside the car from a video, it sounds meh under load and does drone quite a bit under load since it is essentially a straight pipe. If you feather the throttle it is pretty quiet. I would really try and meet up with someone that has an exhaust, otherwise I can only give you my opinion. I would say the noise level is very acceptable inside the car unless you go uphill. Highway speeds its also not bad, 60 is basically silent. 70 -85 ish some drone starts. After changing the stock resonator to a magnaflow resonated X, the sound/drone was acceptable to me. I also think I have longer mufflers in the rear than what magnaflow has in their catback but I am not sure.

I want to say shoman04
