I thought I would write a bit about an exhaust system I dont hear talked about often. I put an AMH full system on my 2015 mustang
when it had 23 miles on it, I now have about 500. The stock exhaust is heavy, restrictive, and too quiet in my opinion. The Full system includes headers (I opted for high flow cats) an x-pipe, and a cat-back system. The parts are absolutely stunning, the build quality is highly evident. The install took about a day and can be a little tricky but if you have done headers before than it should be very simple. The sound is over the top, the startup might be a too loud depending on your tastes but the idle is the perfect volume and sound. Under the acceleration the exhaust is pretty loud but sounds fantastic, it rumbles with the perfect amount of sporty rasp to it. Not the deepest exhaust sound I have ever heard but not the raspiest either, I think it is a good balance between the two. There isn’t a drone at 1750 to 2000 rpm, but anything above that there is a bit. It still sounds good but you can hear it cruising in the car. The power difference is very noticeable, to the point where it’s testing the stock suspension under hard acceleration, upgrades to come soon for that. The high-flow cats do not filter the exhaust enough for the stock sensors, they will go off if you don’t have a tune that turns them off. If you have a tuner you can always just leave the sensors turned off and clear the engine code whenever it pops up. My only other observation/ complaint is people get confused about the name of the company being American Racing Headers and ask me who makes the rest of the exhaust, the answer is still American Racing Headers. If you want to stand out with an exhaust note that sounds great and is louder but not obnoxious this is the exhaust for you.
