Like most V6 Mustang owners, I wanted a more aggressive tone than the stock mufflers provided. To be honest, I went with these because they were the cheapest option American Muscle offered. I wasn't too concerned with the type or volume of the sound because I just wanted the stock mufflers gone.
I had them professionally installed by a local muffler shop.
I noticed a difference in throttle response and acceleration immediately. These really open up the exhaust and remove that factory restriction. By far the best bang for the buck in terms of bolt-on performance. I had installed the Roush cold-air system and BBK throttle body about a week prior to the exhaust and it really rounds out the package nicely.
Okay, let's address the elephant in the room, exhaust note and volume. There's a reason for the title of this review, and it's because these mufflers are LOUD and RASPY. If what you're looking for is head-turning, ear-plugging, scare-the-poo-out-of-the-neighbors-yappy-little-puffball, then go no further. You've arrived, and everybody within a 3 mile radius will know. They give a trumpety tuner-like rasp on acceleration, and crackles, pops, and gurgles abound on decel. Lots of distortion, especially at full-throttle. These are mean, nasty sounding mufflers. Definitely an "Are you sure you want to mess with me?" type of vibe. And therein lies the rub. Because they sound so good on the street when coasting up to that stop light, and then when mashing the gas to the floor when you pull away, their highway manners are atrocious. Way, WAY too much drone, at least for me. At 75 MPH in 6th gear under partial throttle at 2000 RPM the drone is so acute that it actually makes my ears start to tingle. I've started to avoid spending any time at all on the highway simply because I can't handle the drone. It's nearly impossible to carry on any kind of meaningful conversation, and turning up the radio to drown it out only makes things that much worse.
I know what you're thinking, "Well, ya dope, what did you expect? It's a Mustang and you installed a performance exhaust!" To which I would answer, "Yes, I know. Clearly my priorities were a bit askew as I made this purchase."
Please know that I'm not, by any stretch of the imagination, trying to dissuade anyone from purchasing these mufflers. In a nutshell they are by far, as mentioned above, the best bang for the buck when it comes to bolt-on performance. However, the price to be paid for that is what I consider to be (excessive) cabin drone at highway speeds. I am at present, unfortunately, looking for replacements; something with a nice balance of volume to tone that won't make me feel like I've run a marathon after a road trip.
