Corsa Xtremes On A Daily Driver: A Review
Okay, so this is as honest a review as I can give. Like many of you probably did, I watched (literally) hours of YouTube footage when trying to decide on the best exhaust for my 2017 GT. The Xtremes immediately stuck out to me as sounding especially good, but I was also worried about the volume since my Mustang is my daily. Now that I have them, here are my thoughts.
Exhaust note: absolutely incredible. Seriously. The tone on these in person vs YouTube videos does not even remotely compare. In addition to the general sound (deep growl at low RPMs, screaming at high ones) there are so many subtle noises the videos don't capture. I've heard other reviewers describe it as the sound of exhaust gases racing through the double X and that's probably the most accurate way to put it. They crackle, pop, growl, and make an incredible variety of noises. The exhaust note is better than I could have ever hoped for.
I think one reason it's so good is because unlike other exhaust notes for the S550s, this system doesn't try to stay deep throughout the whole RPM band. The Coyote engine is no longer the deep, growling muscle car engine of the old 5.0s. It loves to open up and rev and this system complements that perfectly. Honestly, it reminds me of the old 4-valve 4.6s (a la the 03/04 Mach 1).
Volume: as others have said, the reason this system is so good is because it's loud when you want it to be and fairly reserved when you don't. Make no mistake: it's basically always louder than stock, but the stock exhaust is also *very* quiet. The cold starts *are* quite loud - if you live right next to someone, or maybe in an apartment right in front of someone's window, this may be an issue for you. If you have even a moderate amount of space between you and your neighbors, you'll be fine. Cruising through the neighborhood at 3AM? Just stay in lower RPMs and you're fine, you won't be waking anyone up.
However, when you're on it, it *does* absolutely scream. These are very loud *when you want them to be* I was very nervous that they would just be loud all the time, and while they are *audible* all the time, they aren't melting-your-face-off loud unless you're driving in a way that would reflect that. So, is this system too loud for you? That depends on where you live, how and where you're driving, etc. In general, my answer would be no. But if you live right on top of someone, it may be. Just depends on your situation. I've had no issues here.
Install: fairly straight-forward. Either get a lift or about three sets of hands or you'll probably be working longer than you think. Takes some effort to get everything lined up but overall it's nothing too terrible and can be done in a couple hours, maybe a little more.
Cost: well, these aren't cheap. What they are, however, is 100 worth the cost. The tone is intoxicating, the volume is insane when you want, docile when you don't, the build quality is fantastic, and most importantly: no drone. Like, none at all. Seriously. You get what you pay for. If you want something that doesn't sound awful on the highway and isn't constantly destroying your hearing, this is what you need. Corsa delivers, end of story.
Overall impressions: I am absolutely in love with this exhaust. Don't be scared of some of these reviews that say they're "INSANELY LOUD!!!" They *can* be, but they aren't all the time. This is the best exhaust I have ever heard on a 2015 Mustang, easily.
If you're on the fence about these and have the money and your living/driving situation allows for it, get them. Stop thinking about it. Just go for it, I promise you won't be disappointed.
