I'm Ready to Rock
I, like Cannonballer, purchased this exhaust just a week or two after it first came out. It was not available yet through American Muscle, or I would've purchased it here. I was fortunate enough to hear this exhaust in person on RTR #4 here in Charleston, SC. I was trying to decide between an MBRP exhaust and Borla, but as soon as I heard that RTR crank, i was done shopping.
Incredible sound at crank. Deep, loud, rumble. Cold crank gives you 15 to 20 seconds of 8/10 loud, then it quiets down to nice mellow rumble. Hit the gas and it wakes up and sounds like a v8 should. What I love about this exhaust is that there is no rasp and no pop. The new 5.0, and 3.7 for that matter, are so poppy, and I hate that. This RTR eliminates that pop, even during deceleration (which by the way sounds absolutely wicked). When I think v8 sound, I think RTR up to roughly 2500 rpms. In fact, when I first cranked it at work, my workmate (a Corvette owner) said its perfect, nice low rumble, mellow, no pop. "Absolutely perfect" he said. But i say, not so fast...
Now, i gave it 4stars because I want that sweet sound I hear below 2500 rpms to be there up top too. Unfortunately, its not. The exhaust quiets down dramatically while accelerating, the exact opposite of what I was hoping for. At Mustang Week 2012 Vaughn Gittin Jr. described it as a "robotic sound". Ummm, ok...if you say so. But more than anything it just gets quiet and that's a shame.
Now, Vaughn Gittin Jr. also claimed that this exhaust netted a 9hp gain. Is it true? I have no idea, there is no way that I would feel 9hp. But what I did feel was smoother acceleration. All through the RPM range, the 5.0 pulls with no lag and throttle response is excellent. That's a testament to the car itself, but I do feel like this was increased by the exhaust.
All in all, I really like it, but don't quite love it. If it kept its volume through the rpm range, it would be a perfect 5 stars.
