It's easy and cheap enough to replace the stock resonator if you don't like it. The only "issue" I have with the X-pipe and Roush setup is the cold starts can be loud, but to solve this I throw it in gear right away and it knocks down the sound by 50%. Other than that it sounds awesome. I remember when I first picked up my GT from the dealer, everyone was asking me to rev it when I got home, the stock exhaust was so terrible, I could see the disappointment in peoples faces after I reved it. Now when I rev my car windows shake.Reading these threads, it's amazing how different everyone's opinions are.
For the Roush AB with X/H-Pipe combo, I've read everything from "it's only loud when I stomp on it" to "it drones and is obnoxiously loud" LOL.
It's really hard to figure it out without hearing the combination in person on the same kind of car as yours (ie if your car is an AUTO, you need to hear the exhaust on another AUTO car).
I've had the Roush AB for about 4 1/2 months now and I've also had the Mishimoto H-Pipe sitting in a box for nearly that long; well, I'm finally going to have the H-Pipe installed tomorrow! If it's too loud, I can always have them weld the resonator back in place.
I will say that the Roush on its own with the stock resonator sounds awesome and mean at lower RPMs, and just "good" at higher RPMs, so it remains to be seen how the H-Pipe will affect the sound beyond the obvious "it's louder, bro!"

Haha, I thought the same thing. It's LOUD, but at the same time I could never go back to just the Roush axle-back and stock resonator. It's LOUD in a good way. I have a Premium auto as well, and like you I use the selectable modes to "tune" my exhaust lol When I'm out on the road I run Sport + or Track and let it open up, and when I get closer to home I flip it to normal or rain/snow and it shifts at lower RPM's and keeps the sound down, the rain/snow mode really tames down the exhaust with the low RPM's.Welp, that escalated quickly. ROUSH AB + Mishimoto H-Pipe = angry beast! Lol
It's loud AF, but in the best way. I can't imagine going back to the ROUSH on its own; it's just too badass sounding. On my auto trans car, it's absolutely fine in a normal mode and absolutely crazy in Sport+, which holds the lower gears a lot longer. The main caveat is cold starts, which are completely ridiculous; if I'm ever using the car early in the morning, my neighbors will probably want me killed, but putting it in gear quickly cuts the noise dramatically. After a few minutes of running the car, the exhaust tone mellows a bit and settles into this throaty deep tone that I absolutely love. I have no idea if the exhaust will ever start to annoy me, but seeing as it's not my DD, I have a feeling it will be on my car for a looong time.
I can say with certainty that the resonator delete doubles the volume WOT, but at idle it's maybe 15-20% louder than the ROUSH AB on its own.
My muffler shop guy was really impressed with the Mishimoto part quality after initially giving me crap about installing Japanese parts on an American pony car.

Also, like TZA888 said, Mishimoto, despite its name, is an American company with American made parts, or so I believe.
I actually ordered this today. I think this is perfect and makes it a deeper sound.I think this is a good balance: :cheers:
You tell me. ;)
You can get the same effect at lower volume with the resonated X-pipe. The resonator really makes some strange tones at higher rpm.One additional quick note:
I now understand what some folks have referred to as a "metallic" sound with respect to the stock resonator. I didn't notice it much as an issue prior to getting rid of the resonator, but now that it's gone, the overall tone is much nicer, without that faint tinny/metallic rasp. So, another good reason to get rid of that thing whether you keep your stock mufflers or not.
Have RAB's plus Mishimoto H-Pipes on my UK GT.
Love em and she gets compliments wherever she goes, even from fellow stangers with louder numbers...
