Dude, you have noisy tires. One hour and $90 later, my Aero Turbine 2525XL was installed. The installer, looking at the muffler, said "This thing's going to be loud." Eek.
Well, the first time he fired the VX up after the installation, I practically shat myself. And I was in the waiting room. With the work bay door closed. Oooh.
But I have to tell ya, pulling away, it was noisier than I was hoping, especially at lower revs, right around 2Krpm or a hair below. In other words, around town driving. Guys with stock stereos need not apply. Sean, send that sub enclosure quick!
I did get on it hard leaving the gym tonight to merge into traffic safely and at higher revs, it actually quieted down. I'm sure it killed my chances of improving my own single tank mileage record. Trying to beat 365. I didn't manage to get through a second tank before swapping it in but I'll keep good tabs on my mileage from here on out.
Overall, I'm a "hair" disappointed. If there's room, I may try to slide a small resonator in there to kill some of the drone at certain revs.
I have (or had) two other cars, a Mitsubishi Evo which I put a Fujitsubo RM01A exhaust (quietest made for that car) and an RX7 that'll shatter windows three miles away at wide open throttle and 8,000 rpm. I guess I'm getting old and want a quieter car these days.
But man, every time I start the VX up, my neck hairs stand on end. I even find myself shutting it off then starting her right back up. Just to hear the exhaust note.
