Aero Turbine vs PV2 - with pics, sound soon.

here is the installation of the PV2

I dunno man, theres something in that sound that I am not able to put my finger on. Almost like, the resonance is higher pitched/tingy and louder than what I get with the PV1 (only exp I have since I dont have or never heard the PV2). Doesn't sound as deep throated and sounds like its pushing higher db.

Maybe its the video though. Never trust what you cant see in person, heh.

And wow.... that thing is big! Its like a melon cannon. At least its undercarriage and not something that likes that poke its turtle head out of the rear.

PS- looks like a giant C02 cart from an air rifle.

I just picked up the 2525XL off of ebay for $144 shipped! I made an offer at $160 which was accepted, and I had a 10% off coupon through ebay. Score!

Very cool! I was able to get mine for $175 directly from them... no shipping required...

As for the size, it's only that big because it has an internal resonator. I'm quite confident everyone would/will love the sound in person...

Still need to fulfill some video requests...

I have mine in-hand and I tell ya, I thought it'd be bigger from looking at the images. The PV1 must be really small. The Aero probably has stainless packing to protect the fiberglass or ceramic packing (whatever Aero uses).

So how loud is this thing in-cabin? I have to tell ya, it looks like it'll be noisy. I just want to avoid the droning.

My in cab noise isn't anymore than my Tires, I think you'll be pleasantly surprised Only Droning you'll get is when you're next to another car with a louder exhaust and your two noises resonate... It's weird.

haha glad im not the only one who experienced that phenomenon

with the PV2 i get some droning around 1800 rpms when the engine is under load.. very subtle changes in throttle position cure it quickly.. at 60 its audible.. on the verge of annoying.. at 70 its not bad.. at 80 you can barely hear it over the wind noise/ AC.. if i have my music turned on i can only hear it under acceleration and very faintly at 60... of course i have 150SF of dynamat in my VX too

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.
