In my opinion, and after having the GT500s on my car twice...the JBA are not as loud as the GT500s. They are, however, deeper and more authoritative.

Mike this sounds great! Cant you tell any SOTP gain with this free flowing 3inch axle back compared to the gt500's?
So how loud do you think a gt500/offroad Hpipe with NO cam tune will be? I don't want my car loud at all, just a nice rumble.
how was the craftsmanship on them when installed compared to others? i read that the JBA's fit like crap, i wanted to get a set until i read that, i had JBA on my GTO and it sounded perfect.
Definitely going to consider picking up a set. Worried they may be too quiet with the factory resonators in though. I'm currently setup with O/R X and Roushes.
Hard to say, beacuase I went GT500's w/ OR X, then Pypes w/ O/R X, then the Roush and now the JBA's...So I will have to try that app.So in your experience the JBA's are are Louder than the GT500's or quieter!?
I have GT500's w/ catted 3" H & No resonators.......and I want it a tad bit louder. But NOT ROUSH Loud!
I downloaded a Decibel app on my phone and gonna try it tonight to see what it is....all you guys should do the same thing so we can compare!
1. Hold it roughly 12" from exhaust tip
2. start the car and see what it initially rates.
3. reset the decibel meter and then rev the car to 3k RPM
4. reset the decibel meter adn rev to 6k RPM
5. MOST IMPORTANT: Report the results! LOL
I currently like the volume of my O/R X and Roush, I don't think it's as loud as many make it out to be but then again loud is relative. However, I have currently started doing more highway driving and with my 3.31s, at 60-65 in 6th I'm getting more droning than I'd prefer. I wish there was a valved exhaust setup out for these cars. Maybe I'll look into working on something.
Louder than the JBA, but not as deep.
They fit better than any aftermarket mufflers I have tried yet. This includes, Roush, Pypes, Dynomax and MAC. The fit is comparable to the GT500s. Also, they are smaller than the GT500s, have a semi-polish and can barely be seen when looking from behind the car.
Well, they will be much more quiet than Roush. The Roush are actually amplifiers, I don't think they quiet the exhaust at all.

I liked the OR X Roush setup very much. However, I am a night owl, and just feel bad for my neighbors when I do a cold starts at 11pm...lol
I don't have neighbors close enough, 5 acres of property surrounded by fields, so I'm not worried about offending anyone. I'm just a bit tired of the slight drone on the highway to and from work, but don't want the car to sound neutered like it did stock. Do you still have the factory resonators? Do you find this setup too quiet coming off of the Roushes?
I wish there was a valved exhaust setup out for these cars. Maybe I'll look into working on something.
Do you think the GT500's could be polished by hand or would I be better served to paint them black?
Has every exhaust combo you have tried always made the popping noise?
There is, the Dynomax VT system is available for these cars.
Mike
Not really what I was talking about, but thanks for the heads up. I was thinking more along the lines of an electronically actuated flapper. Like the Vettes, VWs, and others.
