Anyone have billy boat fusion system? How loud is it? Thinking of switching out factory npp for this . thanks in advance.

buddy had it on his c6 zo6 with npp, swapped them out, my self, i thought it didn t make much difference, but he liked it.

i put B&B PRT on my c6 z51. had headers, loved it. no drone and not as bad as the bullets.

Thanks walleyejack, I thought about the prt system as well. My car is all stock,no headers. I like the option of switching on or off with the fusion but am concerned about drone.

I agree those PRT's you had sounded AWESOME!! They are loud, but GOOD loud. Can't speak for the fusion.

I have the original Bullets and Headers. They are loud, although I really don't think they are that loud, but maybe I have hearing damage, who knows? The bullets DO DRONE at certain RPM range, (basicially while lugging.) If anyone tells you they don't, it's not true.

BUT, if your car is manual, it's very easy to get out of the drone range, and with radio on and top off, it's honestly not bad at all. I've had mine for 9 years and its not a problem, just be aware of it if you decide on going with the bullets, they are much cheaper than the Fusions too.

I had them on my GS, small improvement over the factory NPP. If you can get a great deal on them then I would say go for it but I would never pay full price for them. Good luck.

Thanks for the replies Red devil,. Was your gs an auto or manual? Did they drone?

walleyejack

they don t drone.

The car was manual and had Kooks headers with high flow cats. They had a slight drone at certain rpm/gear but nothing that should deter someone from buying them and it certainly didn't bother me (just worth noting).

you get drone in the garage undercover ?
