B@B Decibel Level?

[lbszr]

Does anybody know what decibels the b@b, with headers at 50 feet would be. It would be 3rd or 4th gear, all in.

The NCM track has 103 @ 50 feet. No refund either, if kicked out, with group I'm planning on going with.

Or any guesstimates?

Sounds like (no pun intended), if you want to be sure you are under the limit, you had better go buy a dB meter and test the car yourself before you go spend the money to enter.

I can tell you that, except for one of the old "Desert Development" exhaust systems from the early-90s, the B&B exhaust for ZR-1s is about the loudest there is.

Even then, unless you've also removed your cats, I'll hazard a guess that you'll be ok.

Lastly, one thing you can do if you're nervous is find out which side of the track NCMs dB meter is located, then buy two big 90° bends and replace the B&B tail pipes with them and point them the other way. That is, if the mic is on driver's right, turn your elbows to driver's left.

There are several free apps you can download on your phone to check the dB sound level. One client required 35dB at 20 feet for a working dredge and I was able to show him that our discussions during the meeting far exceeded that. Got the specs changed.

YEP what he said

35db is quieter than the sound made by closing the door!

Little worried now, it does sound really good echoing off the wall at the track. No cats and resonator replaced with Dynomax mufflers. Guess I'll take resonator, the elbows might be the way to go though. They give one chance to make it right. I'll check, maybe the oem can be put on, but maybe not feasible with headers hookup, especially at the track.

If the original did fit. Would that make it run richer, sense it's tuned with b@b?

The apps I found did not go higher than 70 or so. They said the cell phone mics where not designed to receive that high.
