Loudest recommended exposure WITH hearing protection 140dB Jet engine at 100' 140dB. Level at which sustained exposure may result in hearing loss 90 - 95dB

Robert maybe your meter is off a little.

All of my meters are calibrated annually. I knew someone would doubt my number so I decided to get a DB reading while on a plane. As you can clearly see the DB meter on my phone is at 140DB, While this is a mere cheap app for my android Jim V. can verify that the reading is not that inaccurate as we tested this app next to his DB meter.

My B&B's were crazy loud.

My Corsa's even got special treatment by the SDSD.

Robert:

Very nice job. It sometimes hurts to see a very good car dismantled like that, but I know you'll get it back together as good as new. Just wish I had time to take on a project like that.

Yun, Your car is the reason I am driving mine. That is the cleanest 100K+ mile car I have ever seen in my life.

Joe, I know that feeling. The only reason I took it apart was I was suppose to have a home office week so I felt I could get it back together in time for Bloomington. Tuesday night at 6PM I got a call that I needed to be on a plane Wednesday morning.

I like!

FYI - I downloaded an IPhone app for my trip home (in the LT-1 car.) It indicated between 95-99 db's. So I had 18 hours of this all in one day. Luckily I had my noise canceling headphones with me!

Now imagine the B&B triflow exhaust.
