I hope that never happens, I love watching Nitro-burning drag cars.  It\'s a noise you feel.

Liam\'s drag car was 120dB, through 2 mufflers, I will be having no mufflers at the pod.

Yes, exhaust looks good. And intake too :)
Power is nothing without control. Weight is enemy of performance, handling and braking.

My FC WAS 113db once at Cadwell. I had to put the bungs in and be a bit shy on the throttle for the second noise test :). Oh and I got pulled over by the police on the way to the track at half 5 in the morning. Think I woke them from their layby slumber!

I blew the backbox on my RX8 and got 112 db on a trackday.  It sounded immense but I had to wear ear defenders when I was driving it.

We measured mine at 112Dbl when I was on the twins. Although it was 3in straight with a single backbox, which Pip pointed out later on had absolutely no baffles in (blown them all out). Great when the brew is ready for you when you arrive at home :D

Guys at work could hear me coming from over a mile away in the smoking shelter on weekends going to work :D

Haha, ok then guys maybe it will be louder than 110dB with the mega phone exhaust out the wing. So long as it is accompanied by flames I will be happy! Street exhaust will be somewhat tame...... Well sort of.

Wing exit exhaust will be loud!  118 db is my bet!

Liam\'s pp with primary side ports was 120dB with a car length rear exit exhaust. I\'m thinking it will be louder

Might be.  The tube might just act as an amplifier if there aren\'t any baffles or resonators in it.  It ain\'t going to be quiet either way.

The misleading thing with the DB scale is it is exponential, so 120-121 is a lot. It\'s something to do with air pressure?

Decibels are a complex unit.  They are logarithmic, so they increase exponentially.  An increase of 3db effectively doubles the sound energy.

Personally id find that level of noise distracting like  direct sunlight in the eyes...ok for the strip but on the road man that would grate after 5 mins. Flames always good though.

I think he has plans for a dual solution. One for the road and one for the strip.
