Too Loud

[stush]

What would happened if I wadded up some steel wool and then put a Vortex cone in. Cone would keep the steel wool from flying out and may reduce sound further??. Any idea if the steel wool would melt from the heat?

Go to the following Thread and contact Mike, his posting


" For 1 day I wish I had quiet pipes. Borrowing a set of trapps and heat shield for the exhaust that my friend just went through a couple of weeks ago and had no problems. He's got a 427 SO as do I but mine is stroked. I'll update everyone on here. Tell your friend if he wants to meet me there @ 7:45am (I know loooonnnnggg day) he can and at least see me go through the fire first."

Connecticut: Registration, Inspection & Emissions

Bolting on the trapps as Mike suggests might be an alternative, but I am not aware whether Mike passed his inspection. The CT DMV standards are " Maximum Permissible Noise Levels for Vehicles "

Are glass pack mufflers legal?
" Per Sec. 14-80a-1a through 14-80a-10a of the DMV Regulations for "Glass Pack Mufflers" it is based on the loudness of the vehicle measured in accordance with the DMV Regulation. The loudness is affected not only by the mufflers utilized, but also by any engine modifications. There can be two different vehicles with the same exhaust system, however, they may have different engine modifications. One of the vehicles will pass the noise level measurement test and the other vehicle may not. "

Within the specs are the specific measurable standards which need to be followed when measuring the dB level and the actual dB allowed:

Sec. 14-80a-1a through 14-80a-10a

If the measurment was taken within the enclosed inspection lane, my guess it would be louder than outside, due to the sound bouncing off the walls. If I can find the CT DMV web link again for the SEC. mentioned above, I will post. I " think ', but am not sure , the Vortex cone is more effective if placed closer to the primary extentions and before the muffler. For this reason, the trapps might be a better starting point. The point of the cone needs to be inserted towards the engine.

Stush, use the follwing link and scroll down to the reference on " Are Glass Pack Mufflers Legal" There is a link to the pdf which contains the SECs I mentioned on Permissible Noise Levels. The question might be if the Inspectors followed the correct procedures in case the trapps or other modification does not reduce the dB level.
