Reply to "2 turbo or not 2 turbo"

Todd,

I'll share my thoughts on keeping the Pantera quiet:

Better sound deadening material in the bulkhead & under the carpeting will help. There is a company advertising in Hemmings that sells sound & heat insulating kits, they have a picture of a Pantera in their add. An air filter with snorkels like the oem air filter assembly quiets things down (half the noise is intake roar, it's not all exhaust). Quieter mufflers obviously will help, so will wrapping the headers with heat insulating tape. Double pane rear window glass would help, although it would be expensive.

A turbo sucking air makes a hell of a racket, so it is definitely not a method for noise reduction.

I realize an enclosed air filter assembly & quieter mufflers will restrict the power of your motor. So perhaps 2 air filter assemblies & 2 muffler assemblies, one for street and one for the track, would be a solution for you.

I understand your position. My motor is currently 100% stock. I use the car for traveling. The noise level is already barely tolerable. I'm wanting to up the motor's performance, but I'm not wanting to up the noise level. I'm pondering how far I can go with stock Ansas. The exhaust system Fred Terry built for his Pantera looks interesting.

The motorcycle industry is capable of producing exhausts that are quiet yet allow the motor to make plenty of power, I don't understand why this technology hasn't been applied to autos, at least in the aftermarket.

Those are just the thoughts of this old beggar, I wish I had the magic answer for both of us.
