I have read a few threads about this, but have not been able to find the products on the internet. I have a two questions.
1) What is the quietest 3" turbo back exhaust system with high flow Cat? Please include the URL of a dealer if possible.
2) What are the stock exhaust sound levels for Idle and full throttle?

 

Check out the Cobb TBE

hks hi power

 

The problem with youtube is that I control the volume. If stock exhaust is 90db then under 93 is great. If stock is 70 db, then my wife would make me put the stock pipe back on.

 

lol. I hear that. I think stock is 89db.

 

Quoted from here:

Stock Exhaust

idle - 74dB
SAE - 81dB

I run a Works ABM. It's almost as quiet as stock.

The Legalis R is the quietest catback exhaust available for the S2000 so I'm going to assume its the same for the Evo.

 

Tanabe Touring Medallion...bearly louder then stock and meets 93db limit

 

I have the Cobb and its real quiet. I close to Philly Pm me if you want to meet up and hear it.

 

I've heard the hks hi power sounds great not too loud.

 

off topic, but how loud is the greddy tic?

 

The Cobb is not that quiet...

Ti-C is loud but not as loud as Ti exhausts


these are just some off the top of my head
