After taking in all the information available on s2k ( I think)
I have installed the most quiet single outlet muffler on my S.

It is the stainless oval street version ( with built in silencer) of the Magnaflow, I think
spugen uses the same one.

It weighs about 24 - 25 lbs ( loss of 25+ lbs )
it sounds louder than stock when accelerating and possibly the split second you start it. Well, it does have a slightly audible low tone at idle. I did note more power mid to high range. When cruising on the highway it might be 2-4 decibels louder than stock.

At first I was not sure if I would like the single outlet but now I would not have it any other way. I really like it
It only cost 140.00 installed!

 

Can you post some pics?

 

Nice. Mr lightweight.

 

Yes, If I can get my sister to help me, she has a camera.

 

Hey Rick, Could you post a detailed description of the system under my post looking for updated exhaust info? Did you install a complete system or add a new muffler to an exisiting system>

Thanks.

Bill

 

The cut was made at the Y dropping off both stock mufflers and the guy just welded a new pipe for the new muffler.
He did not change the pipe diameter.

Looks very good!
