I just received an email reply from Ark Performance Inc that they are developing a sedan exhaust. Here is a link to their pics and video clips. There is also a dyno graph on the site.

Not really loving the sound. To each his own I guess.

 

It sounds okay but those design looks exactly like the Stillen for the TD; Fuji for the single...oh well

 

203/194 for a baseline. That is very, very low... makes me wonder.

 

That's what alot of people do anyways... take the lowest of the baseline and the highest of the after mod....

Who would believe that an exhaust alone can give sth like 20 whp & wtq without a tune?
(I used to be one of those who are believers lol)
