I think Eventually I am going to get the Ark N2. It sounds good and not ricey at all. Plus its a Full cat back and you will pass emissions with it. Dynoed gain with only exhaust was 12 WHP.

12 WHP seems like a lot, is it still the 2 1/2 inch piping or did they bump it up to 3"? Check out speed-element.com. I got my axle back Tsudo system from their website, they ship free with fed-ex ground. They've also got the N1 Tsudo exhaust also. It's a little more pricey, but it's good exhaust either way and wont break your bank!!

I just ordered the ARK dt-s. It should arrive on friday. It seems that not very many people have it, possibly because it's a little pricey and it's pretty subtle looking, but I'll post pics and sound clips this weekend if you're interested.

Please do!!!!

Yeah I agree. 12hp does seem a little optimistic, but check this out:

Unless I'm completely off-base, they seem to be claiming a gain of about 17 horsepower on the dt-s and 18 for the N2. Am I missing something? I haven't really looked for any other dyno charts because I'm not really worried about it, but 17 hp would be awesome.

Ill try looking for the dyno chart. I saw it yesterday when I was searching the N2 exhaust. If I find it Ill post it up here.

I just posted a dyno for both the N2 and the DT-S. Not sure how accurate they are. I'm thinking these results were with an intake or headers or something. But on the product page, they claim a gain of 12 hp for the N2.

YES. We had DT-S and N2 both with Header and CAI, It is our customer TC, Since we did dyno before and after, it is pretty much accuracy dyno run.
