i have the Tsudo n1 catback, and let me say i love the sound....its not to loud

 

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.

that n2 sounds nice how much for cat back??

 

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.

We have item listed www.arkspeedracing.com
