Exhaust decision (TOP SPEED or ARK)
 

So I am new to the 370z world, just picked one up. Looking for a good exhaust for a decent price but I want to keep my oem cats. Just wondering if there is a hp difference between the top speed (top speed y pipe too) vs the ARK type 2? Maybe I sound crazy for asking but I have been reading a lot of threads on both and reading mixed results. I am also looking to stay away from any drone. Any feedback or opinion would be greatly appreciated, thanks.

I don't have the Ark so I can't compare, if money is an issue, get the topspeed, you will not be disappointed, it sounds good for the money. No rasp, no drone

Now, if money is not an issue, get the Ark, it sounds good and looks pretty !!

No Drone or rasp with the type 2 unless your planning to run HFC/Testpipe.
