So, I've had my Ark exhaust for 4 months so far and personally I think it's one of the best sounding exhausts out there for the 370z..not being biased at all!! Anyway, I know some of you guys are contemplating getting this exhaust because of the tip issue, but honestly it's not as bad as it looks in pictures..just get an extra set of eyes to help you out while installing this exhaust.
Sound
I really can't justify the sound of this exhaust over text or even a video! you really have to hear it in person. The first time I fired my car up with the exhaust, it seriously sent shivers down my spine. It really gives off a nice deep v8 sounding grumble. During normal driving it's not loud at all until past about 3.5k rpm but once you WOT, the car just sounds freakin mean!! almost like an exotic. There was a bit of drone when I first got the exhaust, but after the packaging broke in, it died down a lot which was a big plus in my book!
Power
The first time i had this exhaust put on was at a dyno shop..so needless to say, i got it dynoed. We ran 5 runs for the baseline and ended up at 294whp the highest(Yes, i dont know why this dyno read so high). Then with the ARK exhaust we only did 3 runs and ended at 306whp. I couldn't get the torque numbers for the baseline dyno cause the computer didn't log it for some reason...but the torque for the ARK exhaust was at 253 if that helps. This before and after dyno was also without an ecu reset, so I think I could've squeezed a little bit more out of this exhaust.
Looks
I uploaded some pics for you guys to see. There is a right tip picture and a left tip picture. Also you can probably notice the right canister hangs a little lower than the left, and that is because I have the prototype version. I know the final production exhausts don't have this prolblem and Ark worked really hard and test fit every exhaust that came in to ensure proper fitment.
Also for those of you worrying about scraping, it's not too big an issue unless you're going up a massive speed bump or really steep driveway. I'm lowered on kw v3's and dropped about 1.25 inches in the rear and 1.5 in the front and most speed bumps and driveways i go up, i don't scrape...and this is with the prototype exhaust which hangs a little lower too. So all in all I really enjoy this exhaust and after 4 months of ownership, I am not one bit tired of the sound yet. Hope this review helped some of you make your decision in purchasing this exhaust!!
Also, if you guys haven't seen this yet, this is my car filmed outside the ARK warehouse. This was prior to getting my berk hfc's.
