I installed my ARK exhaust this weekend and I must say it is quit impressive! The sound is perfect but I was most impressed with the quality of the piece and how well it fit. I have installed hundreds of original and aftermarket exhausts mostly on German cars and I have to say that this is far and away the best fitting of any. Most exhausts are drama queens and need a twink here and a nudge there but not the ARK. Thank you for making such a great fitting, sounding and quality exhaust at a fantastic price. It took all of 45 min. start to first test drive and I coudn't get out of the NSX all weekend. I told my sweetie I had to "heat cycle" it just for anouther excuse to take her out!!
