Mike if you are willing to purchase our Sedan exhaust please give me a call. i will consider your non bias review, dyno runs, and videos as a semi sponsorship proposal.

Please do not take this the wrong way. i respect that you are a major contributor on this board and I feel that your review will clear a lot of the questions floating around here.

Man, I really like the sound of this system, I hope someone can clear up the quality of the system and the performance, especially the midrange gains. I am heading out to training for 7-8 weeks and will be getting something upon my return. Quality is my main concern, yellowing tips, poor welds and so on, then performance is secondary but still important.

 

Ark claim's that their "Ark Grip Exhaust" increases HP + TQ. Have anyone who owns this exhaust notice any gain if any????

According to the information that I obtained from the site:

Key product information
- 07-ON Infiniti G37 Sedan
- All bolt on system.
- All Mirror Polished Stainless T-304.
- Street Performance Spec.
- CAT-Back System
- Duplex Reservoir Tank Flow System
- True Dual Exhaust System.
- Horsepower : Up to 15Hp / 12tq's gain?????

 

I have not had any issues at all. Was an easy install. Sounds great, still shines, no rust around the welds (I do drive this car in the winter), never scratched it on a speed bump or driveway cutout.

 

I just put the ark exhaust on my g37 coupe and I love it!

 

Awesome. Let me know if you guys need anything else
