:iagree: Same, it only gets loud if you make it. That's why I like ARK Grip.

I'm putting ArmyTrix valvetronic exhaust sytem on mine. It has an unbelievable sound. Check it out......

^^^ Sounds great, but the sound isn't the the only thing that's unbelievable....................
The price is unbelievable as well :(

Ark dt-s
 

Thinking of going with ARK DT-S - has anyone installed that system on their roadster. ARK states fitment with the coupe only with possible interference from added bracing under the convertible. Has that been an issue that anyone can recollect? Also - anyone with this system compare it to other options out there with respect to sound?

Not sure what they are referring to. There is nothing additional i am aware of and all other vendors make one part: for all Z34s AFAIK. Sounds like they just never had a roadster in to validate and its CYA.

I have run franken exhaust for a while (OEM Nismo, now Nismo/AAM Muffler) and will soon be full AAM SLine). Things just bolt up. :)

Thanks. My assumption as well. Install looks pretty straight forward too.

ARK DT-S Exhaust
 

Feedback welcome on this. I received my ARK DT-S exhaust and have a couple of observations. This is all pre-installation. First the tailpipe finishers look staggered relative to the mufflers. Normal? Does the muffler assembly hang somewhat angled under the car? Also, the welded joint going into the forward muffler looks like crap - should be a smoother transition I would think? I have a message into ARK, but would welcome opinions from anyone who has this system installed as well. Pictures attached.

Definitely message ARK about this, they'll take care of you.

Borla
 

Love the Borla on my roadster - especially with top down! Not obnoxious, but beefy when you get on it a bit.

So installed my system. Left it partially installed for now until I figure out the alignment. Fits not quite as well as I expected. Hangs uneven both in height at the exhaust tips and how far each tip protrudes from the car. With everything loose that system isn't moving anywhere to align it. Any have to put washers under the rear hanger brackets to get their system to fit right? Will keep trying but gonna contact ARK on this. Advice welcome.

Yes, had to add about 8 washers spread across 2 brackets to get my TopSpeed Axleback to line up with the bumper cut outs. Initially it sat too high and made contact with the bumper. Overall, not bad for a $259.00 exhaust and i'm pretty happy with the final result.

Thanks 370z roadster. I'm debating how much I dig my heels in here and push ARK for a refund on this system vs. figuring I'll need to rig any aftermarket system I buy. I've got a message into their sales manager on what I'm facing and awaiting his response. Your system looks nice - like the look.

Quick update. Took 13 washers on one side and 5 on the other to level out the exhaust and get a fingertip gap between the bumper and tips. About a 1/4" difference in protrusion of the tips left to right and the passenger side tip is rotated. Now with leveling the rear section the mid pipes lay on the cross brace which I expected from others who stated the same issue. Some washers there and should fit ok. However, seems too much is wrong here and with the odd weld on the one bend, I'm going to return it. ARK stated they'd take it back and refund with no restocking fee. I still want this system to work, so I hope they have a new batch coming or can find a better solution.

Sorry guys - talking about the DT-S system. If the guys at ARK don't have a solution, I'm looking into Berk or possibly AAM S-Line. Any thoughts on their systems - love to hear them.

Just installed a true Nismo H pipe exhaust and love the louder idle growl and high RPM sound over the stock one. Also noticed much better responsiveness from the gas peddle !
