I initially made my review over at CR: but figured I would post here since some members do not hop the border, thus this is a copypasta from there.
While the other guy prototyped the NB exhaust, I was the one prototyping the NA exhaust. TLDR; I am very pleased.
For the NA, we have a bit of a different configuration from the NB exhaust. The exhaust by ISIS performance, comes in three pieces, and is still header back. The kit comes with a resonator, the after cat section (which ends right after the axle), and the muffler section. Having the exhaust in 3 pieces instead of the stock 2 makes installation a breeze. I think it took me longer to remove the stock exhaust system then it did to install the new one.
Install was very easy, as long as you know how to tighten nuts and bolts. First, hang the exhaust systems into their respectful hangers. Next, loosely install the hardware. Then align everything, and tighten the hardware down real good!
I was firstly, concerned with ride height. I am by no means "slammed" but would say I am moderately slammed, and have no issues with ground clearance.
The design, and finish is rather awesome. It's been on my car a few months now, and the stainless steel really keeps the exhaust looking good. For those of you looking for an RSR style, this is the way to go.
I thought, with my old manish ways, that the sound might be too loud. I can assure you, it has some very good sound to it. Idling, the car makes a very hearty grumble, on acceleration, it sounds like no other exhaust I have heard; no rasp. The drone is not bad either. I have taken it on highway speeds, and found its not too loud. I do have a hardtop, and am running stock headers, so yours may vary.
Here is some pictures for you viewing pleasure!
Thanks for looking. The exhaust can be purchased through http://www.isisperformance.com or any of their dealers.
