I have a new 2014 GT premium track pack car. I want the GT 500 axle backs. I have found out that there are two of them. A single outlet that will bolt right into the car. There is also the 2013 and 2014 GT500 dual axle backs that need the rear valance panel replaced. Other than the looks is there a realy performance / Sound difference??

 

SOUND and LOOKS. Big difference IMHO. Go with the quad tips, you WONT regret it. Here is our setup:

 

I was looking around the forum last night and stumbled upon your car.

I said WOW that is a car well done. It is really beautiful.

How long did it take to install and cut out the rear bumper? Also where did you get the Carbon fiber or did you have it liquid dipped?

 

Is there any Drone with that set up?

The reason I am asking the question on this thread is I really like the Valance on the GTCS adn it has singles. But the look of the duals is much nicer..

 

Thank You Jazzman. There is ZERO drone. We had Magnaflow Competition Catback's on the car prior and those had some drone at 2500 to 3000 rpms. The GT500 quads are mellow low tone with normal driving, and scream on WOT pulls. Love them.
It is real carbon fiber. It is one of the few pieces on the car from Seibon. All the other is TruCarbon pieces. I actually got this one off of ebay as they occaisoinally have some CF pieces on there for great prices. In fact, not too long ago, I saw this exact CF valance sell for $200 one ebay! Unreal. I paid around 450 for this one which is high, but it is a beautiful piece that I think is worth the extra coin.
The bumper cut is pretty easy. There is already a line on the inside of the bumper that you cut along. Removing bumpers front and rear on these cars is surprisingly easy. Scary at first, but once you do it, you realize how easy it is.

 

I got a killer deal on my single tips and mid pipes so that is what I went with. The quads do look cooler. I have not heard the difference though.

 

I have the single GT500 AB and love the sound of it. I have only heard the quad setup on youtube. They both sound good to me.
