New cat back....what a difference

Ya...well I finally got around to getting a cat back system I have had in my garage for like the last 6 months put on my car this afternoon.....and let me tell you......what a difference it makes........I love drving this car again.....That stock exhaust chokes that car..... would have to say it makes a good diference in terms of seat of the pants...but that may just be me with my wishful thinking etc......heading out to the track Saturday, we will see what sort of # gains we see out of the cat back along with some of my other stuff done.

I just picked up my '91 RS L03 from having a Dynomax Super Cat and Hooker's Super Comp Cat back, 2.5" with quad tips, installed.
Nice.
