Money well spent. (got my cat-back done)
I got my cat-back done this last weekend, and WOW. It solved so many of the problems I was having; it no longer over-revs when cold like it did, it doesn't hesitate at 45 like it did, and it idles smoother. It also seems a lot more powerful, I know that exhaust doesn't add huge power increases, but my exhaust was bad so I gained back a lot I never knew I had and got an increase. I love it...when the guy had my car I kept thinking to myself "$300 for this whole deal, I hope it'* worth it." Boy was it ever worth it. Also I must thank you guys for all the info on these forums, I found the right muffler size on here and I decided to go 2 1/2" thanks to you guys.
EDIT: Now I really need to do my intake so I can get better gains out of it.
