Hey Grimace, definitely post up vids and a review. I currently have just the Gt500 AB's. I am seriously considering ordering the Pro chamber as well as the JPC over axle pipes to finish my exhaust. Any thoughts on how this might sound? I'm am not interested in LT headers or cat deletes.
On a side note, was the price always $339? I thought I looked at this about a week ago and it was only $309 but I could be completely wrong as I'm easily confused.
