99 GTP Borla Cat back w/ high flow Cat SpeedbuiltT Strut Tower Braces front and back K&N filter
I had it on my 03 Monte Carlo LS, it REALLY helps tighten things up, the parts are the same used in the Police Impala's, so I think it would even be an upgrade for a GTP. The price is just right too, I think I got all the parts for around $140 and I ordered through a dealer. The new bars come of course with their own insulators, but I used some poly ones from.... cant remember the place right now, but with those and the bars I think it would be just as effective as any aftermarket solution, plus it would save you money to spend on performance stuff.
