I agree with Shawn on missing that one car, my 98’ gtp is and was one of favorite cars that I have owned I’ve the years, just a fun car that threw everyone off on the performance / fun factor and the interior comfort it had. Best part was working for Pontiac at the time and all the warranty repairs I was able to get covered and parts to replaced / stock piled for later repairs.
I remember talking with Ram Air Tech on a cold air kit, pulley swap etc, and ordering the SLP exhaust.
Had the techs at my dealer do the install all were laughing saying it was a waste to do, they did the installs and the techs were more excited to drive the car then I was.
