Thunderthud89 Posted March 17, 2010 Report Share Posted March 17, 2010 title and description say it all but somethign else is it's gotta be real cheap. so the easiest cheapest way to add horsepower to a 2004 gp gt Check zzperformance.com I bought a 3" exhaust and Intake for my 98 GP GT and added about 15hp and it sounds badass.. They have all kinds of other good stuff cheap too.. Quote Subs are like titties, They need to come in pairs because ones and threes are just wrong, and larger amounts will always draw a crowd, we all have our favorite sizes, but the bigger ones are more fun to watch move!
