flowmaster 10 series 1 chamber

[apowers2k]

whats up everyone, i have 02 gt. i currently have the 40 series flowmaster 2 chambers with the stock pipes and stock tips, i just welded in the new mufflers. i want to make my exhaust louder though, i found these 1 chamber flowmasters, that are supposedly almost as loud as getting straight pipes. i just wanted to know of anyone here who is using the 1 chambers? also i want to know any recommendations, if i should change and get these 1 chambers? im trying not to change much in the engine due to the issues with the warranty and stuff, but i definetly want it louder, also does anyone know if these 1 chambers sound nice, or if they sound like crap? thanks again, you can email me at apowers0@bellsouth.net
