i have a question. do you not want a down pipe because one person had problems with theres?? if so there not all that difficult. mine come off pretty easily, and when they are installed right there hardly even sound any different. even with no cats on an off road down pipe. i think the other guy has an exhaust leak cause it shouldent sound like that. if i can find the video clip i will show you how it sounds. its a 9 min video so you can hear very distictivly and even while hes reving its BEARLY any differece. i dont think you should detour away from a down pipe because one person is haveing problems with them...
