hi, can someone tell me the change in noise that it will make if i put pipes out the back instead of turndowns. i have flowmasters on right now it sounds good but all the vibration is getting annoying. also, if i were to put an h-pipe on will that change the noise at all? last, how do you guys think pipes out the back look on the stock v6 bumber? i really like the look of the gt bumper but dunno if i want to spend the money for it. thanks,
kyle
