Thank you so much for our input guys.. I was just not sure which one to get.. Scratching my head for the past 2 days looking at diff videos on youtube from x-pipe/straight pipe x5's trying to figure out which one to get.. From what it looks I'm shifting more towards the x-pipe from what you guys state... the straight-pipe might be too much.. If anyone else can confirm on the x-pipe being superior over straight-pipes.. I'll get it installed tomorrow.. Again all your input is appreciated..
