I was in a parade last Sat behind a 32v Cobra vert, o/r X, and SLP.

It made kids reel in terror and babies cry. Seriously! But then, after the kids were scared, they were like, "YEEEEEEEAHHHHHHHH!"
 
the drone is not real bad,but it is there. the car has a stock h-pipe on it now and i cant belive how load it is with 4 cats. so you guys think the pro chamber is the way to go? over an x-pipe?
