Ok i just got upper and lower control arms and was looking at the install. The muffler is in the way of the lower control arm does that cat back have to be removed or atleast unbolted and pushed to the side for the install? Also i was taking a look at the quad shocks and one of them is completely covered in fluid does that mean that its pretty much shot? What do the quad shocks do exactly? And on a side note.. I need a new cat back because i have rust holes in the tail pipes. The original owner just had 3 chamber flows welded in the stock exhaust. I want to open up all those restrictive parts of the exhaust that bolt up to the off road hpipe. I was looking for a catback that WAS NOT any louder then the 3 chamber flows but didnt have the 2k rpm drone. Can anyone suggest something? Possilbly with 3in tips. And if anyone has our knows where there are some sound clips of the exhausts? Thanks
