exhaust rattle

[mr_r0bert0]

Ok I just put pace setters lts and a ory and now it rattles heat shields and it sits on a exhaust bracket or crossmember whatever that is... any suggestions on how to stop the rattles... thanks

I have pacesetter long tubes and off road Y-pipe on both of our SS's and I had this problem both times.

As far as the crossmember goes,,,that's as simple as readjusting the pipes and fiddling until you are happy with the fit.

The biggest issue I had with both cars is the other problem you described. Driver side Y-pipe hitting the floor/heat shield area. Everytime I hit the gas it would bang the floor.

I found that when you clearance the crossmember it made it closer to the driver side floor and visa/versa. I only had clearance for one or the other and no amount of adjustment really worked to my satisfaction.

My solution was to cut the driver side Y-pipe both at the header collector and the Y-juction and pull it down about 1 1/2 inches and then re-weld it.

This gave me the added clearance on both cars that I needed for engine movement. Also made it easier for me to access the bung I welded in for the wideband on both cars.

Check the o2 sensor's if there new . Mine rattled to the point where I thoght the flow through cat's blew apart.

well the o2 sensors are the stock ones... but it sounds more like its rattling agianst shit because ive destroy cats already and doesnt sound like that
