I INSTALLED A BORLA CAT BACK SYSTEM ON MY 2000 Z-28. IT WAS A TIGHT FIT BETWEEN THE HEAT SHIELD BELOW THE GAS TANK AND THE BORLA MUFFLER(ABOUT 1/32" GAP)! DID ANYONE ELSE COME ACROSS THIS PROBLEM AND WHAT DID YOU DO ABOUT IT, IF NOT YA THINK ITS OK!

 

ya my borla is way up there to.. the heat shield rattles sometimes to.. but nothin major as long as my pipes are even lenght and hieght im happy.

 

Mine was tight too, but I adjusted some of it out by playing with the fit. No problems with rattles. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

 

the thing is my only rattles slightly at idle on the ode day.. .. but ya never here it in the car.. if u were standing behind the car u can here it a bit.. my friend pointed it out to me.
