OK i have the adjustable borla exhaust tht came with my z28 i just bought, but i have NO idea how to adjust it, becuz its kinda quiet and i wanna open it up a bit. Anyone kno how or have any links, i tried searching butt came up with nothing.

 

Right side exhaust tip has a removable baffle between it and the tailpipe. Unbolt tip from tailpipe, remove baffle, and bolt tip back on .

 

just unbolt the pass. side exaust and remove the plate, and install the new less restrictive plate and bolt back together, borla sounds badass wide open!!!
