does anyone have input on the pacesetter black painted headers as opposed to the polished ones and does anyone know what the maximum diameter exhaust tubing is for a 05 cavalier

Dont waste your money on the painted one..The other one has Ceramic coating on it not polished...I belive the piping size is 2 1/4 but I could be wrong..If you are buying it brand new it comes with a pipe to fit into the stock cat you just need to welded it on..Also if you are doing this get solid motor mounts..I have heard that you hedder could crack because the stock motor mounts have to much play...I have had mine for a year now with no issuse and am very happy with it...Also just reuse your factory gasket not the one they give you..And you just use the stock bolts..
