anyone experiences with these header that replace the cats also. it very tempting...lol...they currently out of stock so it seem like lot of peepz buyin it, feed bak please

 

If it wasn't such a pain to sell the car (take off headers to be legal), I would have bought the Xerd. Long-tube headers make excellent torque. If you can get them and are going to keep the car a long time, I say they are a great choice.
