I have a 2000 426 and looking for the best exhaust to run and maybe a new header as well. I have a White Bros E2, I think it was Stock. Any sugestions, I've looked in the post but didn't find anything. I was Looking at the new White Bros Pipe, the E-2 the one that offer 4-7 more horse power. The one i have now is missing some of the allen bolts, not good. thanks for all the help.
