i was looking at some of the stuff for sale at choppercity.com and they offer a pipe for my 99 400 explorer/199.00 and a clutch kit for it also at 129.00.ok choppercity tells in their ad that their pipe will run 6700 rpm so a clutch kit is a must right?aaens pipe will run at 6250 for my explorer so will a clutch kit be needed with his pipe?any one bought ant stuff off of these companys before?what shall i do?

 

has anyone bought stuff from choppercity?
