Heat is on ???

Do the heat exchangers need to be removed / replaced with headers, when you've removed the heating and air conditioning?

Simple,....not at all

Nope - but if you are going without heat....why not install a set of headers and get a little bang for the buck?

I done been told its bad to run stock exhaust with the tubes off... need headers or put the tubes back on... i want to go headers but so many options and prices ???? in the mean time cut off the heat boxes?????????
