I will be putting headers on my 2000 GT in the next week or so. Can anyone tell me if I will need a gasket between the headers and the mid-pipe?? (FYI they are Mac LT's and Mac O/R Prochamber mid-pipe) I have heard that they will be a perfect fit and no gasket will be needed since they are the same brand. Is this true? I believe I may need to buy some O2 sensor extensions as well.
Thanks for the help
