I just purchased a new 04 Dakota with the 3.7 six and 5 speed. I found in JC Whitney an exhaust for a Dakota with either the 5.2, 4.7, or 3.9 and was wondering if it would work with my 3.7? Has anyone started making performance products for these yet? I know they are new to Dakotas but they have been putting them in Jeeps for at least a year.
