Premium Member Tazmool Posted May 19, 2020 Premium Member Share Posted May 19, 2020 Hello Everyone, Something I have been wondering about, The T7 has the catalytic converter in the header, to get rid of it (and remove some weight & restriction) you would need to replace the header pipe. Has anyone replaced the header? (is it possible to do this with out removing the radiator?) What is the weight savings? (if any) If using the stock muffler, did the exhaust noise level go up? I'm guessing an ecu flash is necessary to compensate for the extra flow? Any other advantages to doing this? Any thoughts and experiences welcome!
