2007 E63 i am getting headers.is it the primary or secondary cats that are restrictive ob the E63?

still trying to decide should i go with just headers and delete the 2nd cats or should i go ahead and buy the headers,front cats and mids system?

thanks

What type and brand of headers are you getting?

Mason,

Unless you need cats, I would advise a combo of headers + secondary cat delete front pipes to extract the max power out of your E63. We can do pretty competitive packages on the SuperSprint headers + front pipes.
