That's one reason why I recommend either or. Let's be honest the install on a plog and downpipe is a easier install and once you take into consideration the modification that most like to the to SDs.. Then the plog/dp combo seems like the better option.
Yeah it def comes down to personal pref and what the individual is willing to deal with...there has been comments made about how Plog+DP doesn't even compare to SD headers so this is good info for people in the future
