I will be replacing my exhaust next month with a borla exhaust, I have read the threads and it seems that by popular opion that i should remove the resonator (which by the way i have no clue what that is) I will have the work done professionaly(of course) but could anyone explain first how hard of a task this is.. is this something that an "exhaust shop" has to do? Is there an extra cost to this and how much...and lastly does the exhaust sound better without? Lots of questios Thanks to all who can reply!!! BLACKS
