yes they took off the resonator. im not sure of the tip they used but i will find out. i was trying to use my existing valor tip, but my friend at the shop said it wouldn't work well.
i just got off the phone with my friend from the exhaust shop- hes not sure of the exact munufacterer of the tip. he gets them from a stainless steel dealer that deals with shops. its a 4" oval tip thats welded on.
