I was wondering if anybody could help me with this. I have a 2004 Limited coupe that stock weighs 3084 lbs. I replaced the stock airbox with a DCAI from Rob which felt somewhat lighter than the stock assembly. I also did the Needswings 304 SS downpipes with no cats and an SRT cat-back with 2 bosals in place of the stock muffler. I have also removed my passenger seat. I don't have the stock pieces to weigh other than the seat, nor do I have a means of weighing such items. Does anybody have a guess toward my weight? Thanks.
