Skate And Destroy
Including headers and all the hardware my guess is it's over 125lbs. The 1 7/8" tube headers are shockingly heavy.
Click the link below and read post #3 by Locomotion. He said his 3" system that ends at the rear end is 50+lbs. Figure the tailpipes probably add another 30lbs. so let's say 80-85 lbs for the full system? I responded to the same thread but didn't really give any info. It's funny too because I said I was going to get muffler dumps to reduce some of the weight. Still haven't completely ruled that out yet.
Exhaust weight
Dusters are typically light in the rear though so if adding weight behind the rear axle improves the front-to-rear balance it's probably a good thing. Everything on a street machine is a trade off.
