How much lighter would you say that a greddy catback is than stock catback. I would assume there would be a difference because the old muffler was heavy and there were two huge resonators on the b-pipe. Would there be a difference?

 

The difference is on the order of a few pounds. Maybe 6-10?

 

yup. at least 5lb difference. Ypipe vs Stock Ypipe alone there was a substantial weight difference/advantage.

 

Thats what i was thinking. 5-10. Nealoc, what have you done for lightening besides the hood?
