A dynomax 14" Long x 10" wide, 3" inlet/outlet Ultraflo Muffler weighs in at 14lbs Each per my bathroom scale.

And i definetly like the fact that i see look in the inlet and see out the outlet ;)

smile.gif I had my system pro installed, I spec'd the parts. The guy hefts this huge, heavy 3" muffler, and peers right through it at me and says, "these aren't going to be quiet!" Au contraire!

At least yours are 'lightweight'!
