Ok, id go to another shop, And get some more quotes, but with a muff and resonator? Plus if youre in Canada that might be right in your dollars, all I can say is.. I've had all the other muffs out there, and they're either too loud, or made like crap.. Like the corksport, theyre Chinese stainless and will rust after a while.. And it's nice to score one used, but the CS weighs 70lbs? Try getting that boxed/shipped to you for cheap.. Maybe you could drive down there and get one directly?
