Hey ford fans, i was wondering if it is worth buying a Redback hot dog muffler from a mate who said he will sell it for 50bucks. It is second hand. How much do these things go for when they are new and once I get my 2 1/2 inch exhuast will it have to be a red back exhuast.

I jsut checked on my reciept and I only paid $43.00 for my brand new Lukey 2 1/2" one, so tell him he's dreaming!
