I got mine from Pypes.It was on E-Bay brand new in a huge box(there's a lot more),it was $126.00,2 piece (sweeeet !!!),and fit my BBK headers like a glove.very nice x-pipe I must say.Check them out.
Most of the Magnaflow stuff is stainless sp they cost more than aluminized versions. I had a magnaflow catted x and it was complete garbage. I quickly got rid of it and got a stainless bassani. It is simply awesome but costs a good chunk of $$$.
