Bought for my soarer project....
genuine greddy

has a small dent in the bottom...does not affect performance...had it tested to make sure no leaks or flow problems...purely cosmetic....
brand new was $799 on the greddy website...

2.5" inlet/outlet meaurement
greddy rates it to handle up to 400 to 450 horsepower at the wheels...

i bought it for $600 8 mos. ago, but i'm selling my car now, so don't need it...
my loss, your gain... $350 o.b.o.!!
