agreement was they were bought in from Japan not made here. Cost in Japan plus post is sub $600. nice profit. you can get stainless ones from japan for the money that guy is asking.
consensus was that these wont make 'real' power, just sound and look nice really.
I have had a pair of thos on my race LC for severla years. Crossover design, I think I paid about $600 landed.
Despite comments to the contrary they are not a bad pipe if your engine is tuned to them. At the time they were a good buy but are showing their age and will replaced this year with some Swarbrick kit race pipes - when I get the time !
