Front Down Pipe

Posts: n/a
I saw it on Hiro's site and he claims that it will add 10 hp yet keep the stock exhaust sound to the same. Does anyone have experience on those? What is the pros/cons of those pipes? Will I lose power at low-end and gain power at high-end? Thanks!
I think the exhaust system on the 400/430 is somewhat different from the 300.
That downpipe I've asked Hiro, he said it's still in development but will be released soon.
It should add more power to the high-end, probably lose low-end, but that's for smaller displacement cars (3.0 liter), I don't know about V8 GSs.
