Actually the full kit is ¥837,900, about $7,758 at today's exchange rate. Not installed.In my opinion the kreisseg is the best. Not only the sound is great, very F1 high pitched, but you can switch between "Normal mode" (thru the catalists, resonator and muffler) and "Sport mode" (straight from the manifold to the back!).
BUT, it costs over $5k... not installed.
It's hard to beat the Larini's price.
Send them an emailThose sound great, but those $'s are hard to justify. I can do Larini, FD's springs and have a few $'s for whatevers next. I'd love to hear the Fuchs if anyone can has or can find a clip....
