Topic ... TOYOTA A90 SUPRA ... It seems that the muffler has been released from overseas muffler manufacturers, but as long as you listen to the sound on youtube ... Of course it does not match the regulations in Japan and quite Loud volume. It's not related to Japanese regulations, so we were secretly developing it, so we made a base with the brother car BMW G29 Z4 20i and made a jig in the last blog! I think I was writing. Since I have not yet fitted with A90 SUPRA, I can not write in detail, but as you can see, the prototype is completed and left to be installed on the current car, checked each part, and measured sound & volume I have to do it. I have heard a lot of rumors ... Can I keep this specification? Shouldn't it? It becomes clear after the current car is received! ! What will happen? ?
