Some of you may know that I recently purchased a new exhaust from japan at the above mentioned company.
this being there website
リアマフラー フロントパイプ センターパイプ 給排気
I have had the exhaust on now for a little while and its now fully burnt in and all I can say is wow!
Travelling inside the car is as refined as a 156 ever was. Road noise and wind noise over powers any noise from the exhaust when on a gentle run. The sound is a bit deeper then normal as you would expect but in no way does it annoy on a long run
Give it some beans and it comes alive!! real nice rasp not big basey tones you get from your average bean cans. It really does compliment the alfa V6 engine
I purchased the front pipe and rear silencer, front pipe is equal lenght and reason for purchase is power mod. The power delivery to me seems smoother then was before and it has added the overrun burble that wasn't present before

The back box was purchased for my audible pleasure.
Some people asked if the exhaust sounds anything like it does on the website. I have made a small vid clip for you to judge for yourself.
The quality isn't the best but I think you will get the picture
This gear isn't cheap, shipping from japan is also a pain, all in probably costs 1.5 times the price of your usual exhaust companies (SS etc)
For the sound alone and the likely hood of meeting anyone else with this exhaust to me is worth it
