Aftermarket parts... Input and advice :)

Howdi chaps, me and a friend of mine are currently machining and fabricating parts for performance street cars and the such and another friend has joined in with his f360 which we are using as a test mule to make some aftermarket parts ranging from twin turbo kits and lots of carbon fibre goodies...

Our first job is remaking the exhaust system, now we know what people want on cars like golfs and corsa's but were not sure what you Ferrari owners are into...

Now we want any and all input and I'll post pics along the way of our progress so let's hear what you think and what you guys want starting with an exhaust system!

Many thanks
