so i,m all for anything that will stop it dissapearing for ever. so long as it keeps some of the kick in the pants power delivery of the original. and the screem from the pipes, on full chat. thats a good point would it have expansion chambers, or a dust bin stuck on the side 
as for the smell from the exhast. they could have an oil injection on the top end , a bit like the mazda RX8. and we could run castrol R. 
at the end of the day. if its small light. and has a wicked power band i,ll have one.
just think, no rejetting when you fit them tyga pipes
