My Gen 7 is presently undergoing a complete new exhaust system fitment with an expert fabricator.
All new 304 stainless steel from manifold to tailpipe but with the exception of reusing the original cat; confirmed by the MOT tester to be working very well.
I've asked for the the new system sound as legal as the OEM system.
Very excited about it, told them there is no urgency and take the time they need to do a good job, although i think good jobs is all they do.
The picture below is a recent snap on their facebook page of a Yaris GR with some titanium bling;
but look at what's waiting in the background
