One of the greatest performance mod for the platfform? Does it rumble? And more importantly, is it worth it?
The exhaust setup on this current setup is ftspeedfactory UEL header.
This setup sounds Unequal length towards the lower rpm and sounds more equal up top.
You can find a catless header here: https://www.amazon.com/CNT-Racing-Unequal-Length-Header/dp/B0743SP4GQ/ref=as_li_ss_tl?ie=UTF8&qid=1536776730&sr=8-1&keywords=UEL+header+brz&linkCode=ll1&tag=8324894-20&linkId=b742f7e4224961be28ca27ea4c1e6986&language=en_US
and something i recommend as well is getting the tune for the header to maximize performance.
