Looking for single exit Exhaust and down pipe !! ready to buy!!

I have been going back and forth between ordering a system or having one fabbed up custom. Well the exhaust shop I went to pissed me off so im going to be ordering a system now. Ive really only looked at the boosting performance system and the takeda by afe system. I really wish hks had single exit system for this car but seems dual is all that is available . Has anyone gone single exit on here yet? If so what system did you go with ? and any additional details would be appreciated. Also what downpipes do you guys recommend or have actually installed already. Thanks in advance !

There really isnt too many single exit exhausts and the big one Tomei is taking their sweet ass time for their one.

This is the only one I came across
Boostin performance

With all that's out I would only consider the Boostin Performance with the 4" option and pair it with the ETS 4" DP.

Suprastore and Mapperformance have their own single exit exhausts too.
