hayward & Scott + remap
 

anyone put a turbo back H&S system with their race cat on a 2014-> wrx sti and had a remap (poss with a panel filter too?). what were the gains? thanks!

I have a turbo back H&S system with race cat and panel filter.
2009 STI JDM though so not very helpful. 64bhp over standard 300bhp after remap.
Very happy with the exhaust.

being fair the gains are a bonus, but typically you need a remap to stop the error codes coming up, so the bhp/torque gains are just a side effect.

i track the car, and am wondering whether there is enough bang for the buck in changing the exhaust and getting a remap, so would definitely do either both or neither
