I would not bother with an ECU flash after installing S-Line exhaust. My 16M put down at the wheels 445 hp after installing the S-Line exhaust. Stock is about 428 to 430 whp from the dyno's I have seen people post. The car will learn the new flow characteristics after a while. Best upgrade I have ever done, that exhaust is just fricken perfect.
I have heard some have had good success with Evomsit ECU flashes, but I would not do it. If you can ship the car to Evomsit, and also change out the headers to Capristo, then maybe, but I would want my car there at Evoms to make sure everything is tuned properly and before and after dyno's.
