Looking to get a 100cel sports cat downpipe fitted to my sti7, already have full TSL firestorm and tsl ecutek remap fitted, will I need to get the car remapped again to accomodate the downpipe or will it be fine?
Any advice will be appreciated.

i think your engine check light would come on. i think you would be best getting a remap to take full advantage of the downpipe as it would be less back pressure on your turbo aswell

 

Hi I fitted one to mine with the same system... and under cruise conditions it threw a CEL due to cat efficiency... out of range, as you would expect.

It will be worth a tweak of the map afterwards, to get most as you will find the throttle response is sharper and a bit more power is always a good thing.
