Emailed the above yesterday regarding replacing my centre pipe on the WRX-S.
I'm not interested in power at the mo. Just want a bit more noise. My question was, could I fit a straight through centre (sticking at 2.5") basically just no resonator, and a Cosworth panel filter, without having to remap. Mine is already 252bhp as standard, so a map wouldn't really gain me anything, and for the cost including the initial licence fee. It's just not worth it.
Ecutek say that I wouldn't get much if any power increase (I know this already) but stated that "the boost can go up by changing the centre pipe which is unsafe"
Andy said this may be the case but as I still have the factory down pipe and cat in place I would probably be fine.
Just to be cheeky I replied to Ecutek, (as on their website they claim responsibility for the Prodrive map on the WRX-S) my question was, because the Wrx-s in effect has an Ecutek map from standard would I not have to pay the initial licence fee? Lol
Nice try but basically no!
