just got my hands on a jdm sti7 , and its oooooooooh so quiet it needs that scooby burble badly . want to fit a haywood and scott backbox and center section , but am unsure if this will cause any probs with engine running {ie - spikes or running lean } i think theres a cat and an 02 sensor in the center pipe but im not sure , if so what happens with the sensor when you put a straight through pipe on ? .
i may later on go down the full decat and remap route , but need a few other things sorted first . anyone with a bug thats done this mod let me know your findings , ie was there any bhp / performance gains to be had or is it a case of just doing the backbox for now and fully decatting and rempping at a later date .
cheers in advance .

 

I've just fitted a Hayward & Scott Scooby style (Scoobysport) backbox only on my MY05 STi and it now has a nice subtle burble back!!
