hi all , as above , i have bugeye wrx , i have put a 3 inch decat downpipe on , decat centre and big back box . also put green panel filter on .

will be getting a remap done .

question is only now have the uppipe cat to change , is it relevant ? will it make any difference ? only reason i ask , is that i have read many threads , that suggest it may be hard to change it . as i will be doing it , dont want to become stuck .

so really unsure wether to bother or not . if it dosent have any gains .

thanks simon

I was told the uppipe cat should be removed to help spool up now i have 353bhp 351ft/lb torque on my blobeye

worth doing as far as im aware, the uppipe will limit the amount off boost a mapper can commit to, with out the uppipe cat the mapper can raise the boost more therefor more power. but doing this you will need a remap vertually straight away to be safe

sti uppipes are ok as there not catted but the wrx one strangle the turbo plus its not great having a cat feeding the the turbo incase it breaks up,i fitted a classic one to mine but its not the easiest job

Email or PM harvey with your spec. He can specify and supply you an optimum sized/designed/ported u/p for you to gain max performance/turbo spool-up, etc........
