wonder if anyone can give me some advice on my 97 impreza turbo uk car. i looking to get a bit more power say another 40-60 bhp and not sure the best way to get this maybe a pipe ? or boost tweak the main thing is i dont want to atrract to much attention in doing so i heard some really loud scooby pipes. any help would be great.
ps does anyone know how much extra bhp i would get by just replacing the front cat and keeping the rest of my system?

 

ive got a scorpion full decat i replaced the back box with a tsl firestorm its loud but people look and a bit more power to

 

Hi Jim on my import sti there's 2 cats reomved both of them and got 32bhp more now running @350+ don't know about the uk spec plus have a jap stainless all the way through don't for get when it comes to the mot you'll need to put the cat back.Some places can make you a part of the exhaust so you can take the cat out then when it comes to the mot you just un-bolt the cover and put the cat back.
