hi guys

i own an st170

mods are

67mm throttle body
180 degree thermostat
10 mm ht leads
ebiak suspension
engine dog bone stabiliser mount
gear stick extension
clutch masters fx250 clutch
clutch masters aluminium fly wheel
aem cold air intake
motorcraft copper plugs,
aem wideband air fuel ratio
sct custom tune
shell v power gas

Im getting some more tuning done, and my tuner said that i would benefit from a high flow sports cat, and bigger flex pipe

and a lager 2.5 cat back exhaust, but im really stuck on witch exhaust to choose,

i do alot of early morning driving, so i want it as quiet as possible, also, im 29 and ive gone past the stage of wanting race car noise

can anyone recommend an exhaust system that goes well on the st170

i like borla, but its pricy, and only available in the states

any help appreciated
