Hello everyone.

Recently bought a 04 st 170. I'm looking to make some upgrades for more power, but not sure where to start. Any ideas?

 

Depends on your budget and what/how you'll be using car!
For starters K&N 57i,Exhaust and decat/sports cat and a remap!

Then theres the throttle body route or turbo route but for these you'lle also require aftermarket ecu like /megasquirt/omex and on and on lol

 

Bare in mind though that these cars are juicey on petrol as standard!
