This catless downpipe is less restrictive compared to the factory stock one, it promotes better exhaust flow, faster turbo spooling and lesser turbo lag, hence a lot higher horsepower and torque can be achieved. It can also installed without having the ecu tuned, just add an 'O2 sensor' defouler to avoid the CEL will do the trick.
