No negligible difference in fuel consumptino.
Still around 17-23mpg like before.

16 l/100km to 12 l/100km.

I guess people's still get occasional pops with oem and mine is more extreme with the secondary cat removed.
How you will do this with the car inspection ( X-pipe welded on with straight pipes)and the emissions test ?(will fail)
Here in Belgium they look under the car and with cats. removal i will fail ?
