Howdy all,
Here in NZ we are lucky to have no emissions testing. While I was at the exhaust shop the other day the owner said I should consider removing the secondary cat to let the engine breath a little better. He would fit a small resonator in its place.
Has anyone done this on their car? Some people have told me I'll need to tune the ECU, others have said it'll be fine.
Thoughts?
Cheers
