Its actually for my missus car ya see and she wants to get a bit more of a growl from it but by removing that centre box she doesn't want it to be stupidly noisy.
She planned to keep the back box and cat in place, anyone done this?
Bit less restriction bit more noise shouldn't fail MOT. Noise level are huge for MOT. Emmisions well only one way to find out shouldn't affect but then again exhaust alone shouldn't fail it and they have before now.
