As you know im trying to go rat look, so dont wanna spend big money on an exhaust.

I have a choice to make after the nct, should I
1. Remove the centre silencer and leave the backbox.
2. Pretty much the opposite?

I have no backbox right now and it causes a lag at low revs when i put my foot down because there is no back pressure which is normally caused by the backbox, so will this be the case if i remove the centre box and leave the backbox in. Thanks for reading.

Remove the middle box and leave the back box on

The lag is lack of back pressure, only diesels can run without any silencers

I wud put a straight thru mid pipe on
