Exhaust questions?

[vlj]

Hi all exhaust questions here if you could help me so iv been looking through the forum and iv come to a decision that I'm going to gut the cat out and have a straight pipe to the backbox which I'm putting a centre box on. Am I best taking the baffles out of the centre box? And am I best to unplug the egr valve as I'm gutting the cat out? Also is there a lamba sensor I need to do something with? Thanks in advance mark

The centre box is much less restrictive than the back box anyway so just stick that on the rear it won't cause you any problems.
There's a guide to do an EGR delete but it's basically just getting a small metal plate and putting it in to block it off.

XUDs don't have lamba sensors so nothing to worry about there
