Hello its me again with another problem with the old L322! This time self inflicted, amongst others the newest issue is i have managed to ground the car, it is of course my wifes fault as i had lowered the car so she could climb in and i set off Without waiting for the car to raise, and rather than reversing and going round i thought... nah, its a big 4x4 so i drove down the embankment in front with all long grass and down to the road.... however i didnt see the huge boulder hiding in the grass just over the edge incredibly it missed everything else and has taken a huge chunk out one of the center boxes which is now blowing, I think the car dropped onto the rock as the scrape starts directly in the middle of the box, I have put an exhaust wrap on as a temp fix I was going to weld a patch on when I had an idea, has anyone cut the center boxes off and welded straight pipes in? I have done something similar on the p38 which gives it a more v8 sound but not noticeable at motorway speed (no droning) I though as the box is fooked, now may be a good time to chop them off and release the v8 grumble however I don’t want it to be too load or droning as the whole point of a range is comfort, I have looked and you could cut the boxes off whilst still retaining the existing exhaust mountings I’m just a bit frightened to start hacking bits off as it’s one hell of a big exhaust to replace if I fook it up! It’s a 2004 4.4 petrol,

You need to check on the new MOT, over here any mod to the exhaust like removing any part is now an MOT fail

Yeah thanks for that, the MOT rules here are regarding noise only, if the exhaust silencers or baffles have been removed it is only a fail if, at the testers discretion it is deemed too loud

You sure that is the case for the new MOT? The rules were laid down by the EU.

General rule of thumb for tester is if vehicle emits substantially more noise than same vehicle fitted with standard exhaust = fail or pass with advisory.
The removing parts bit refers to dpf,s on diesels. Mandatory fail if dpf is removed or tampered with.

That is not my information, any CAT, petrol or diesel, that is either missing or looks to have been tampered with is a fail, a non standard exhaust must have a CE approval number, removing a box from a standard exhaust is also now a fail under EU rules.

According to the mot inspectors manual it’s all to do with noise, the removing of cats will be a fail not because the exhaust has been tampered with bit because the emissions will be too high for a pass, dpfs can’t be touched on diesels but you can alter exhausts as long as it’s not stupidly loud, hence my question, has anyone ever run without the centre box’s, my friend has a tdv8 and that has no centers as standard
