Exhaust legalities

[karlj]

I was thinking of having my back box under the car, stopping at the silencer… so it'd go mani, down pipe very short intermediate then back box

Just wanted to know before I did it would it be legal in terms of safety and mot?

and where would the exit pipe be karl ?

 

[karlj]

The exit pipe would be where the silencer is

 

[frank]

The exit pipe would be where the silencer is

under the rear bumper ? (same as stock)

 

[karlj]

No it'd be half way under the car (where the cat is on post 93 cars)

Second cat on a k11

i doubt if that would be legal karl, it would point at the plastic fueltank , and the mot man needs to shove his probe up eh

Ok cheers frank… can I have you on speed dial cause you seem to have all the answers to my questions no matter how stupid lol

Side exit ftw

i dont think it matters if it comes out underneath the car in the middle after all it goes past the fuel tank anyways and the pipe will get hotter than what comes out of the exhaust(Y)(Y) you may run into probs with the emitions for the mot but there is ways of getting round that

Also running a risk of Carbon Monoxide poisoning, at least exit out the side of the car, not underneath.

As far as the MOT goes,
The pipe has to be accessible to check the emissions (Which means out the side or the back)
The noise emitted cannot be excessively louder than the standard car (No measurable limits but if the tester thinks its too loud you fail)
If you route the exhaust so it interferes with the brakes or steering it fails
Or if the exhaust is likely to fall off you will fail.

Although for common sense reasons its better to have the tailpipe well past any opening windows etc. or you will die.
