Laws on boso pipe/up turn exhausts

[enterscott]

On sunday I got this made up and I love it to bits!



As far as I know it's legal

- No sharp edges
- Doesnt protrude longer than the bumper
- Its facing into the road rather than pavement
- Its declared on insurance

But I just want some more knowledge on this just in case I'm wrong and I thought this would be a good place to ask 

Cheers!

What about filling up rain ? Maybe drill a home at lowest point to drain anything that gets in. What about making a rain cap -

I'm gonna drill a small hole at the bottom for it

Rain caps look quite good but Ive heard the rattling of it when idling gets very annoying haha

but if you drill a hole isn't that a mot fail?

I'm sure a tiny hole wouldnt be put down as a fail

"MOT Test of Exhaust and Emissions

The exhaust system will fail the MOT if:
Part of the system missing or excessively deteriorated
A catalytic converter is missing where one was fitted as standard (on vehicles subject to a full cat test only)
Mounting are missing or damaged so that the exhaust system is insecure
There is a major leak
The system emits appreciably more noise than a similar vehicle fitted with a standard system in good condition.
Class (v): Exhaust tailpipe positioned so that fumes are liekly to enter the driver or passenger area.


Emissions

These are checked using specialised equipment, the details of the check depending on the year that the vehicle was first used on the road. Excessive smoking (checked visually) is a reason for failure.

Diesel smoke emissions are checked by using a smoke meter."

Hi, A 1/8" hole drilled for a drain wouldn't constitute a major blow. If you are worried put a self tapper in it for the MOT.

Nowhere does that say having a drain in a silencer/pipe work constitutes an RFR. Most aftermarket quality silencers have a pinhole in the rearmost silencer to allow water to drain so it doesn't rust the silencer from inside out.

I seem to remember the E-type had drain holes on its upturned exhausts....So if its been good enough for the last 50 years or so.... in an interesting aside the first e-type in the uk was sold around the date of my birth....

When I had my Imp I fitted a Sports exhaust system and it was a well known trick to drill a tiny hole at the lowest point of the silencer to allow condensation to drain. It's surprising how much moisture drips out that would otherwise accumulate.

In my experience it's only holes in the exhaust BEFORE the cat that cause an MOT fail. After the cat it shouldn't matter as the same gas is coming out of the end of the pipe anyway as would be coming out of the hole. It's only really a concern to testers if it's structurally unsafe or loud as ####.

love the exhaust ,
