Might ask CBS, they sell kit car exhausts and IIRC they know about approval

I don't think there's actually any rules about these other than exhaust fumes must not enter the cabin.

Forgetting American muscle cars are side pipe exhausts still legal in UK and are any RR members using them on daily retros ? The early well chromed examples seem the one to go for bearing in mind Thrush side pipes command such high prices. I think my wife suffered with thrush, but no side pipes were involved but non the less she's expensive. |

I think that there are various rules under the MOT, RTA, C&U and so on. They come together that an exhaust fitted to a car is not allowed to be:
- Too loud.
- Leaking
- Allowing fumes into a closed passenger cabin
- likely to cause burns or injury to pedestrians
Other than that, knock yourself out....
There is/was an MOT requirement that the exhaust should be of the same type and pattern as fitted to the car as OEM, but I don't think anyone has ever enforced that....

I had a side exit made up for the old camper and that's gone through mots ok since. That's straight out slash cut in front of the rear offside wheel though and not running along the sill.

In the days when modifying retros was less restrictive side pipes appeared on many cars but its quite unusual to see side pipes other than American muscle or Caterham / kit cars etc. Wonder if the idea just died out naturally as less manufacturers built them as most people opt for tried n tested exhaust systems / performance upgrades and modified to suit a particular vehicle leaving the side pipe variant dead in the water.
I acquired a stainless side pipe exhaust and not sure either to sell it on or work out best fitting method to tuck it under sill / would be great as stack pipe on pick up / 4x4 though

Somehow lost the start of this thread which was to ask if sidepipe exhausts have any legal stuff as far as fitment on passenger or drivers side and to ask if any RR members have fitted one and used one on the road on regular basis ?

I think officially for the likes of kitcars and the IVA test, they exit on the side of the car that the engine exhaust ports point to. But thats more for stuff with very little ground clearance. Mercedes SLR has side pipes in front of the doors on both sides, Dodge Viper has had side pipes in a few iterations, same as AC Cobras and the imitators  Officially on most full body vehicles, the exhaust tail pipe tip isn't supposed to protrude beyond the bodywork, but I don't recall many of the side exits I've seen follow that to the word... |

my Peugeot boxer 3 has a side pipe as standard, doesn't poke out past the sill but is clearly visible, the single silencer has intake and exit on the same size, left hand drive models have the tailpipe on the opposite side.

I originally had a side pipe installed on my Brat, out the offside.
It passed the MOT like that with no issues, I did put a baffle in it prior to the test as I suspected it would be too loud.
In the end I did away with it as it was crazy loud and the baffle was too restrictive, I would like to re-install it but I see no easy way of fitting more boxes in to quieten it down.
I suspect this is possibly why you don't see them more often on modified road stuff.

This has had a few views from the local law enforcement and nothing has ever been said, apart from it being liked... It's reasonably loud, using the original centre silencer, but because the car is open, it's not obnoxious. It's been recommended to run it right the the rear wheelarch just to keep the fumes away from the driver, but other than that hasn't been an issue.  |
