Interesting to read that Eldo got through Regency with a left hand exiting exhaust ... the statement of 17 requirements from Regency on my car, issued on 6 November 2013 said:

"13. That the vehicle's exhaust outlet does not exit to the left hand side of the vehicle."

My understanding was that in SA nearside exiting exhausts are not allowed on cars manufactured after 2005. I picked up the information manual from Vehicle Services at Regency for Individually Constructed Vehicles (it's dated March 07) and it quotes:

ADR42/.. General Safety Requirements, Section 8 Exhaust Outlets "The exhaust outlet, if to the side of the vehicle, shall discharge to the right hand side and downwards at an angle to the horizontal of not less than 15 degrees and not more than 45 degrees".

I had read on the forum that the rule on left hand exiting exhausts no longer applied, but in the absence of actual proof ... ie sight of a Gov document amending ADR 42 (issued on 23 September2006) allowing left hand exiting exhausts, I chickened out and had the side-pipes on both sides run under the car to additional silencers in the wings behind the rear wheels and exiting out the back.

So does anyone actually have a document that allows left hand exiting exhausts in SA?

I'm going to phone Regency in the morning and try and get a definitive answer.

The static noise test at Regency for V8 cars is not greater than 90db at 3,300 rpm.
My car passed it at 85db (every 6db is roughly double the volume). The test was conducted with one microphone at the rear of the car and one set about half way down the car pointing at the side-pipe. It was done on one side (the right) of the car only.
