tunable exhaust

Re the topic on too much / too little noise
Made this to get "noise on demand" The valve to the side pipe is controlled by a lever on the tunnel

Cheers J

I remember being in Clocaenog forest in the 60's on the RAC Rally and the Alpine Renaults would come in to Stage 1, they would switch to open exhausts and you could hear them thru all 6 stages. What a sound at 3.00 am! The good old days!

Amazing what you can do with the skills and a good photo software programme ;-). Brilliant but you should have waited until April 1st.

As far as Clocaenog and the other wonderful Welsh forests, the trick in the 70's was to 'Cherry Bomb' the exhaust. To pass scrutineering we would use a broom handle to jamb 3 large round torch batteries up the exhaust tailpipe (jammed in top to bottom so the gas could still get past the sides but very restricted), once they were red hot they would start to break down and would fire out like Mortars....hence the name Cherry Bomb ;-). I had one blow out in Dolgellau on the Welsh Stages in 77 and it was reported to be 'someone fired an object at a marshal checking the QZ (quiet Zone)' in a local paper apparently........

Happy days.

It probably illegal in most countries. At least in NL any change to a type approved vehicle is illegal, sport exhaust, sport cat, side pipes, throttle bodies, different size tires, chip tuning. As long as you keep it reasonable and safe (and get through an MOT) you get away with it. With the Morgan I always think we get a little more leeway. Cheers J

Hey what's this Collin, are you suggesting this is not real? What makes you think that? If I have any skills its certainly not with photo software. smile

I think the position of the front weld gave it away ;-)....I love it though, when I used to come through to our training centre near Zaltbommel I sometimes used my Harley, great fun in the KennedynTunnel switching off and then on again (to fill the pipes with unburned fuel) the BANG was enormous......just childish stuff ;-).

I love your pipes....;-)

It cannot be...our new AMG C63 has exactly this on the rear silencers when Sport + engine mode is selected, or a button on the dash is pressed.

The control is electronic, the effect is VERY noisy as the engine management computer adds revs and fuel to make the effect even more pronounced, up-change, down-change and overrun.....all result in a level of sound that is clearly audible from half a mile away....

The noise is compelling, addictive and enjoyable... It is, almost, embarrassing (but not quite) and I honestly feel that it should be impossible to select when in a 30mph limit....out of respect for others.

(I wish The Plus 8 did this!)
