Help! How can I temporarily make my loud exhaust system quieter?

rivers46 · Mar 5, 2012

In one word, the exhaust system fitted to my 3.9 V8 90 is LOUD! It has standard manifolds, leading into a cherry bomb centre box and then straight through (no silencer) to tail pipe. As you can imagine, this results in a stunning noise, albeit a very unneighbourly one!

Has anyone found a suitable temporary silencer which can be added to the end of the tail-pipe and removed once I have left my neighbours behind? From previous track day experiences, I have seen such things, but can't seem to find them anywhere and don't know whether they'd be suitable for a 90V8?

Can anybody help, or does anyone have any other ideas as to how I can practically and temporarily quieten down my 90 without pushing it away from the village I live in? I don't know how long my neighbours will put up with the noise for!

You could fit a proper silencer so as to not make a stupidly annoying noise everywhere you go and fit a big flashing neon sign on your roof instead saying "LOOK AT ME....LOOK AT ME!"

think you worry to much about the neighbours

nothing better that a straight throw starting up at 6am on a sunday morning to to laning

i would worry about mot time

Not just MOT the law has been for a long while now that a vehicle can not be louder than a similar vehicle with a stock exhaust, A scooby boy got done round here the other month, thus not on MOT but Fuzz and VOSA can have you bent over, Have a look at Demon tweeks they will do silencers with removable baffles as different tracks have different Db limits thus the cars need to be able to suit

Ok, as i see it,
1) It aint no feckin hot rod is it!

2) there is a way that hot roders by pass the mufflers..

There is a couple of ways I know the basic one is Spark plug in the end pipe which is illegal, Running Rich is another way, And A REAL posh way ive seen is a chopped up carb mounted to the zorst pipe so you can spray fuel into the zorst :whoosh:

Whilst driving, leave the car in gear, turn the ignition off, a few pumps on the gas, and then turn the ignition back on (only works with a carb though). Did that in a company van in Trafalgar Square once - didn't half make the pigeons shift en masse, as well as **** en masse too. Somewhat irresponsible, I know, but my workmate was rolling about like the Smash advert Martian which was just as funny as seeing the septics and chinks feeding the birds being covered in guano.

Worked a treat in the Hyde Park underpass too

Yep or a good hard right foot down then quickly off the gas so it goes onto over run then wait for the BANG BANG BANG

:nothingtoadd:

Ok, I know / have seen this, but used with a can of propane via a solinoid gas tap,
have the entry point before the spark plug, running off another boot mounted coil, when you swich the lot on, its triggered by the engine coil via a take off, or run by a spark inducer like that of a cooker or gas fire.

I seen it on a cossy sierra..

B I G flames....

Could be that that I saw I thought it was a choped up carb lol
