Motorbike exhausts on cars

[reanimation]

Pondering this as an idea for the MR2, is it a good idea? rear silencer, linked up to a custom bend of pipe?

It'll be lighter, cheaper (?), and simlpler, and look pretty cool/different, an hopefully release a couple more ponies.

What do technical bods make of this russel type mad cap idea?

Cheers

OY!

LOLz!

I want to do something like this:


to my fasty using some bike 'zausts

I reckon it makes sense if you know a firendly fabricator and can get hold of them at a reasonable price - they aren't cheap...

[Russell]

On the bay bike zausts don't go for much, maybe just a wait until you can get a pair

I bought a pair of chrome bike exhausts some time back with the intention of fitting them to my car. The bore looked about right so I snapped them up for fifteen quid the pair at an autojumble.
On closer inspection, inside the cans, the bore had a reducer and looked pretty restrictive so I ditched the idea, slung 'em on the bay and made a small profit.

I'm sure all bike silencers aren't like that, but it's worth bearing in mind when shopping around for some

[trg1984]

do it, my dad's been sticking bike exhausts on cars since the 60's. he swears by it

[RetroWarwicK]

i picked up a NOS suzuki hayabusa end can for £25 (still in the suzuki japan box with suzuki GB stickers on it. plan to wang it on the mini combined with a jetex small middle box. should be interesting

I think the reducers are a way of restricting the bike to 33bhp which you need for learners at a certain age. Even some scooters have this.

They can be removed pretty easily though

[Keefy]

id guess that the 'reducers' are the internals of a stock bike can - as stock cans are, at best, wafty!

to restrict a bike washers are usually used to restrict the air intake not the exhaust. Ive never heard of the exhaust being restricted anyway

bike cans rule tho - ive got a titanium blue flame can to go on the 411/skud

[reanimation]

Would a bike silencer/exhust be too noisy?

[MWF]

Friend of mine did it on his Spit, it sounded like a big bore back box, not too loud or anything.

Sorry Keefy but lots of bikes (that are restricted) are restriced in the exhaust as well as the inlet sides......

The only time I have ever seen "un restricted" bikes restricted on the inlet only was in the case of some of the superbikes when Japan agreed to a bhp max and then they resticted the height the throttles could open

[quantum stop]

i put a bike can across the back of the scud sounds quite muted till you give it some then it comes in to its own real frooty LOL The best type to use are the road legal cans the race ones are too LOUD i live just up the road from quill i come across a few in there skips now n then ill see if theres any this weekend andy

[Blown_Imp]

Ive got one on the imp, sounds ace!

Its a micron track can for a CBR600 RR, 2" straight through, sounds ace

J

[reanimation]

That would be ace SS/Andy!

propper upgrade one looks like this:


It doesnt need all those bends and all that metal does it?!

bend, into can, pointing out the corner, job done. or something more custom is something is another option...

[quantum stop]

do you want it to come (oh errr) across the rear of the mr2 ie along the valance ?? I would take it from the manifold then cut the box off use a bent S strieght across the back using bobins off a mini andy

[reanimation]

Hmm, I need a close propper inspection, and some 'fag packet' designs I think! ;D depends how much space there is.

Tube down from manifold, with a bit of an S then arranged so the silencer is diagonal and points out the corner.
summat like that, only an idea at the moment, should fit and work though I reckon!





scale could be way off! ;D

[phatphord]

Couple of things...
if you buy a stock (ie suzuki hayabusa) silencer it won't be much louder than an oe car silencer, as bikes need to be silenced from standard too. Sorry to disappoint.
Bike restrictions- if a bike is restricted to 33bhp for licensing reasons, then the restrictors will be placed in the inlet manifold (washers), or in the top of the carbs (mostly on two strokes) to prevent the throttle slides for opening fully. Some production bikes (ZXR750) had carb tops that were restricted from the factory, these could be remedied to provide more power by using carb tops from another bike (ZZR1100 if my memory serves). Grey import bikes from japan can have a speed restriction on, that is usually electric to come on at 112mph (again, from memory).
It is common to find washers restricting power in the exhaust on 2 stroke mopeds and 125s.
Reanimation, using a straight through bike silencer will give you no different a sound than using a straight through car silencer of the same bore,it'll just look nicer (and if you buy a carbon fibre, or titanium one), be lighter. Hope that clears a few things up...oh and do it cos it'll be sweet

[reanimation]

Nice one, cheers for advice. saving weight, making sure gasses get out easy hope fully making a litle bit of extra power would be great, so would the look of it. if it sounds good too i'll be very happy.

only other alternative is to get a custom 1 piece made up in a similar design.
