Two-in-One Exhaust for RD350??

dustDevil · 22nd September 2007, 14:36

Hi guys,
I have seen that its a common trend to get two-into-one exhausts for RDs. It has a wonderfully smooth exhaust note! But, I wanted to know how it would affect perfomance?
The Reason>> Shouldn't the gases released in the pipe by one cylinder interfere with the scavenging process of the other cylinder?
Its just a thought... I'm not sure!
What would be a reasonable price for such a conversion?

You hit the nail on the head with your statement on scavenging.

This mod can, in addition to degrading performance, seriously damage your engine.

I think this might hamper performance as the exhaust flow will be restricted. The speed of scavenging will be slower. The RD's are best kept stock or with minimal mods. I have seen pics of RDs with single underseat exhausts. Looks cool, but the original looks are spoilt.

It will not work properly i have seen one on a bike and the bike doesnt move. its always better to have the original silencers than have a 2 into 1 or get a decent set of expansion chambers from tectrac in chennai.

Don't you think riding a 2-into-1 exhaust RD once would say it all! Though I personally agree with most of you guys! It'll affect the performance for the worse!
Thanks for your inputs!

Trust me RD's sound as well as look good with its original pair of flutes...

Any 2 st engine is not complete without a properly designed chamber..

and there is nothing more sweeter than listening to a RD with chambers running "on the pipe"

2 into 1 chambers are ONLY looks and no go..
