Tuned pipe/exhaust query

Post by Brad Larde » Tue, 27 Nov 2001 22:45:44



G'Day,

excuse me for pestering you all again but I am after a site (or sites) which
explain the operation of the various exhaust systems available (or not) for
nitro engines.
As I am completely new to nitro engines, I would like to understand the
different available options and terminology involved.

The reason I ask is that I have a new Traxxas Nitro Sport and it's just a
little too noisy given my location so I am looking for alternatives that
don't make the thing perform worse, without spending a million AU$ (that's
about $200 US .....;-) )

Things like - can I use a manifold from another engine on the TRX15....is
there one that pokes out the back of the truck (that's reasonably priced),
can I build my own manifold and pipe ......

TIA.

Regards,
Brad

Try removing the stock baffle's in the pipe ( if it has them ) and try
porting your stock header.

That's not going to make it quieter, it will make it louder if it does anything, which is opposite of what he's trying to
accomplish.

G'Day,

I assume it's called a baffle - it's one of those 'great' plastic things. I
pulled it apart last night out of curiosity and there is what I would call a
baffle that is shaped somewhat like a cone and has 4 holes in it. It fits
towards the outlet end of the 'muffler'.

As for 'porting', is this the same principal as a real car engine where the
exhaust manifold port and the head outlet port are machined so that they
match one another in size and shape accurately ?? If so, how do you do this
on something so small ;-) ?

Regards,
Brad.

That's the baffle, if you remove it it'll be louder.

Same thing, a dremel tool works well for this, but it will void the warranty, and it's main purpose is to improve performance, does
nothing for noise.

use a dremel tool or some similar rotory cutter to do it...

Hi David,

Any website/docs on this more in detail?  I sort of know what to do, my
engine is plain stock, tuned as much as I can.  Is it a case of getting
rid of any casting errors, bits that were never removed in factory?

There is a better sight with a step by step that also has pictures but I can't find it right now, maybe some one else has it.

All you need to do is make the transfer from the engine to the pipe as
smooth as possible, round all the edge's, take away all material that
make's the flange odd shaped to the pipe (E: how's it's squared off then
goes to the round pipe) make that all a smooth transfer instead of a
drop off.
