Scz e290 exhaust pipe???

[Termy82]

Hi! I’ve on mi Losi 5ive t with engine Scz e290 a bzm micro pipe that go very well at top end, the only problem is that this exhaust system is very louder.
Question there are exhaust with same performance silenced? If yes can you say me the model ?

with any silanced pipe u will loose a bit of performance.?..will u notice it....?...may b.....may b not?

Like he said silenced will always lessen performance slightly, and you may not notice it. Take a look at the Olimat silenced pipe.
from what I have seen, this one sounds nice https://www.rcmax.co.uk/product-page/olimat-losi-5t-silenced-pipe

Hi thanks for reply do you know if olimat have good performance to rev high ? Because I read in the web site of olimat that have the max hp at 12500 and my engine have max horse power at 15000 rpm

It's a round about number, don't stress over it. The pipe will perform well at all rpm ranges, and honestly the sub 30cc engines need all the help they can get in the bottom end. Just going silenced will knock a tad off the top anyway.

Finally I bought the olimat silenced pipe directly from the factory and arrived me in 26 days. The pipe appear built from a good and strong metal, the soldering are made with high precision these are the photos of pipe mounted
Now I’ll must test performance

Hey mate, it's welded not soldered

I tested the pipe with car on the table I lost 1000 rpm compared with the bzm micro . With the bzm micro my engine made 20500 rpm and now with olimat silenced i make 19480 rpm. Tomorrow I’ll test on the road

To be expected to degree, but free spin test (assumption here) shouldn't be definitive for power output. I'd hazard a guess the low to mid range power should be a bit better with that pipe.

Today I test the pipe on the road. How you say pipe have better performance to low and middle rpm have a constantly power for all rpm but haven’t effect Turbo with lag at low rpm that have bzm pipe . Max rpm on road was 19220. I post two photo the first with pipe cooked and second max rpm

 

[Seandonato73]

Not 100% following you mate. The pipe did better all around? Sounds like the micro was designed around top end performance at the sacrifice of low to mid range. Which would explain the higher rpm of the engine. Did you check top rpm loaded with the micro pipe?

 

[Termy82]

The difference with bzm micro pipe is that micro pipe have a lag time in the low rpm and middle but at top end have a brutal force. With the olimat the torque is distributed on all rpm but isn’t brutal ..this is the video that I made yesterday

Ok, yeah I was expecting that to be your conclusion.

Update: I made a good tuning of engine and now go very well from the bottom to top end go very fast .. on the road with pinion 21 and spur gear 56 my 30 dnt go at top speed of 81 km/h and 19670 rpm .. and on the table 20380 rpm
