i i take exhaust apart there no baffle can anyone tell me if hirobo standard exhaust has a baffle or is straight though

I believe they were open. Sounds like an engine tuning issue. Check you glow plug.
Make sure your fuel filter is not restricted.

What enging is in your heli?
What fuel type are you using?
What are your current needle settings?

The muffler that came with my Sceadu has a baffle in it.

That will increase the fuel pressure somewhat... more fuel to the engine. You might try setting the mixture a bit richer to get the same flow with less pressure.

Like mudbogger2 says, check that nothing is obstructing fuel flow.

Also check that your pressure nipple isnt clogged with gunk.
