Quiet pipes for 50 and 91 engines?

[davew]

There were some mumblings at the field today along the lines that my helis are a bit noisey, particularly the 600.

Both my Trex600 and 700 run with OE Align pipes. The 600 one has been crashed as well so am not sure how sound the bafles are.

If I were to change them, what would be the quietest mainstream pipes I could buy? I don't intend spending a fortune but am happy to quieten the helis down if costs aren't silly.

Thanks

I used to run a Zimmerman my 600. Was a quiet pipe.

I've heard lots of people say that Zimmerman pipes are the quietest but I used to have one on a TRex 600/OS50 and I can't honestly say I noticed it being quieter. Possibly it had a slightly nicer tone to it than some others.

Got a TT High flow 3D on my 55 and it's a lot quieter than the funtech it replaced.

I agree with ross on the gp pipe, its has a smoother and quieter sound than the hatori
