Sure, just after I buy the Red Jett Muffler, Evolution releases the Blue Performance muffler for less money. It appears to a Be a Jett Stream in disguise.
It still says Jett on the Cast portion.

I see it still has the JETT price tag too.....

If you ever run an engine with one of these mufflers, you would see that they are worth the money. A Stock Evolution .60NX picks up close to 3,000 rpm over that of the stock Evolution supplied muffler (I have ran two Evo .60NX's with a Jett Muffler and the Junk Stock supplied muffler). You get what you pay for, and this muffler is built second to none.
A Full length tuned pipe will cost you more, and require alot of tinkering, and in the long run not return much more than the Jett muffler.I would rather pay the dollar's and get this muffler, since it is, engineered, tested, and manufactured in the Goood Old USA, than a Tower Muffler. I have Nothing against Tower Mufflers, since I run several, but you do have rework them a little to keep them together. The Tower mufflers will give you about 1,000 rpm over a stock muffler, but one of these does quite a bit more.

Well this is really great news! I am very glad to see Dub Jett get one of his products into the mainstream hobby distributors. This can only do good for both he and us as glow engine lovers because it will help his bottom line.
And personally, I like the blue!

If you are satisfied with 15,000+ Rpm's (Not peak Rpm) running a 10-8, then it would fit the bill very nicely.
The throttle responce with this muffler engine combo is awesome.
Here is my project that is about 90% done.

I just put an order in for the Evo Tuned Muffler. It is back ordered until mid May so who knows when I will get it but when I do, I'll pick up the motor locally.

Why not just get it straight from Jett. That is unless ''Blue'' is your color choice, since that is the only difference.

Will this muffler fit a Thunder Tiger or Magnum .46 engine without mods and give performance gains? What prop and what fuel is benefitting?

H5606-Go to the Engines Manufacturers Direct Support Forum and look under Jett Engines. Bob Brassel is their man there and he can answer any questions.
jettengineering.com is their web site. Look for Jett-Stream mufflers.
I have a Jett muffler right now on a TT .46 and it works well. Basically, the Jett muffler is set for an rpm range. You must prop your engine for that range to get the most boost. Somewhere in the 14,500-15,000 seems best, but I could be wrong. A 10-6, 9-7 or maybe an 11-5, depending on your flight preference usually does the job.
I have run Rossi mini pipes and a Jett on a Magnum .52XLS and it is a screamer. I can't speak for the Maggie .46, but it probably will be, too.
The OS .55AX gets a good boost, but the JBA .56 and SK .50 do not. Their timing & porting is not conducive to pipe boost. The JBA .56, on a stock muffler, is right there with the OS .55AX on stock mufflers with most props.
I use 10% Omega, castor blend fuel and a mix of props, APC, MA, MA Scimitar & Evolution.

MOTORMAN37, have you tried any 9'' prop like a 9x9 or a 9x10? I'd be curious to know what RPMs you get with those two.

Dubb sent this to me regarding the Jett Stream muffler on the 60NX and I thought I would pass it on.

That 12.25x3.75 will rip louder than the sound of the motor!

See, I was not exagerating with my early reports of 15,500 with the 10-8.
Is it just me, or is .60NX look stronger than the Jett .60L for less money (SJ .60L R/C with muffler** 15,000 11x6 $325.00).

From what I know and read here, the Evolution line of glow engines are made for Horizon Hobbies, by Sanye in China.
I have no complaint about the quality of their current engines; especially because they are available for such low prices.
The ASP S.61A engine; which is the true ABC clone of the OS.61FX, is [link=http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=10727]available[/link] for just $60...
It will be snowing in hell, before Horizon can convince me that their Evo .60NX is worth $150; even if it can potentially be upgraded into a $210 'Jett .60L beater'...
Horizon is taking all of you for a ride, with the prices of their smaller engines too...
Their Evo .52 is offered for no less than [link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=EVOE0520]$130 minus a penny[/link], while the internally identical ASP, with the same frame size (the ASP .61 is larger and heavier than the Evo .60NX), goes for [link=http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=10726]just $55[/link].
Yeah. Right!
No-one can convince me that 'robbing your customers blind'; as Horizon is doing with their pricing policy, is 'the American way'...

This is sick!
It seems the only part Horizon Hobbies are making a fair profit on, is ... the JettStream muffler...

If ASP would offer a S60A, I'd buy one. I'm all about cheap!

What does the recommended yes/no mean on Dubb's test report? I am using a GWS .47 muffler on my 60NX and am getting good speed and great vertical on an 11x7 for my 60 size pattern plane.
Do I need to prop down to get the motor within the RPM "sweet spot"?
14800 with a muffler change sounds good to me, I didn't pick up but a couple hundred with the GWS muffler.

I guess you are referring to a smaller-frame version with the 10 cc displacement, like the NX is to the former Evolution .61 engine...
I would also. ...opt to buy several...
