Paging Bob27... Bob27 please report to the SPEED forum.
The Jett stream muffler is bolt and go, no hassles- I enjoy fiddling with pipes but the gain would be small if any.

Kinda depends on what plane you are dealing with, and if the big pipe "looks good" on the plane or not.
The Macs quiet pipe system works real well, and the quiet pipe will keep the noise down well. As noted, you will have to do some bench work to tune it, or ask around here a bit for some info (I think IflyVic had an OS/Pipe setup on his SU-27 that he carefully tuned)
The Just Engines purple pipe is outstanding as well - might be just as easy for your to purchase (I see you are in Aruba). They are over in the UK. Again, a quiet system, and they have a good selection of headers to suit the application.
As Razor noted, the jett-stream muffler is simply plug-n-play. Prop the engine so it turns something over 12,500 rpm (over 13,000 preferably), and you are good to go.

I have used numerous tuned pipes, as well as both the Jett and Ultra Thrust mufflers.
Pipes:
Good: Can tune for different rpms to some extent, can get different size headers, Standard, long, extra long for hard installations.
Bad: Need to tune, need a pipe mount, can blow a coupler.
Jett Muffler:
Good: Bolt on and go, very easy, gains nearly as much rpm as a pipe on the correct prop.
Bad: Must run a prop that gets you into the sweet spot for rpm-13,000, muffler doesn't clear the fuselage on some planes. On a stock muffler, the big part of the muffler is located above the exhaust. The Jett & Ultra Thrust have the muffler centered on the exhaust. If your fuselage is wide, you might have clearance problems.
All that being said, it's awful easy to bolt on a Jett, as I did on my twin engine delta, and gain a bunch of rpm. I was running fairly small props anyway so I just tightened the muffler bolts up, cranked, tuned and launched.
