I have too. (2of them) That is the main reason I kept the side dump muffler.
His pitts muffler break easily. Then we get blamed for not installing it right.

I have had poor results with 3 j-tec mufflers All 3 developed cracks and came loose!!!

last year a Joe Nall my Wrap-a-round pitts muffler broke. Al was there from J-tec. He gave me a side dump muffler to use. I was concerned about the noise. After a few passes I was suprised that is was no louder than the pitts muffler. In fact my engine picked up a few more rpms. So I kept the side dump instead of getting my replacement pitts muffler. (Thats Al)
We all know how strict they are at Nall about noisey planes. They have never said anything about mine.
The J-tec is smaller than the Bisson muffler
I run the T-6 prop and it is a quiet prop to start with. . I'm please with the combo. Plus it's FAAASSST!
BTW the WRONG prop is the noisiest part of a plane

Yes I am concerned about that as well that is why I am looking for other mufflers that wouldn't involve a lot of hacking of the cowl. (Have you looked at other options for the one that you're building with the american markings and a G-62?)
Perhaps Jtec's side dimension is less than that of the slimline or bennett.

RE: NEW Top Flight P-40??? 1/5 scale
You guys are really tempting me to get that prop! Ready for maiden. Just have to wait for the wind to calm down this weekend. Ran the G-62 earlier with the Mejzlik 22x12 at around 6,700rpm.
