Got mine dried overnights and flew this evening. More power and 1/2 the noise as the black can. Also seems to accept needle changes more responsively than the previous mufler that didn't carbuerate as predictably. It also didn't loosen any

Good muffler, thanks.

Thanks again Chris, pipe arrived yesterday arvo.

Have there been any reported issues with the mounts cracking?

cbergen · 02-26-2010, 08:11 AM

Which mounts? On the rear mounted pipe or the side mounted pipe?

We've had 2 reports of the side mounted pipe cracking at the joint, both replaced by Zimmermann. He has suggested a rear brace of some kind, a strap if you will, bolted to the frames.

vinver · 03-01-2010, 04:08 PM

It's a rear mount, (NOT the one I bought new from you Chris, I haven't installed it yet) but a used one I took in a trade. Hairline fracture starting where the tab meets the cylinder. Just wondering if it is an inherent problem in this type of muffler (I've read where the MA muffler of this similar style has had cracking issues)

I am resurrecting this old thread to ask:

Am I right that the spark plug cannot be accessed with the rear Zimmerman muffler mounted in it's place?

Dimitris

cbergen · 02-02-2012, 08:25 PM

Correct. You must remove the muffler, NOT the manifold, to access the plug.

Cletus · 02-03-2012, 05:51 AM

Are Zimmermann rear mufflers for the Intrepid Gasser available? .....Got a flying buddy that's fixin' to purchase an Intrepid EB gasser kit next month. Tried e-mailing Zimmermann directly but only got an auto-response saing they will get back to me.

cbergen · 02-03-2012, 09:16 AM

Unfortunately we haven't been able to get in contact either.

8mm man · 02-13-2012, 07:15 AM

I have e-mailed them alot with the same responce ( we will get back to you soon ) that's been abought 7 mounts now.. That's bullsh**!!!!!!!!!!!!!!!!!!!!!!!

cbergen · 02-13-2012, 08:59 AM

I have someone local to me that apparently is in contact with them. I requested that they forward an order for 10 rear mount mufflers.

We'll see how far it goes...

Cletus · 02-13-2012, 05:34 PM

We're good for at least one here in the Caribbean, notwithstanding I did find a used one on the market which I've booked for my buddy who's ordering his Intrepid EB next month
........I just LOVE mine!!!

gcms · 02-13-2012, 09:11 PM

Make sure you keep me down for one.

Pinecone · 02-14-2012, 12:48 PM

If you can get them, I would like a side mount version.

8mm man · 02-14-2012, 01:49 PM

Put me down for one!!!!!!!!!!!!!!!!!!!!!!!!!

cbergen · 02-15-2012, 08:53 AM

They changed the side mount version, moving the stinger (exit pipe) forward to the point that it sticks out the side of the canopy...
