ID for Expansion Chambers/Tuned Pipes

[Ron Reaves]

Hi guys, when I sold my R-1 and Grand-prix in the mid/late 60s, we were using direct drive and exhaust headers. Now that I am back into this stuff I have accumulated approx 15 various exhaust pipes and expansion chambers. Most of them have no markings at all, of course, the shapes vary, and a few of them have a "H" cut out for the exhaust gases to exit the chamber. I believe, because of my limited experience with these, that I will stick with the basic can mufflers. My question is, Is there any way I can identify what brand these chambers are, and what engines they are designed for, so I can sell them?...Ron

Hey Dave-
It looks very similar to an Adios pipe built by Savin Engineering.

In case anybody cares Savin pipes use 1.5" flex and the header tube OD is 1.375".
I put a pair of really hot 101s onto some kind of post vintage dual C open sidewinder that has an 1-1/4 " x 48-5/8" wide rear axle. I've never bothered to actually run the thing, don't even know what kind it is. I think the pipes are Macos. The Savin Engineering headers on it are for blocks with raised exhaust ports.

Sorry about the delay on the pipe pics. I'm having trouble posting pics. I'll figure it out soon....ROn

OK guys, let me try this with pics... This is two pipes. I have probably 10 that I don't know about. I'll send a few more pics later. I assume they were all used with Macs since I got these with some Mac stuff. I appreciate any help.

Pipe 1: About 26" long, no markings at all, widest section 4.25", next section is 3.375" (1" exhaust outlet hole in the 3.375 section) 1.875" at the intake, 90 deg offset.

Pipe 1-1
Pipe 1-2
Pipe 1-3

Pipe 2: About 24" long, no markings, 3.375" at widest point, about 20 deg offset I'd say, 1.875" at the intake and .875" exhaust outlet on the other end.

Pipe 2-1
Pipe 2-2
Pipe 2-3

I hope the pictures work out ok. Thx.....Ron

Pipe 3 looks like a Kendick

Pipe 5 looks like a Kathy Hartman KH9. it shoudl be very light on the end cap of the pipe.

Pipe 6 is a Gary Hartman blimp pipe.

Hi Rob, Thanks for the info. No, that is not me posting the pipes on e-bay and getting the big bucks....If you guys, need one of these pipes, let me know. Maybe I should keep a few, they just take a lot of space.

Is there an article or source that I can read to understand the concepts of chamber shape/size and their operational advantages?

I have one that has stamped on the end: GEM "OT" What does the OT stand for?

Any other ideas about the other pipes. I'll get better with pics next time I post something....Thx again.

I may be coming to Barnsville in March but not sure. I won't be bringing a kart but this would be my first time at a vintage kart event. I hope it works out.

I haven't heard of much other vintage stuff going on in the greater mid-south area. This is a close as i've seen. I'd like to talk with any other guys in the Arkansas, Tennessee, Mississippi, Alabama, Georga interested in vintage. ...Ron
