Original (Tri-Mil) Joe Miller / Bob Spangler design, they punched+ mfg those mufflers in house as well; 1970'>'90s. The old Performance Products sold their product line for decades.

It's not a Bursch, those don't have a muffler flange and they are a 4-2-1 design rather than this one's 4-1 design.
I can't remember now the name I've heard associated with this one. Hopefully it will come to me eventually... --DD |

I think that exhaust system was called a "Thunderbird" style. Don't know who actually made them, but it's not a Bursch.

I'm curious how it sounds. The engine wasnt running when i took everything apart.
I'll probably clean it up and give it a go on the rebuilt engine, its rusted but no holes, etc. |

3) Companies made the same system, and the same 3 Co. Owners were pals;
TriMil >Sebring, Targa exhaust, J. Miller Pacesetter > Monza exhaust, W. Harrah Emerso Ind.* >Thunderbird exhaust E. Emerso *Assets purchased by Patriot Headers (IMG:style_emoticons/default/marty914.jpg) |
