Building a better “Mouse Trap” has always been a dream of fabricators, inventors, etc. The old spring loaded mouse trap does its job and serves its purpose alright but the question has always been, “What if I could build a better one?” I think the saying goes “Build a better mouse trap and the world would beat a path to my door…” or something along those lines.

I know that none of you have ever put an exhaust system together on your pride and joy only to have it leak, sag, fall off etc. The old trusty ‘mouse trap,’ ‘er exhaust clamp we’ve all used serves its purpose but it isn’t ideal. The alternative is to weld the exhaust system up to prevent leaks which creates other problems like, what if you need to take it off the car? You end up cutting it apart to remove it and then what?  Build a new one, weld it back together?

Have you ever had your brand new headers leak at the collector after only a few days? How about the bolts vibrating loose? How about scraping the collector flange on a speed bump or driveway, fumbled with the bolts, washers, and nuts to get a tri-bolt collector bolted together? No matter which way you turn that collector flange there is always going to be one corner either hanging down or it will be up on top making it difficult to tighten up those three bolts evenly to prevent leaks.

There is also the “ball and socket” type system out there but as the exhaust expands and contracts, it loosens, slips, and leaks like the old guillotine style clamp and they are expensive.

A little research by me revealed some interesting information about the Marman Flange clamping system. We’ve all heard of the Marx Brothers, but what I didn’t know what that Herbert “Zeppo” Marx had a company that made these clamps in the 1930’s. They were used in many different industries where leak proof clamped connections were needed. Currently, the space and aeronautical industries use them extensively, even for fuel line connections.

Steve at Get Bent Mandrel Bending had been dealing with all of the above for some time trying to solve these problems. He has invested a considerable amount of money in research and equipment and it looks as though all that work has paid off. With his New to GBE, rotary end former and special dies he had built for the machine, GBE can now make 3” Marman Flanges, in stainless steel or mild steel, to be used with “V Band” clamps to create a simple secure exhaust clamping system that helps prevent the age old leak problems mentioned above, and it looks cleaner is and more compact too. More new dies will be built in the near future to allow other diameter pipes.

You can buy these flanges w/clamps pre-made, for $64.00 per pair or you can have GBE build and install your new systems at their shop. Call 503-607-0443 with questions or to schedule an appointment.
