How to TRY to make your bands not leak

Here is a little tip that I learned years ago when I was bending exhaust for domestic vehicles. I decided to try this with a set of vbands on the new 2020 Porsche speedster exhaust that I was custom building and it worked quite well.

I use both your Marman flanges and the machined ones.
-- If I do a machined V-band, I let the tube stick out on one side so the flanges fit tightly. I use original flanges on applications that are absolutely critical, like pre turbo flanges (I have my own custom flange design for those) or header collectors that need angular adjustment and a good tolerance fit. Heavy vibration is another application for the original v-bands.
-- For cheaper exhausts, I use your Marman product. It's superior to any 2-bolt, 3-bolt, u-bolt, or lap joint product, and by a large margin. It gives the ease of assembly from a solid V-band flange, but at a much cheaper total system price.
-- Your flex bellows are good. I dare say they're the best on the market. You pride yourself on the Marman flanges, but your flex bellows are the real ticket.

I’m so glad I found you on TH-cam. I’m amazed at your capabilities. I’m going to contact you soon about making about a 24” 304 Stainless tail pipe with 2 slight bends to form a ‘joggle’ and a final exhaust tip bend to get best exit angle. Lastly, it needs to be flared to accept a 2” OD stainless tube stub at the muffler and have 2, short loops to attach retainer springs. I hope I can afford your service.

I always slid the v ban ove the pipe and use the pipe to do the same thing u did
