Correctly built tube manifold will outlast a pipe manifold in any circumstance due to bring able to withstand more vibrations

For the unfamiliar, what's the difference between tube and pipe manifolds?

Pipe is rated in schedule and weighs a ton.
Tubing is rated in gauge and is more vibration resistant.

Difference is a lot of weight savings with tubing.

I'll go into details later, but for now I'll just say this - stiff motor mounts and sidewinders do not mix.

I've read your build threads (feel free to relay details in this thread ). I also have a Mase manifold (bought it second hand; no cracks from the previous owner). Was your cracking issue directly related to the stiff mounts?

Many mase manifold owners with stock mounts also experienced cracking.

Due to a design flaw associated with the manifold?

Exactly my thoughts as I have one torn right now. I would expect stiffer to be better for exactly the reason you mentioned. I'd change only the passenger side if it was me as the other rubber side would allow for vibrations to be soaked up. Also I suppose should consider motor rotation direction though. Something to weigh out.

With a flex section in the pipe I would imagine the harsher vibrations are worse if anything but this is simply a guess on my part. If one has stock mounts I'd strongly urge them to get a flex section if they're on a tubular.

Rod ends are your friend with tubular manifolds. Never have had a problem. Gotta anticipate the direction of the expansion when bracing
