Got this to replace cheesy worn out one on a 78 thunderbird! Had zero issues! Length exact size in description!...to prevent riping on ends you hook it up to don't fully stretch out the ends for more durability of securing with hose clamps! I saw some of the bad reviews from 2018...materials of products always improving! Definitely worth the price! Superfast shipping! Arrived way sooner then expected delivery date!

This manifold vent duct pipe is so fragile it can not handle being turned for the necessary bend to connect. It tore with hardly any pressure applied. Nothing but cheap garbage. Not long enough for the intended application which indicated it can be used for 1967 to 1981 models. That is wrong. It would have to be much longer to work. Don't buy this product.

Ordered two at the same time. They were both very different in terms of overall length, build quality, and flexibility. One snapped in half when I tried flexing it, and it was obvious the construction was completely different. It was like a plastic wrapped spiral sheet metal rather than an actual tube. I couldn't even get a single U bend out of it before it snapped. So all in all... this was a giant waste of money. The other piece was.... ok at best.

The product is decent enough. It pretty easy to go out of shape because it's such a thin aluminum. The problem is that the diameter is the exact size as the 2 inch preheat fitting on the air intake and manifold.I had to cut the side of the venting to allow it to slip over. It really should be made to be 2 1/8" so it fits over easily and use a pinch clamp
