I personally find it kind of cheesy and wouldnt be caught dead with any on my exhaust system.

Its not cheesy if you need it in your system; plenty of turbo kits and high performance cars run them. Keep in mind that flex pipe is supposed to help relieve some of the vibration from the engine movement...without them there is no flex point on the exhaust, especially if the other portions of the exhaust are hard mounted or welded. This puts the stress of the engine movement on the exhaust manifolds, and you crack them. Not cheesy at all...and buying the good ones helps.

good point, I guess I've just seen too many Redneck trucks that went a bit overboard with the typical part store sections of it.

Any good muffler shop will carry the steel braided ones that are factory on imports. I have used these and loved the setup.

They help keep stainless steel systems from cracking.
