Removed exhaust from stock manifolds to replace donuts and fix exhaust leak. The old donuts are fit over a small piece of tubing. Is this right? Do I need these little short tubes? They are 2" OD where the donut fits and necks down to 1.75" and fit down into the exhaust. One is about 2.5" long and the other just over 1.13"(hacked on).
I presume they are to maintain the ID of the donut to keep i from collapsing? I would not think it necessary.
thanks
