Leaf truck exhaust

[ricurt69]

Does anyone know what the difference is between a coil spring and a leaf spring exhaust system? I installed my present system many years ago and do not recall there being a question. I've inquired to a few suppliers and can not get a firm answer. All the good systems I see are for coil spring only! I really don't want to take it to a exhaust shop. Would prefer Stainless. My present pipes are rusty (really the only rust on the truck)and can't really be tightened down to the mufflers anymore (replaced the mufflers quite a few times). Read somewhere 73 and up pipes will fit.
