Who has a dual exhaust kit for a 87 El-Camino

[92Camaro]

Looking to buy a dual exhaust kit for my 87 El-Camino. Who has bought and installed such a kit. What make, where did you buy it from. What other problems will I encounter other than the x - member ? I want a mandrel bent kit with good sounding mufflers. This is a stock 305 with a Q-jet.

Thanks for looking,

Ron 92Camaro
