...I'm not sure what you mean by not having hangers...

What I meant was, not having the rubber donut hangers. I watched the welder do duals on a Monte Carlo, and he used this small strips of metal with holes in it. He welded on end to the exhaust pipe, and welded the other end to somewhere on the car. I figured this looks more durable, considering rubber can get old. I know it's more permanent than rubber hangers, but I figured a welder can always remove it. Of course, I know very little about welding and metal work.

Actually all of you are wrong.

Exhaust tips calculate directly into horsepower while size calculates into torque.

A bigger can = bigger torque

multiple exhaust tips = more hp

And you people call yourselves car enthusiasts. I laugh, go watch TFATF another time.

Does that mean that a dual with 1 tip per side is going to get me less hp that a dual with 2 tips per side will??

or does it just relate to number of cans? https://www.nopistons.com/forums/pub...IR#>/dunno.gif
