x2 on the bends, they will hurt but not much on a stock 250.
A loooooooooooong glasspack works good on a truck as theres room for it and the length makes it mellow and quiet out the back. Just don't get the style with the louvers sticking into the flow. My other favorite for a good cheap muff is/was the Walker Super Turbo aka Sonic Turbo, same power as glasspacks but quieter, just a little healthier than stock.
I hear ya on the cost, its easy to end up with more in the exhaust system than in the motor itself!
