Budget-Budget-Budget Brake and Muffler!!!!
That's a better price than I was quoted on the island here. All mine were around $900ish. After I was resuscitated, I kept telling them if you don't want to do it, just say so.
I ended up buying some 180 degree mandrel bends, and sawing out the parts of the curves I needed, and then just welding the pipe up with the old gas-axe. I had a great time doing it, and it only took all afternoon.
I would have paid someone to do it, if I could have found a reasonable price. I'll bet I still spent over a hundred on parts.
