I wouldn't go bigger than 2 1/2". Mine were done by a local muffler shop 5 yrs. ago for $250. I supplied the 3 chamber Flows which cost me about $120 at the time. I use 1 1/2" primary Tri-Y headers. My whole engine is biased toward low end torque (350 lb./ft at 3750). This combo works well for me. 2 1/4" may work just as well. My system is NOT mandrel bent, so may fuction like a 2 1/4" system anyway.
