The engine is a 250ci inline 6, all stock except for a stock GM TBI, Clifford intake and Langdon's Stovebolt 2-piece cast iron headers. The engine is followed by a th700r4 trans. What matters most to me is low/mid range torque and power. I also want a single line exhaust.
What is the best exhaust pipe diameter for this?
Also, any good idea for a muffler (rather quiet, no drumming noise)?
Thanks!
