i bought some doug thorley headers for my dakota about a year ago and decided not to install, because i am going to drop a hemi in my dakota one of these days. Which means, i will be giving them to my dad. He has a 318 and i want to install them on his dakota and do a complete exhaust job. I want to do single pipe with magnaflow. What size pipe should i do ? 2.5 in and out ? 3 in and out ? how much of a power gain do you think it will get?

Thanks

David
