shorty headers
TTI makes shorty headers.
Dougs and TTI make longtube headers that dont wrap around the steering centerlink.
Shumaker makes some tri-y headers that dont wrap around the steering and looks increadibly tight fitting from the pics i have seen
Sorry to say but i think Hedman made a misstake on there shortys they seem to dump in a very inconvenient place and angle.
I have not reserched how these fit with a 4-speed more than that both TTI and Dougs longtube headers require some work to make the clutchlinkage work.
i doubt any of these above will conect dirrectly with stock headpipes but a good mufflershop could probably make some adaptorpipes them fairly quick
