Selfishly, I'm looking into investing in headers and I want all of your advice. I'm far from an exhaust expert and only know enough to be dangerous. I'm interested in headers to restore some recently lost power from a small billy lift and slightly larger tires. I've researched that headers are a good way to regain some of that power.
The questions are:
What route do I go, short or long?
Where will these different applications help give or take away power?
Do most people go with long tubes just to avoid the welding required for instal?
What brands/models have been well-performing products?
