Im thinking about putting extractors on my 250Xflow engine. It runs on gas 95% of the time, and I understand that conventional extractors wont stand up to it.
I guess what I want to know
- Is it worth the exercise if I keep the rest of the exhaust stock?
- Will the power gain be substantial?
- Do I really need stainless extrators?
- How much will it (roughly) cost?
And the tires were smoking, like my car that time I forgot to drain the oil out before I put the new stuff in....
