Re: Which Headers
Good question
You will get opinions
Logic would suggest a tube header will just offer better performance than a cast manifold type
This is not always true
Besides a 10% performance difference is on the order of 5-10 hp
If you are going above 250 hp you need a tuned system
For that start with 1-3/4” for 10-11” then step up to 1-7/8 for 22-24”
Then into a merge and 2-1/2 exhaust
