can anyone tell me what the difference in performance a 4-2-1 vs a 4-1 header would be on the 1st gen xB?

 

sorry, i am unable to answer this question for you but hopefully someone else will. Are you purchasing a new header?

 

yes eventually...have some other exhaust ideas in the works.....BTW did you have a header on your xb with the exhaust i bought from you.....cause im running stock manifold, which might explain why your exhaust is quieter on my car

 

no i never ran a aftermarket header on my car

 

4-1 usually better making power in the top end were a 4-2-1 is a better making more torque at lower rpms.

 

4-1 for stick 4-2-1 autos.........4-1 better for high end 4-2-1 better at lower end

 

not trying to be rude bro, but there was a thread made about this in the 1st gen xb area.....its a main topic....i just thought going there would help also....

 

lol mike, i knew someone was gonna say something like that....im sure there is....i was tired and lazy when i posted this up...didnt think about it till after the fact....yea looks like im going 4-2-1, as i have an auto and i miss the low end torque of my integra / jeep

 

Josh, i have the DC 4-1 in my auto and I love the top end I got, it's great if you do much freeway driving.

 

looks like they already answered your question. 4-1 high end 4-2-1 mid range
