I have been trying to use OEM parts to make slight modifications to my 2000 Accord DX, currently about to get a TL-S front sway bar and 17mm Accord v6 rear sway bar... but back to the topic.

When browsing the Honda/Acura Parts Catalog, I noticed that the 6th Gen Accord header style is 4-1, while the 2.3CL is 4-2-1. Would the 4-2-1 style result in any gains, or would my theory of gaining some midrange to top end horsepower while losing some low end torque happen?

 

Exactly what catalog are you looking at?

Just so you know, the 6th Gen I4 has an F23, the same motor as a CL.

 

I have a copy of the 2002 electronic parts catalog, let me see if I can get a picture up. The thing about the F23, I knew that, that is why I am confused and asking about the header.

 

As you can see, item 8 is not listed on the Accord parts list, however it shows up for the CL.

 

Does anyone else have any ideas on this?

 

they both appear to be 4-2-1. A 4-2-1 header will offer more low-end power. Sometimes certain trim levels of cars have a 4-2-1 header( 92-95 civic ex/si) and the lower trim level ( civic dx) will have a 4-1 header. I do not know if this is the case w/ Accords and Cls.

 

the accord only has a single outlet from the exhaust manifold, while from the pics you posted it looks like the CL has 2.

4-2-1 generally has better low and midrange, while 4-1 usually has better power up high.

why not get an aftermarket tubular header system tho instead of crappy stock cast pieces if you're considering the change?

 

That is what I would do, just gotta wait for the money. My question probably was more out of curiousity.
