The comptech header is nice, wondering if it will fit an accord.

its hard to tell, it depends on whether the accord chasis has room to clear it. I know the TSX exhaust fits the Accord, so there's a decent chance the TSX header does as well

I check my parts catalog and they look the same but here is what I found:

Accord L4 (all years):
Header: 18100-RAA-A01 (AT) -A11 (MT)
A-pipe: 18210-SDA-A01 (AT) -A11 (MT)

Accord L4 A-pipe Specs:
A01 - H-203mm, L-406mm, W-163mm, Weight-4.9kg
A11 - H-171mm, L-412mm, W-165mm, Weight-3.061kg

TSX (04-05, no info on 06 yet):
Header: 18100-RBB-A01 (AT) -A11 (MT)
A-pipe: 18210-SEA-E02 (AT) -A12(MT)

TSX A-pipe Specs
E02 - H-146mm, L-759mm, W-215mm, Weight-4.016kg
E12 - H-146mm, L-759mm, W-215mm, Weight-4.016kg

To be honest, I don't think they would work on the Accord because all the specs I have on the A-pipe seem to be different, which is not a separate piece on the Comptech headers. Remember, the TSX has to breath a little more than the Accord because of higher compression.
