97-98 vs 99-01 header (are you ready for the truth?) - Honda Prelude Forum

Keith · 01-31-2002, 12:35 PM

Hey guys,

After surfin' PreludeOnline.com and reading the debate over the 97-98 versus the 99-01 Prelude header and that the 99-01 header was better designed which gave the 99-01 Preludes that extra 5 hpr, I decided I would get the 99-01 header since I have a 97 Prelude. I used to have DCSports CC headers (which I sold) which I believe helped me get 173.4 whpr when I dynoed it so I know how important it is to have a good exhaust flow... I took greek lude's 2001 headers and decided to take mine off and if there were any true design differences, I would install the 2001 header instead. Anyhow, you know how I am with my digital camera so I snapped away to finally put the 97-98 vs 99-01 header debate to rest.

The header on the left is the 1997 and the right is the 2001 -

Don't let the camera angle fool you. THERE IS NO DIFFERENCE IN DESIGN OR SIZING OF THE PIPES!

1997 -

2001 -

The bottom of the exhaust manifold where the 2 outlets are, look larger on the 97 but I measure it and it's the exact same size of the 2001.

1997 -

2001 -

I was hoping the difference lies in the A-Pipe... I WAS WRONG! 2001 (left) vs 1997 (right) -

And a pic for reference of my old DC Sports CC headers -

Conclusion -
THERE IS NOT DIFFERENCE BETWEEN THE 97-98 and 99-01 HEADER! So if you are thinking about getting an aftermarket header for your 5th Prelude, go for it. One thing I have to say is that the DC Sports CC header design is difference than stock. The exhaust manifold is longer than stock and the it helps to have it coated in ceramic to keep the pipe cooler as well.

Was it a waste of time?
No. When I took my A-Pipe off, my mechanic and I noticed that my flex pipe was starting to rot away and I was definitely experiencing an exhaust leak from it. I decided to use the A-Pipe off the 2001 Prelude and keep my exhaust manifold since I couldn't use the one from the 2001 with the studs broken in the threads. Besides mine was still fine.

Special thanks -
To my mechanic Tony (the Doc) who is the only person that works on my car.
greek lude - for selling me his header!

Cheers guys!

Keith

Can we FAQ this and put this rumor to rest?

Thanks a lot for taking the time (and money) to do that little test... It came at a perfect time for me, Ive been putting off my intake and pullys, and I finaly ordered them today... so I was thinking headers next, and I was thinking I would get the 'for sure 5+ hp' stock 01 headers... but now I will go with DC...

Just curious, with custom catback exhaust, aem CAI intake, and pullys, will I be able to feel a difference in power? Honestly?

thanks in advance...

yea, you may feel a loss in low end torque with the AEM CAI, but you'll feel some pull in the top end.

w0rdie · 01-31-2002, 02:04 PM

Well I know there will be some low end loss with the CAI, but shouldn't I get that back with the pullys...?

What I am saying is basing it on stock, will I see a truely noticable different with intake, pullys, and headers throughout the RPM range...

nuro · 01-31-2002, 02:04 PM

so does anyone know where the extra power in the 2000+ engine comes from?

Yeah u wil....... but for my particular matter...... I didn't notice any loss in anything when I had my AEM CAI installed......... top end was very noticably improved..........

The AEM Pullies will definetly increase low end by revving faster and some other differences.........

Catback should increase top end............

latez.........

Good post Klee. Im sure a lot of people on here have believed differently, including myself.

Keith · 01-31-2002, 02:36 PM

Thanks guys... BTW, I had AEM Power Pulleys, AEM CAI, DC Sports CC header and Apexi Cat Back Dunk exhaust and I got 173.4 whpr.... I didn't lose from any area... here is a dyno map of my Lude (1997) versus a stock 2001 Lude...

Hokester · 01-31-2002, 02:37 PM

Very informative and persuasive, but it doesn't tell us a whole lot. Your costs probably prohibited it, but the only way to put this to rest is to actually dyno both headers on the same car and see if there is actually any difference.

Hmmm... ok you do it then.

BTW, the 97-98 header and 99-01 header is the same part number at Honda...

quite an interesting topic.

in the 99-01 Ludes, Honda added a secret 5th cylinder inside the truck. Its really small though, like a coke can, so it only adds 5 hp.
