Installed the new Maxspeed headers

[jhandy]

Well it is done, about 2 hours of work. Not difficult at all.
I installed the Maxspeed headers with the 200 cell Cats. Definate HP gains. It reaches redline much much faster and the sound.....so sweet.

I will dyno next week, I wanted to dyno prior to install, but I could not look at the headers on the garage floor any longer.

2002 S, Fabspeed bypass pipes, Maxspeed headers, Che muffler, EVO intake.

This modification is worth all of the 799$ I paid.

I was wondering when the first person would appear that has gone this route. So you like them pretty well? I would love to see the dyno #'s as I was thinking of doing the same for my '01 S.

Now all you have to do is get a new muffler that doesn't have that nasty resonance.

I've grown really tired of my Che muffler over the course of the last few months. It gives me headaches unless I'm joy riding in the country with the top down and running through the gears.

Yes the Che resonance is bad. If I am correct the cause is the two chamber design, So..... I was going to take it to the muffler shop and have them weld a tube that connects the muffler cans, like the fabspeed design.
Fabspeeds seems to be a che with a tube.

The dyno guy is out untill next week so I have to wait. However there is a unmistakable increase in speed. The motor revs much faster.

James, be sure to document what the place does to add the piping and if it works. I'd much rather have this done to mine than pay out the wazoo for a maxpeed unit, which is not guaranteed to be resonance-free either, by the way.

Making that claim requires a LOT of design work that few are willing to do.

Fabspeed definitely uses larger inlet tubes than Che. internally, who knows, but I'd bet they're different.

I think people are getting stuff mixed up.Fabspeed sells multiple exhaust set ups. Althought I do not see their entire cat back set up anymore on their site.

How does their muffler have bigger inlets? I thought the diamete of the inlet piping on the muffler had to be the same as the 2nd cat's piping so the bolt clamps fit properly? (this wouldn't apply if you have the entire Fabspeed exhaust set up)
