Headers worth getting?
« on: July 26, 2004, 08:32:27 PM »
I'd really like to get a few more ponies out of my little 1.6 8V . Will headers + K&N filter be a noticable difference? Eventually I'll rebuild the engine, and hopefully bore it out a little at that time as well as put in a camshaft, but the headers and filter seem like safe bets for before and after upgrades.

Will headers and a K&N help much? Anybody else try them and like them?

I noticed a big difference when I out my header and free flow exhaust on my 8V Kick. On my X-90 I just did a flowmaster exhaust without a header noticed a difference. But not as big of a change as with the header+exhaust.

What kind of exhaust setup do you have? What cat are you using?

I got a 2" cat-back exhaust with a turbo muffler many years ago and don't remember noticing too much difference.

On another note... I have been considering removing my cat, but would hate to fail emissions.

We do not have inspection here, so no CAT ;D On the Sidekick I'm running the Calmini Header, Flowmaster Muffler and 2 1/4" pipe. The X-90 has the factory exhaust manifold, no Cat, Flowmaster muffler, and 2 1/4" tubing.

There is a big differance. I have a basically stock exhaust with cat, but with the old headmann header (correct me if I'm wrong but Calmini bought the jig) and a K&N filter. Only prob is I feel most of the power 3000 RPM and above, so I'll get a Cam with low torque grind to compinsate.

Thanks for the replies... I'll probably order some headers pretty soon.

Now the exhaust... I think I'll make another thread about that :)

The Calmini system is tuned for low/mid power...mine runs out of breath around 5500RPM...you can still bounce it off the redline through 3rd but in 4th and 5th its gets pretty wheezy up there. The most I've gotten out of it recently is 6500RPM in 5th and it took a while to get there ;)

Even with the stock air box setup, putting in a K&N filter is awesome. If you get rid of the air box and go with a performance air intake setup, even better. Mind you, I do a lot of highway driving mostly, so thats where I noticed a big difference. No need to 'make a run for it' up the hills!! Anyway, the header swap is a definate must. 2'' of pipe in my mind is perfect. I would never go above 2 1/4 inch on my rig, partly because the noise is not really what my wife likes so I have to keep that in mind. You are going to see a big difference in performance right off the line (response) and like I said earlier, on the highway. If you are concerned with emissions go with the Dough Thorley header. I had to consider it, but hey, I live in Canada and they don't sniff here! Calmini is the way to go!

No I was joking, the best I can do is around 5.5K in 5th...when I had the stock size tires on I managed a little better than 6K once with a tail wind...it shook something fierce and the speedo was buried, but it also wasn't very accurate with the stock tires. With 215's its accurate but loses that oh so incredible top end rush LOL ;D

Consider yourself corrected.  The CALMINI header is also the only header available that correctly matches the rectangular ports of the Samurai and Sidekick/Tracker head.  Even though the 'Kick exhaust ports are slightly larger than that of the Samurai, only the CALMINI unit covers it correctly.

I got mine to do 90 the other day. there was some wind noise, but it didn't really shake at all. I did a MPH calculation on Wildgoody's website, and my tracker in 5 th gear, with the 5.12 gearing and the 215/75r15s, at 6500 rpm, it would do a little over 121 mph. :o :D
