ok so I have changed out my 95 4x4 1.6 litre 16 valve's exhaust header for a Doug Thorley stainless steel header and jesus pogo stick jumping bunny rabbits it has a power increase.
weird thing was I changed the header out because I had an exhaust leak and it was causing the car not to go and cause it to die out due to not enough back pressure or SOMETHING, anyways replaced the header and forgot the damned O ring between the header and catalytic and it kinda has that problem still BUT I'm slinging that in tomorrow lol.
Anyways now the car runs a hell of a lot warmer(and better most of the time), not overheating but warmer, do I need heat wraps for my new header to chill it out more?
also here is a pic of the new header right before full bolt up


Gotta fix 2 straggling bolts tomorrow as well, nuts got stuck on the studs lol.

The leak may have caused very rich running and damaged the O2 sensor, have you changed that? I wouldn't bother with the wrap just get all the nuts and gaskets in place, it may have been running cooler because of the richer mixture.

There may be some impact with regard to temps and performance using the tubular headers (over castings). Under-hood temps would increase from radiant heat (at least) and free flowing (cooler?) exhaust temps as sampled by the O2 sensors may affect performance. Not sure if running the Cat cooler won't cause issues (emissions and tune).

Food for thought w/regards to wrapping the headers or not. :)

yeah the O2 is shot, I'm picking up a new one today.
Kinda disappointed I can't just straight pipe the car without it running like poop (live in Georgia where it's perfectly legal since we don't have emissions)

Well I was more so thinking of heat wraps so the entire engine bay doesn't scorch my hands when I need to pop the hood lol.

Well I picked up Brakes, Heat wraps, and a new Speedometer cable.
For some reason everyone OVERPRICES the hell out of the Oxygen sensors that are direct to fit, I might just go ahead and shell out for the universal O2 sensor and sit down and try to wire it lol.

A different spec EGR valve at a minimum on the Sidekick. Not sure if there are other differences or if they even pertain to the Tracker though.

I went ahead and got the heat wraps, can't hurt lol
not sure if mine is cali emissions or not, what's the difference?
I think the cali spec versions came with the cat integral with the front pipe, one single unit from the manifold to the muffler pipe, everything else had a seperate front pipe between the manifold and the cat.

Found the problem actually, loose ground wire to the battery, wasn't getting a complete circuit or whatever electrical lingo.
It still runs a little rough due to the o2 being out but I ordered from rock auto.
And Gigafex, you want heat wraps dude, it jumps up about 15-30 degrees more with the new header. DEFINITELY alot more power (causes RPM's to overshoot due to pissamatic transmission)

Also Gigafex, can you give me an exact listing of everything needed for a transmission swap? I'm wanting to do one BUT I don't know everything I need
(95 1.6 16v 4x4)

I highly recommend the Doug thorley header it's sick and makes the car a tad deeper.

BY THE WAY mine is a california trackick according to the OBD plug in (I tried reading it with a paper clip and no luck, any other way?)

the swap was almost to simple honestly it bolts right in you'll need the trans clutch flywheel clutch/break pedal assembly clutch switch (if you want it in there I simply tricked it and put the neutral safety switch wires together) center console (just the front section) clutch cable some soldier (the reverse light pig tail is not the same on the auto as it is the standard dunno why but frustrating) and a zip tie to keep the ignition lock out of the way (unless you wanna tear it apart I didnt) pretty early in the morning so probably not completely everything but thats most of it

You should still be able to read the codes that way on a 95, its probably the SES function keeping the lamp on.

Heat wrapping your headers will void the warranty and according to Thorley will damage the pipes.

If yall are that worried about the heat, ceramic coat them?

Honestly, it is a non issue though.

The cast manifold holds more heat, the stainless lets more out.

I highly doubt they would actually warranty anything with a header though.

Its the warranty for the header.

I would make up a simple heatshield, something like this one:



Its not a Track/Kick but the idea is sound, its from this thread:
