Well the garage just called my check engine light is because I have a cracked manifold and possibly 2 bad O2 senders. But they cant tell till I fix the manifold. So time for aftermarket. What’s a good set of headers to get ?

A cracked manifold will NOT trigger a check engine light. Might I recommend you find another mechanic?

If you have a 2.7L engine, then check out the LC Engineering headers. They have a really well built design. www.lcengineering.com

Yea its for a 96 2.7L. And i think i have a bad O2 sencer too.

URD has some good prices on the O2 sensors:

go with LC header, as for the CEL, it might be only one sensor is bad, one way to narrow it down, disconnect the battery for like 5 min and then reconnect and drive it around, if it comes on within like 5 miles down the road its most likely sensor no 1, if it takes like a day its sensor no2

anyone familiar with Baja Racing Products? www.bajaconcepts.com/bajaracingproducts they have ceramic headers for the 95-01 2.7 for about 225

i have no idea about their quality though.

its the same as the downey, thats actually where i got mine for 180$, only prb is that i only got 1/2 of it, i had to weld a piece of stainless to it, yeah it was cheap, but it was a pain in the ass, i dunno why they do this, but call them, they told me it had something to do with the intro to the egr in 99

thanks ... if it requires serious modification i might go back to my first choice of the LC headers, since theirs is supposed to include everything needed to install and should be a direct fit.

thanks again

Stick with the LC header. The Downey headers for the 2.7L are total crap. I had mine on for 60k miles and it cracked at the collector and leaked where the 2 pieces joined. I trashed the thing and bought the LC.

LCE's on-line store doesn't give a lot of info about the headers ... what amount of performance is gained with them? gotta be like 150 hp right?? lol j/k

Basically the mechanic told me to what to replace the sensors. They think it could be the crack in the header that is causing the sensors to read too much O2 and making the check engine light come on. They told me normally you don’t get 2 sensors at the same time.

A cracked manifold will give you lean codes as incoming air will fool the 02 sensor.Just replace the manifold or header and have the codes erased.
