Has anyone installed headers on a LT1 and a LS1 car? I've done it on my 93 T/A.....Is it harder on an LS1?

nope, easier.

[Y2KPewterSS]

Lots easier install on an LS1.

Lots easier install on an LS1.

I agree I have done both

I installed my long tube headers and everything went smooth; except when I went to plug the O2 sensor extensions in. The extension wouldn't fit in the O2sensors on either ends. So I modify the entension's plug to fit the O2 sensor. Well it went together and there was no Serivce engine soon . I drove it for an hour and parked it. An hour later I started the car and now the light is on. I made sure the extensions were plug in and the light was still on. I sanned the computer and 3 codes came up. 154, 154, and I think 174. No O2 sensor activity and a lean exhaust. Whats the next step?

I ordered gm gaskets and what a big difference. I only paid $19 with my discount at work. Here are some pics of the gm gasket and the ones that came with the headers.Top gaskets are gm.

Did you buy the gaskets from a GM dealership?

Sure did

So the gm gaskets are much better gaskets then you think? Just curious before I put my headers on.

Do you have cats?

Do you have cats?

yes

['00_Cucui_SS]

Nice, that's gonna sound awesome!

[INMY01TA]

Sometimes with long tubes the cats dont work well enough with them being further downstream in the exhaust. Get some 02simms or get the codes tuned out.

Here's a sound clip with my digital camera. The sound quality is not as good as my video camera, but I'm having trouble loading it up .

Cool... if you copy the "img" code and paste it in here you won't have to make us all click for pics.

good luck with the install.

Nice vid, thanks for posting that. Sounds very nice. Are you happy with the sound and power increases you achieved?

Thanks. Very happy with the sound. Its a much louder in person than the video. The power increase is a big difference.

why did you say fed ex bought them?

[SS-Power]

why did you say fed ex bought them?

It says "brought" not "bought"

[Johns00Z28]

Sounds good! Did you reuse the stock header bolts?

[cruzc5frc]
