Hello there, I have a chevy Lumina SS 2001 5.7 LS1.
I don't know how many of you are familiar with this Chassis, it is the same as the holden commodore SS.
this is a picture:

I want to get some Long tube headers, probably the pacesetters. P/N: 72C2255

Do you guys know if this one fits my car? Should i order for Corvette or camaro application ? or both work ?
I am worried about the fitment.

I think that is the same as the G8.

Here are some headers for the G8.

Fitting the engine wont be a problem. It'* the engine bay that may need some work. Be prepared to move the O2 bung, or make room for the O2 sensor. I worked on a Vette a while back and with the headers in place, it was impossible to reach spark plug #1 because the IC compressor was in the way. Different body styles have a slightly different layout. Getting the headers in place may also be a problem. You may have to play around with getting them in to place. Don't be afraid to come in from the bottom. You may need to lower the subframe.

Thanks for your reply, i don;t want any headers that needs adjusting the engine bay or anything else. the o2 sensors are no problem, Weirdly enought, my car model came without 02 sensors.

For the most part, you should be OK, but I can't say for sure as I have never installed a set in the body style. But if there is one thing I have learned, when installing your first set of headers, be sure to have a lot of colorful words lined up, your going to use every last one of them.

Well i would have ordered headers for the G8 application since it is the closest to my cars look. But the G8 didnt come with LS1 engines. So i cant do that.

What about the GTO? They came with the LS1, and is basically the same car, only the coupe.. isn't it?

l76 and ls3 in the g8 should have the same head pattern as far as headers for a ls1. i think its as close as your going to get.

I think the GTO route would work...the engine bays look to be about the same size and the exact layout on the inside too....The only difference between the GTO/Monaro coupe and your Lumina SS looks to be the length of the chassis. Just something to look into...

If it'* a right hand drive car, it may not be the same fitment....
