ok I was browsing and I came across this set of headers and they are cheap too. Here is the link http://www.wbodystore.com/grandprix/...roducts_id=118

please tell me if they would fit my 02 sle TIA

applications:
1997-Current Grand Prix w/ 3800 Engine
1997-2003 Regal w/ 3800 Engine
2000-Current Impala w/ 3800 Engine
2000-Current Monte Carlo w/ 3800 Engine
1997-2005 Bonneville w/ 3800 Engine

yes

dbk2 picked some up for his GP GT

OK....here is the straight poop.

So far, nobody that I know of has tried the Pacesetter headers on a Bonneville. Despite the w-body'* store listing the Bonnie as a current application, Pacesetter'* own site does not.

LIke with any headers developed for the grand prixs and other w-bodies (TOG, SLP etc.), the rear collector is pretty much dead center for those cars whereas the Bonneville rear collector is off-set more to one side. IIRC, this usually involved moving the transmission dipstick and possibly some other minor modifications to make them fit a Bonnie.

Wiht that said, Pacesetter is local to me and I have a pretty good friend that works for them. We have been talking about using my '97 SSEi as a test car (since the beginning of summer) to see about any fitment issues, but to date, I have not found the $ to buy or the time to leave my car at Pacesetters so they could do a test fit.

Whether I purchase the headers, now, or just allow Pacesetter to test fit the system I will talk to Eric again, and see if something can now be arranged to test try their product on my car.

is the 97 frame and exhaust passage the same as the 00 + bonnies

Good question. For the most part, I think they are similar enough to give us confidence that the headers would fit.

I talked with Eric, and he and I are working on a possible plan. I mentioned that the w-body store was advertising their headers for the 97-05 Bonnie'*. He said to call or e-mail the w-body store and ask them if they have had the headers in a Bonneville yet, or if they know of anybody that has put them on their Bonneville/H-body.

The 97-99 have a front mount that is different from the 00'*. With TOG and SLP installs it requires removal or modification.

I submitted a tech info about the modifications needed to install TOGs on a 95-99 Bonneville a while back. Bill was telling me it should be burried in the gearhead forum somewhere.

Thanks guys.

Which year requires removal or modification of the front mount...'97-99 or 00+?

I'll go search the gh forum to see what else I can find.

00+ do not require it.

I seached my e-mail and found it:

I installed TOG headers. They differ a little from SLP'* and even more from *&* headers. Allmachtige installed SLP'* on his car. Search for him if you’re trying to get those.
For my TOG'* there were a couple small fitment issues.
First, the front header hits the front transmission shock. It'* just a matter of cutting a 1/4" or so off the top. Here is a pic of the part that I had to cut:

Another issue was the O2 sensor bung. I had to have it plugged and moved to the other side since the O2 hit the steering rack/engine cradle. I also had to remove a small aluminum heat shield that would have been between the rear header collector and the steering rack. (Very simple, 2 10mm bolts) Here are some pics:
Plugged:

New O2 hole:

As with any header, you'll have to elongate the O2 sensor wire harness to reach too.
The last issue is that the downpipe section after the flex is a little low. I had my downpipe cut and welded higher so it wasn't as low.
