The stick is 12556460 and the tube is 12562853. You should be able to go to any GM parts store and they will order it for you so you don't have to pay shipping

Subject: Re: Write-Up: Installing SLP Exhaust Headers Thu Sep 13, 2007 9:16 pm

yup. I got it from Ed anyway because it was less with shipping than buying it new at the dealership. Here in canada, dealer cost is approximately what you guys pay for list!

Also, Aaron's write-up makes the install look deceivingly simple. Dislodging the bolts is a challenge in itself...

u guys are shaking my confidence happy

My car had over 100k miles when I did the job. It's a days work, pretty straightforward. Have your welds done at a shop. The rockers took me longer to install and involved more risk.

heres my install, a little different.

1. i used EGR block of plates and totally removed the EGR. I have some actual room back there now. heres the header plated off

and the intake blocked off

2. the new o2 sensor harness would fit my riv, so we used the extension and pulled the connector from the new harness and pushed them into the original connector.

couples extras: for the life of us, we could not disconnect the stock crossover peice from the read exhaust manifold. we had to cut it with a saw, so the stock exhaust (minus the front manifold) is worthless. the rear manifold isnt shown here

and installed:

entire thing only took about 8-10 hours depending on if you count a couple breaks. rockers were much harder. I didnt get photos of it, but I got the straight pipe in place of the old cat. the welds are ok, but there is an obvious leak so i will be going to the shop for touch up welds.

ran the car around the neighborhood, its running lean but I dont know if the exhaust leak causes that, if I need to tune, if there is a vac leak (intake block off plate may leak), or if the PCM just need to learn.

Update: drove it a little yesterday and the fuel trims are rich until it warms up. They they bounce from 16.4 down to 4 back up to 16.4. Weird?

new update: got the massive exhaust leak fixed where the straight pipe connected to the stock cat back system. Its alot quieter now, but the headers did give the engine more grumble. I can hear that annoying ticking AA talked about now. Fuel trims only got to +11 so I think the leak fix helped.

Subject: i did a search Wed Nov 05, 2008 4:47 pm

and didnt find anything on anyone installing tog's, i have the cash to buy some headers so i was leaning towards letting out some more air out

Subject: Re: Write-Up: Installing SLP Exhaust Headers Wed Nov 05, 2008 6:37 pm

what the heck, why does this go with the SLP thread....cant i just have my own thread?????

Subject: Re: Write-Up: Installing SLP Exhaust Headers Wed Nov 05, 2008 6:37 pm

i mean i specifially said TOG's.......dont mean to seem like an *** here but ive had my posts combind with too many threads

Subject: Re: Write-Up: Installing SLP Exhaust Headers Wed Nov 05, 2008 6:42 pm

togs, slp, zzp knock off's, headers are pretty much the same. installing them should go just like in this write-up. no need to have a separate thread for each manufacture of the same part.
if you install togs on a series 1 motor, you can have your own thread happy

That's because we like AA to keep all related information in one place so we can find it. A header install is pretty much a header install. They have their minor differences.

One of the things I've grown to like about this board is that there aren't hundreds of two-post threads asking the same questions over and over. That is rampant on other boards. At least your post wasn't deleted!!

Subject: Re: Write-Up: Installing SLP Exhaust Headers Wed Nov 05, 2008 9:52 pm

What are the primaries on the TOGs you are looking at? IIRC there are TOGs and TOG Extremes. The Extremes have a larger primary which is really a track-only engine build kind of header.

im surprised...and seriously, thanks for the info

Subject: Header Compatibility Thu Dec 18, 2008 11:37 am

I have read that GTP headers will indeed fit onto a 98' Rivy, but I guess what my question really is, is the performane level. Will they fit on with little, or no issues or modifications? Will they perform well, or at least comparable to aftermarket headers? I have just received a free pair from a friend, and am just curious if it is even an option to use them! Any info would be great. Thanks........

Do you mean GTP exhaust manifolds? If they are true headers, they're aftermarket. GTP uses same engine and exhaust manifolds as the Riv. See installation of GTP headers on a '98 Riviera earlier in this thread.

Well clearly this guy that I was talking to, did not know what he was talking about. So your saying that they are stock with manifolds instead of headers. I'm not familiar with the Pontiacs, but he said otherwise... Guess I'll start a header fund ! lol Thanks

Subject: Re: Write-Up: Installing SLP Exhaust Headers Thu Dec 18, 2008 2:01 pm

I have not seen them just yet, or I guess that I would have known better. bummer... pale

Subject: Re: Write-Up: Installing SLP Exhaust Headers Thu Dec 18, 2008 2:24 pm

On the Series II, it's not a buick/pontiac/oldsmobile difference. It's all the same engine.

Subject: Re: Write-Up: Installing SLP Exhaust Headers Thu Dec 18, 2008 2:44 pm

Thanks guys, new to the V6, have only worked on Chevy / GM trucks for Quite some time, so please excuse my ignorance on such matters. My wife has a V6 Mitsu, but I have not done anything to it in the 3 1/2 years that we have owned it. Looking at it, I'm not sure if I want to either, damn nippon crap....lol

Subject: Re: Write-Up: Installing SLP Exhaust Headers Sat Dec 20, 2008 2:04 pm

Oh wow, all this time I thought we needed "special" headers for our rivs because of the bends and routing of our headers, I never knew that the GTP and riv and all other series II 3800 supercharged engine headers were identical. I guess because when I was looking them up last summer I saw listings for the GTP and SSEI's and it always said call company about Riviera's so I thought they had to be special ordered or something, lol. I still dont have the cash right now to afford them though, hopefully by this summer I'll beable to.
