Weavsvet	TPIS vs Stainless Works LT's	#1
Senior Guru 446 Posts Member since: 2008/9/16 9:08	Started changing out these headers this morning. Going to TPIS 1 3/4" from Stainless Works 1 5/8" with the AFR 195 St. Elim. heads. Below is a link to show the comparison between the two using the Fel-Pro 1404 gasket. Which btw fits the AFR's exhaust ports perfectly. The SW were blocking the exhaust port considerably IMO. You can tell by the soot on the SW header flange. The TPIS didn't fit the 1404 perfect either. They do now though. Just a very slight porting of their round exhaust ports took care of the fit. I feel this this will help exhaust flow quite a bit. http://s274.photobucket.com/albums/jj ... s%20Works%20LT%20headers/ EDIT: Had the Felpro number wrong but it is fixed now. I had 1204 and it's 1404.

The pictures do not really show the difference in these port sizes and how much was being blocked with the SW. This does though. Good idea Steve! SW header ID 6.01mm avg.(yes I doubled checked this). TPIS ID 15.88mm avg. Fel-Pro 1404 gasket ID 13.80mm avg.

Do you guys think they were made this way so they could be cut off if needed? The cats are right next to the transmission. I really don't think I have a choice just want to ask.

Elite Guru 1114 Posts Member since: 2005/12/20 0:00	I would cut it and make it work.. The headers arent needing the extra length for any other purpose than fitment to wide range of vettes in the C4 line. Cut it, put some band clamps on it, and ensure your cats arent touching the floor boards or the tranny.

I'll just have to get some heat shield tape or something to protect the undercarriage next to these cats. Might also have to fab up something for the tranny to shield it. Those Walker clamps appear to have sealed really well. At least this way I can disconnect the headers form the exhaust system if need be.

Elite Guru 1114 Posts Member since: 2005/12/20 0:00	Just curious, if you would have cut more off, like 4-6 inches so the cats are right up to the collector, would they clear the transmission and body better?

Maybe but I would have had to cut the cat to. That would have put me into a big mess at the other end. The pipe would have to to short. If it doesn't work out I'll get some stainless and move them up. I looked at some old pictures with the SW on there. The cats are in about the same spot these are just bigger in dia.

What can I put inside the clamp to help seal it off? Will high temp RTV last? How about "The Right Stuff"? Would it hold?

Senior Guru 446 Posts Member since: 2008/9/16 9:08	Damn it!!!!!!!!!!!!!!! I fired it up this morning and let it run for a while. So why I'm fiddling around doing something else I look up and there is black smoke poring up from the back of the engine! Smells like plastic. I run get the water hose and start spraying. It didn't seem to help any so I look under the car and the right cat is glowing bright red. I guess it was melting the under carriage. The left side was fine. I'll have to look later today to see what the damage is. What could cause a brand new cat to do that? Acts like it's plugged or something.

For the right side to be lean, you may have a broken spark plug (header install can cause this #8 on TPIS), or a loose/broken wire on the O2 sensor, or loose sensor in the bung, and of course header leaks at exhaust gasket. There are some other things, but you dont touch them for header install.

Senior Guru 446 Posts Member since: 2008/9/16 9:08	One of things that had my attention when all of this happened was I was looking at readings on the Tech1. BLMs were 128/128. I'll have to check it for a leak at the band clamp before the cat on that side. But seems like BLMs would be off if there was a leak. Injector v on all 8 was 4.2 something @ 1000 rpm. I'll just start checking things. It's possible I may have switched the 02's from one side to the other because I didn't mark them. Yes, #8 is more of a pain with these headers even from underneath. I'll check that also. Thanks!

If both sides show blms 128/128 and voltages good we need to look at mechanical, ie plugs etc. burnt/or arcing plug wire close to header..

Senior Guru 446 Posts Member since: 2008/9/16 9:08	Ok, I've made sure there are no exhaust leaks, checked plug wires(number 6 slipped on a little but no much). So it's sitting there idling and I keep looking under the car at that right side cat. After about 15 minutes that sucker is glowing bright red again. The voltage on the right side 02 is fixed at 43mv or so. The other side is bouncing around all over the place. I changed that 02 out with another one I had and it's the same fixed mv and not moving. Do you think this is a wiring issue? Wires look ok around the 02 itself.

I really expected to see a big hole in there. As usual another self inflicted wound on my art. I had #2 & #4 plug wires crossed. The problem now is that the left side cat is glowing after running a while now! Just have to start checking that side after it cools down some. I may have a exhaust leak on that AIR connector where it screws into the header. BLMs are 130 on that side now. I hope it's that simple.

Ultra Copper RTV that pipe thread going in there. Now hopefully the other side cat is okay. Did that. Solomon says those are LT fuel trim numbers and 130 is close enough. I hope the cats are ok too. Right (edit, right not left)) one got really hot. twice!

Any extensions have to be added upstream of the plug. An O2 sensor has to have ambient air as a reference. Believe it or not, it gets it from the wires. putting a splice in there screws it up. You will need a new O2. Eddie Quote: Weavsvet wrote: It's down off the stands but I'm still getting a low voltage code on bank 1 02 sensor.

Eddie I think the lean condition is correct, as far as the ECM sees, and therefore it dumps fuel to fix the lean condition

Its in the FSM. It will ruin the readings, which is from 0- .1 volts, not much room for error.

Being the "not paying attention" individual I am I had crossed #2 & #4 plug wires. That is what was causing bank 2 to fire up the cat like it did. The jumper is a 12" plug and play jumper that came with the headers. Probably for the rear cats (which I don't have). I'll just remove it and try to get the 02 wire off the header and see if that takes care of it.

Senior Guru 446 Posts Member since: 2008/9/16 9:08	This is getting old really fast............ So, I replace the bank 1 02,take out the jumper and go for a 30 min drive. It had thrown a code in shorter time than this last drive. I almost make it home and BANG! SES light,crap! I check it out and it is different this time PO1153, slow response bank 2 sensor one. I wrapped the 02 wires up in reflective heat tape. Was this a no no? That's the only thing I did different on that side. I'll remove it after it cools down and try again. Another thing according to FSM is the use of some RTV. I used high temp RTV yesterday to seal off the band clamps. Wouldn't it have thrown this code yesterday instead of waiting until today to do it if it was the RTV causing the code? Mercy...........

The O2 sensors can not be altered or have any rtv at all on the threads etc. They come with something already on them. I would check wiring on O2's. Ensure they are not cut at all from connector to O2. Are you sure the tune has the O2's after the cat tuned out?
