Nice work
I bet you are enjoying doing that tig work. I do myself. Your work looks super.

It was much more difficult to get the torch in at the correct angle on those and I had a hard time positioning the piece while welding. But in the end all the pipes are fully sealed and that's what really matters.

I also got the merge pyramids welded in place. These seal off the center section of the pipes so there are no leaks and provide a smooth transition for the exhaust gas to go from individual pipes into a single larger pipe.

Finished welding up the headers today. Man it feels great to have accomplished that. I am very pleased with the way they turned out. I am also glad I designed them in CAD first. They fit exactly like the CAD model predicts.

For those interested here is a picture showing a full penetration weld of a primary tube to the thick flange where I used the Solar Flux instead of back purging. I chipped away half of the glass like coating left behind so you can see underneath. It does a great job, no oxidation.

After I was finished, there was some slight warping on the header flange so I leveled it by placing adhesive backed sandpaper on the top of my cast iron table saw (which is ground very flat). By running the flange back and forth a few hundred times, I'm not kidding either, the flanges are now dead flat.

I needed to make a handy jig to hold the assembly vertically so I could weld on the collectors. Notice the back purge setup for these welds.

Here are some more pictures of the finished product.

Next I will be adding in the resonators and tail pipes. I bought these shiny ones, aren't they pretty :p

Your headers turned out very nice! You have hidden skills. I wish my first weld job looked that nice!
Sharp
beautiful
Outstanding work!
Great job John, your decision to mod the frame rather than moving the engine back an inch really makes this routing of the headers much easier. My dicision to move the engine back may prove to be problematic. I also only raised the engine 1/2" I'll probably raise it another 1/2" to an inch like you did.
Modifying the frame was definitely a good choice. It has made many of my other modification easier.Quote:

Your work makes me feel good just looking at it.
Heck, I couldn't weld like that a month ago. All it takes is determination and practice.Quote:

Beautiful, can’t wait to hear it.
Nice work On the 33 there is very little room! It is fun to build your own parts, welder, grinder, time = new one-off parts!
Finished the exhaust out the back finally. I made some neat exhaust hangers that incorporate into the u-bolt clamps to hold up the back of the mufflers. I wanted some type of mounting that would have some give and flex when the motor vibrates and twists. The nice part is the hangers are threaded at the top so I can adjust the muffler height very precisely.

I had to relocate my wing mount uprights and my transmission pump and my oil catch can, but it was worth it!

Two thumbs up now lets hear a sound clip.
Was thinking bungee cords. Yours is nicer. Looking good!
Ooh.. it sounds nice.
I'll post a short clip after I get the idle working.
beautiful work. Clever design.
Here is a short clip with the new headers. My phone camera gives the exhaust a raspy sound that you do not detect when standing near it.

Sounds great and very unexpected with the idle tone!
Very cool!!
wow!!!
Getting close to being finished with the winter modifications this year. One of the last things on my list was to make a cold air intake that rams cool ambient air into the intake from the passenger side vent. I ended up going with an inline air box (its a cylinder really) that has a cone filter inside.
https://thefactoryfiveforum.com/atta...4&d=1553375734
I started by bending up a square tube the size of my intake adapter ~ 4 1/2" out of some scrap aluminum sheet. Then I needed to sculpt it to fit the side sail as best I could. That was quite hard, trying to fit a square tube to the multi curved inside body. I had to angle it up enough to clear the inner fender but not so much that it interfered with the rear deck lid. It was a very close fit.

I then used resin and mat to bond the aluminum scoop to the inner fender in three places.
Attachment 104227 Attachment 104228
After the resin hardened I reassembled the body and checked for fitment. I love the way it came out and it should give the engine plenty of cool air, especially at speed!

Very nice work!
Back in a previous post, I opened up the gap between the leading edge of the doors and the back of the front fenders to allow high pressure air to exit the wheel wells and get more air to flow along the body and into the rear scoops. The enlarged openings work great, but I get tons of debris and stones flying out and blasting my paint. A while back I purchased some nice aluminum hex mesh screen and now I have finally gotten around to fabricating some front wheel screens. I think they are a nice touch and will hopefully prolong my paint job.

John, you can also add some Helicopter Blade Tape to the leading edge of the door. (tough stuff looks like a clear bra) let me know if you would like some, I can send it over.
Thanks Mitch. I actually have XPel clear paint protection on the leading edge already. It works well but the added protection of the mesh is good for the large / sharp stones.Quote:

I decided to try thermal wrap on my new stainless steel headers. I figured since they shouldn't rust the wrap should be ok instead of the very pricey ceramic coating I used on my first set of mild steel headers. Some tips for others planning to wrap their exhaust.
- Use the expensive wrap from DEI. There is a reason they are the best.
- Get the Titanium Lava Rock wrap. It doesn't itch and its very pliable without having to wet it.
- Use safety wire to tie off the wrap. It's easier and you can get it tighter than those dam straps they give you.

From a purely aesthetic non functional stand point those fender openings look awesome. I would do that to my car even if they served no purpose. Headers look good too.

A friend had enough oil related fires that he went to Heatshield products. Available through Summit. Though pricey, they last a long time. There are several other brands with similar products.
I've used the Heatshield Products stuff as well. It's pretty awesome for heat retention. It can be removed and reinstalled easily. However, it still a fiberglass mat type material on the inside and soaks up fluids.Quote:
