If me changing my mind and re-doing things bothers you, you may want to skip this one.

I love watching the various iterations as you come to a "final" design.

A few days work to transition things from plastic to stainless steel. A few design changes had to be made because the plastic is able to flex just enough that when things go to metal, positions change enough to cause the dimensions to need tweaking.
But it got done. I'm really happy with how this turned out.
Now to duplicate it, mirror image - which should go quicker now that I know the specs for each piece.

A couple more...

WOW !

Sexy!

That came out really nice! Run it like that!

That looks amazing Chris.

These look amazing, can't wait to hear them!

Thanks to everyone for the kind words. And sorry, @Krieger Andy, but it's getting a collector and a muffler.

Here's a mock up before each tube is final welded, trimmed to length and the collector added.

Sexy.

Pasta Power!

The Flying Spaghetti Monster would approve!



You need that on the back window.

Really impressive work on the exhaust

Is that a Burns stainless collector?

Looks great!!!!

I would like to double down on a 2.5” collector exit feeding directly to a high flow cat. That’s the one thing I would change on my 3.7L build for my 996.

@BIGKAT_83 Bob, it's from SPD, a company near me in Nor Cal. But yes, it's B-uti-FULL!

Impressive!

Superb! All those iterations must be exhausting.

Beautiful work!

A bit more progress:
- 2.25"-to-2.5" transition tacked on to collector. It'll get an O2 sensor just after the rear mount of the engine cradle
- two of the tubes final welded with the main weld seam disappeared

This is just a mock up (the collector is just set on, not tacked) to see how things are fitting after welding. I'm sure some minor tweaking will be needed ahead of being "done".

That. Is. Sexy.

It blows my mind the stuff I see Chris fabricate.

All main weld seams sanded. Hopefully, the other side will go much more quickly - this took a lot longer than I'd expected. You'd think I'd have learned by now...

Now to work out a finish. I'm considering white, as a nod to Ferrari's race cars. That or the same finish as my LS car's exhaust. That "titanium" cerakote tone would look pretty killer with the red plenum...

Just beautiful exhaust craftsmanship!

You folks are seeing progress/results ahead of the videos. But here's the latest - it covers the steps involved in getting to the past few pics. Enjoy!

I enjoy watching the process. But, you know....in the back of my mind, I am wondering if Chris is now reimagining the LS headers.......

@Cairo94507 Michael - You know me too well! On the LS car, it's not the headers. But I am likely updating the intake and the exhaust from the headers back. I have what I think is a very cool design that I'd like to try out. Watch for an update on the LS thread.

Wholly ^&*^%@!!!!!

I can't imagine how you can get into the junction of the 4 pipes to weld it all up! A tight fit. Incredible work Chris. WOW.

Hope to see it first hand this weekend if I can talk my way onto "the set". Perhaps the video production team will take the weekend off.

It's a weekend 2-fer! Here's some panel stamping and fab fun for your Saturday enjoyment:

Do you have a bead roller? it would expidite the process of adding a step to a panel.

@tazz9924 - I do have a bead roller. No way it/I could bead roll that recessed panel area. Plus, I've found the stamping approach totally eliminates any panel distortion.

To each, their own.

Figured it'd be prudent to test fit the first header. The good news is it fits as planned. The less than good news is that it's all but invisible way down there.

Clearance with the stock suspension at full droop. I'll be running shortened shocks to help limit axle angle so this area will have even more room.
O2 sensor will live just past the rear engine cradle mount.

Thats fair, distortion is a problem i typically have, usually what i do is break the edges to straighten it out, it also helps weld it on. You could also be a savage and prestress it with a english wheel but im not going to pretend like id even try it. I like your stamping for its smaller detail and not accidentally messing up the corners like the bead roller.

Maybe some LED lighting would highlight them. You’re right, those pipes are way too cool to stay in the shadows. Style points, baby!

Or maybe a few strategically placed mirrors in the engine compartment.

Very nice!

Wouldn't surprise me if your conversion header flows better than the stock Ferrari part.

Just impressive!

^ You guys are adding weight.

But don't get Chris looking at F40 engine bays with all that Kevlar lest he consider…914 Firewall 3.0

It really is a beautifully constructed item and you can see it just fine. It will be quite noticeable to anyone who cares to look. I'm very interested to see how the final exhaust system assembly will continue to differ from that of the LS motor...

Kevin

Best view of the exhaust is had by the inside of the tire!

I worked up a fixture to locate the collector so I could tack it in place

Then everything was final welded. Still have the O2 bung to add, then it's work out the rest of the exhaust.

Wowza...beautiful!

Your work is incredible. Gigantic props. Form AND function.
Is the support for the collector attached to the engine side of the motor mount
or to the chassis side ?

@rgalla9146 That's not a support. It's a temporary fixture I made to hold the collector in position so I could tack it to the primaries. The engine and headers need to move independently from the engine cradle. I'll work out muffler hangers once I get to that point.

Even your temporary supports are outstanding !
Can't wait to see the rest of the exhaust system and brackets
