Custom Fab Titanium Exhaust

[misfitsfreak81]

Hello all zilvians. Im gaugeing interest in a project that Im planning in the very near future. My plan is to fab up a titanium exhaust for s14's with SR motors. We all know that Ti exhausts for the like of Greddy or Tanabe are very very expensive. My goal is to create a compareable product at significantly less expense. These will all be custom made and Tig welded by hand.

Currently Im in the process of sourcing the Ti Tubing. I should have an approximate price within the next couple days. Once I have the first exhaust completed I will post pics. Please feel free to PM or post here if you are interested.

Thanks for looking.

+1! don't forget about s13 owners!

The problem with any Ti exhaust is that it's impossible to bend correctly. You have to make pie-cuts for everything... time consuming, and not good for flow if you take short cuts. Looks rad when done right

Another problem is that you'll have to laser-cut the flanges, gets costly real quick when it takes 4x 4x 1/4"+ just to make one flange.

I'm interested to see what you come up with for pricing and design.

I will try to get s13 figured out as well, its just that I have my s14 to do mock ups on so its easier. Im not sure how close the routing of the exhaust is between the different models. If someone local wanted to drop off their car I could work something out. thanks

Yeahhh... Was going to offer an s13 for mock, but that's a little too far.

Sorry

Titanium bends nicely, it just requires much more force than aluminum for the same wall thickness/diameter.


I'd possibly be interested in an S13 piece depending on pricing.

[Epic720]

interested pending prices for s13 and s14.

[xs240]

+1 on s13 and what GSXRJJordan said... If you can do it... alrighttttt!

I've never seen a titanium exhaust be bent - not in motorcycle racing, or ultra-high-dollar automobile racing. They're all pie cut.

The only titanium I've seen bent is like super small diameter tubing lol.

You should make a Titanium trust DD exhaust for the S14. I would definitely buy one of those!

[usdm180sx]

Make it FLUSH for good ground clearance!

dooooooooooo itttttttttttt

Everything these people said. Flush trust style in titanium. What more could you ask for in an exhaust? Oh, yeah and s13 love.

[chuy]

As another S-14 owner, I'm after one that is tucked under the car as much as possible and one that is like the DD. I'm running a KA-T with SR down pipe and test pipe, hopeing that your design will bolt right on?

[S-Nation S13]

s13 im looking into swapping out my greddy ti is this application going to have a silencer?? lol i ask cause i live in oceanside ca land of wack a** tickets

JIC,Trust, and Fujitsubo all use mandrel bending for their Ti exhuast today.

More of smaller priviate shops still do the pie-cuts. And since no-one really makes large bore Ti piping most just start with a big flat sheet, roll it to their desired dia' and start from their.

Here's a few i've had,

Mandrel:


Pie-cut


Back to the topic, I'd be very interested to see what you come up with, having tried several Ti-setup's out their It would be great to get something local. I personally would love to get a Quiet Ti exhuast. Somthing with a oval can, just different from the run of the mill like i had before.

Keep us posted.

[S13SILVIA|E46M3]

You are actually able to bend Ti quite well, just no tight bends. Here's an example of my late M3s exhaust...

Goes into a couple of nice bends, then the rest are pie cuts...

And please make sure to get those mounts right....

Pic of Ti Mid-pipe on M3. Ti is strong but brittle. Mounts were a little off and Ti just CRACKED under the stress and heat. Sucked

[GSXRJJordan]

^^^ Wow, sick guys! I guess I've just never seen it, because all the stuff I've seen has been one-off. Cool ~ makes sense that Paul would have multiple examples... ballllllinnnnnnnn lol.

This thread is full of win already.

[Brian]

how thin will the pipe be?

From what I have seen, the titanium exhausts are SUPER thin and are not very durable.

With these low cars that scrape everyday, it wont last long.

[ManoNegra]

what price point are you shooting for?
from experience Ti is very expensive
and probably will fall off the reach of most 240 owners wallet

and while we're daydreaming, why not inconel?

[xs240]

What are some benefits of inconel?

[misfitsfreak81]

wow!! Never thought i would have this much interest all ready. Zilvia.net Rocks! I will try to address all replies in order. here it goes.

95KA-Turbo, yes it will be similar to the Trust DD style.

usdm180sx, it will be as flush and tucked up as possible while keeping the straightest flow path possible.

chuy, yes it will bolt right on to a stock location downpipe.

S-NationS13, planning on using a bolt-on ApexI or similar Ti Muffler section. you should be able to source a silencer for it pretty easily.

Paul2x, i dont have a mandrel bender yet, so the first ones would be pie-cut. if enough people are interested to warrent me getting a bender, than i for sure will do it. i have never seen an oval titanium muffler canister, but that doesnt mean they arent out there. you could always bolt a stainless one up to the end of the ti pipe.

S13SilviaE46M3, yeah ti can be brittle. the mounts will be different than the ones in your picture.

Brian, piping will be pretty thin, not exactly sure on the size just yet though. im waiting to hear back from my suppliers. it will be fabbed to all but garantee no scraping. thats always the final consumers choice though on how low they want to run their cars.

ManoNegra, not sure on prices yet. hopefully not out of the price range though of everyone on this site. shooting for an affordable, quality, titanium exhaust.
No Inconel. there really is no benefit to it being used in this application.

To all the S13 guys and gals out there, have patience. I have a friend local to me who im sure will let me use his S13 hatch to fab something up.

Once again everyone, thank you for all the interest. I will have prices up within the week hopefully.

make sure when you make the exhaust, you make the canister adjustable, some of us run kits and we dont want the exhaust being sunk, i like to have my exh sticking out like 3in past my back bumper.

Excellent point. I will certainly do my best to make the adjustable in some way for different body kits. thanks for the thought, im not currently running a kit so that may have been something I overlooked.

Adjustibility is going to be very difficult. It would be nice, but I can't think of any way to do it without having to mod the exhaust (add flanges and include interchangeable straight pieces behind the tips)... which is inefficient/costly.

same as Ti but better, ie strenght, light, great heat characteristics
what F1 uses nowadays
also $$$$$$
wasn't meant to be taken seriously btw...
