JIC Titanium exhaust

[eyesoreracing]

Ok, here's the long story:

So I've got this car:

And it had this bitchin 14-lb titanium JIC exhaust:

Everything was great, until the super-thin flange at the front of the exhaust cracked. Lucky for me, I had a friend who could weld titanium, and he happened to have a new, much thicker flange sitting on his desk. Wham, bam, thank-you Culver!

But we were stupid and didn't jig things up precisely enough before welding. The exhaust ended up very slightly off center. It didn't hit anything, but it kinda melted the bumper a little.

Ok, there was an enormous cone of flame shooting out the exhaust before it caught the bumper on fire, so it's not all because of the cock-assed flange.

So, when I put the new bumper on, I made this framus that pulled sideways on one of the hangers, yanking things back into place.

That was dumb.

The stress on the exhaust from effectively being bent sideways eventually overloaded some welds inside the resonator. The perforated core is now loose and rattling around inside the exhaust. There are no leaks, and the sound level is still quite reasonable if you have a cat, but it rattles at idle. Very annoying.

So to make this thing really work well, you need to find a guy who can weld titanium (I can recommend a guy if you're in Orange County) cut it open at the ends of the resonator, either weld the core back in or simply take it out, and then weld it back together. Remember to tack weld it while the exhaust is mounted in the car, otherwise you'll end up with it a misaligned exhaust again.

So why don't I just do that? Problem is, I run the car at Laguna Seca all the time, and they have this rediculous 92dB sound limit going up the hill between turns 5 and 6. Even stock EVOs have a hard time passing sound there, so I had to remove my 14lb rust-free titanium system and replace it with a 35lb steel exhaust that's going to rust out in a couple of years. All because a bunch of rich fucks moved next to a legendary race track and then decided they didn't like the sound.

So, back to the exhaust. It's not a show piece, as you've probably gathered. It's scratched, it has a small dent or two, and it rattles. Fix the rattle and hang it properly and it should never have another problem. The system is very intelligently designed, with hangers that weld to clamps wrapped around the exhaust, so the welds won't fatigue and rip the pipe open, and a slip-joint holding the muffler on, which also reduces stress. And, except for the rattle, it sounds really good.

Here's a little dent:

Here are the brilliant, hollow exhaust hangers and the clamp they attach to:

Here is the very nice slip-joint at the muffler (newer JICs have a flange here, which is more likely to crack. This is a very low-stress joint, which is why you see it on race exhausts.)

And here's my twiggy, 110-lb girlfriend holding the entire system with one hand:

So, $450 including ground shipping in the U.S. (it's light, so that's easy...)

I am trying to figure out how it burnt your bumper so badly. Thats crazy!!

[s13pignose]

Is that the sport compact car mag project s13. If so I remember reading thej issue where they said the bumper caught on fire, and they welded a plate on the bumper cut out as pictured

[soon2bRB240]

I wish it was for an s14! Best import mag out there hands down btw.

[Syncade]

its a shame SCC has gotten so thin. Everytime i read Super Street, i forget that I dont own a honda. Even Modified Mag is annoying with the new editor.

Every mag is so omgz0rz dr1ft! now it makes me sick

Nice pipe:)

[an_orange_s2k]

damn the damage to the bumper is crazy otherwise nice exhaust!

[eyesoreracing]

Yes, it's SCC's old project car.
Yes, SCC rocks.
The bumper burned because an intercooler hose blew off, causing the ECU to dump tons of fuel into the engine, which then blew out the back in a giant ball of fire. Barely made it to the fire extinguisher in time. If www.sportcompactcarweb.com didn't suck so much, I'd put a link to the story here, but it does suck, so I can't find it.
Yes, it's a nice pipe, so buy it!

[eyesoreracing]

Bumpin it 'cause I lowered the price.

All of those mags are horrible now. The only mag I look forward to reading anymore is DSport. Good Tech , Nice Cars , less bs.

[khoadogg]

omg! are you dave coleman!?!? man, that single issue made me realize how badass the 240 was. because of that issue, my life has changed! awesome exhaust!!! and great magazine, back in 2003. when will you be back at Leguna Seca?

[SR20d2fourT]

what ^^^^^
the
hell

Hah hah! With that kind of reaction, you'd think my rep power would be higher than 0!

[Lordrandall]

Cute GF. Bump for a Dave.

[brndck]

scc sucks without coleman. jay chen is a good engineer and used to live next door to me in san luis. (i was in his kat s14 when he crashed backwards into a phone pole- oops) but somehow the rest of the mag really can't compete with pretty much every other mag on the market now. o well, bump for dope exhaust and +rep for all the excellent tech articles you've written.

[middy]

Hard to boost your rep power with just 4 posts, genius. ;) Well, at least you're good at boosting cars.

I can't find any article that mentions the infamous bumper fire, but here's the SCC Nissan project car index:

wow...this is one of the best F/S threads known to man.

any other kid would of been "yeah..JIC, super JDM, its beat up."

great exhaust though. would love to have it. (considering it.)

[middy]

bump for no good reason

[DOOK]

bump for a good looking chick holding an exhaust like she owns it...

[a_ahmed]

as soon as i saw the car i knew which car it was, that car was pulling consistent 1G corners with whiteline swaybars and jic flt-2 coilovers with lighter springs, due to very bony skinny tires though so it all works great, and the hlsd too :)

[carbotron]

what's the piping diameter on this? and are the guts of the resonator Ti as well? and what's the resonator stuffing? jsut
it is for sure the resonator not the muffler that's rattling, eh?

if the magic dave says "signs points to score", i'm going to try and jam it onto my s14 ls6 project.

if not i suggest someone with an S13 jsut whacks off that flange with a sawzall and runs those long SS band clamps: http://www.jegs.com/p/JEGS/753274/10002/-1

[UfoZ8myCow]

How much did Culver charge you to weld that flange on? $900? I assume you're talking about Culver from GT Fabrications, right?

The muffler is separated from the exhaust now (to fit in a box) and the resonator is the one that rattles.

The piping diameter is some metric equivalent to 3". Its plenty big enough.

WTF?

Yea, that would probably do it too.
Cutting titanium is cool. The sparks are white.

Yup, he's the one...

It's not that expensive to weld titanium. I mean, if you're doing aerospace quality welds on an SR71, sure, it's hard, but just gluing together some exhaust parts is pretty simple.

Ok, the exhaust is on eBay now, http://tinyurl.com/5jrtea. If you've been holding out for a lower price, it might happen there...
