Exhaust model to test fit TD system

[captainofiron]

So while my car has been down waiting for opti to get rebuilt, I continued considering my exhaust.

I havent been happy with it for a while, so I was going to rebuilt the Y, and call it a day, but one of my coworkers (builds dirt track cars) said he would fab up a true dual system for me.

Anyways, being an engineer, I got under there and took tons of measurements, both from the car and the existing exhaust. I then got on ProE and built a solid model to see what bends and pipe lengths I would need, and also to test fit everything, so we can mock it up faster.

So I finally finished up.
The system is basically a clone of the Kooks 3" system, BUT I used 2.5" pipe and the mufflers are sweet thunders 18" long, and of course my FLP headers use a Vband flange.

Here are the results

NERD.



Just kidding. I like that. A local guy is running a similar setup with bullets instead of Chambered mufflers. Sounds really tame actually. Im surprised at how smooth it sounds.

haha, well nerd/geek a little of both, haha

anyways, when I was starting to think about ordering stuff, I did NOT want to order way more than what I needed, the guy took some measurements and wrote down the bends I would need and his estimate of material costs was nearly 800 bucks for mandrel bent 2.5" 304 Stainless steel pipe

with my test fit, I was able to nail down the routing/bends/lengths needed, and the total cost is going to be below 500, depending on whether or not the piping supplier gives me a break on the shipping.

And as for the muffler, I picked the chambered because I thought the bullets were too quiet also

I WANT!!!!!!!!

I WANT!!!!!!!!

Thanks.

When I get this thing built, I will post some pictures as well as weld diagrams and parts list so anybody who wants a TD system like this can build it up.

Looks like the one I built a few years ago. Only at the rear I have a single magnaflow dual in/dual out muffler and 2OTL tips :)

It should sound badass, and BTW great design skills. I just get under the car with an idea in my head and go to work and make it fit. Your way would make things a little easier and with less screw ups haha

That would be awesome man I've wanted to get on this for a while but just had too many priorities pending

cool man, post some pics up.

thanks, well I would have just gone under there and started working too, but now that Im married I cant let the cash fly so easily on my car, luckily my wife is cool with me wrenching and modding, as long as I pay the bills first haha

Yea I was in the same boat. hopefully this weekend I can get the TA going 100% to take it to my friends house and we will fab it up.

I will post up an exact template so that anybody can copy it.
I just want to get it in there before I post it just in case i modeled something wrong

Mine doesn't look amazing by any means, but for being the first exhaust I built I'm pretty proud of it. And it fit with no rubbing :)

I hear you on the married thing too, but my wife lets me spend some of her money on my car :D This winter I tackled the complete suspension, I have a thread in the suspension section. But I still get yelled at for spending more time with my car than I do her haha

Heres the pics of mine, it looks like it hangs down in the last pic, but its about 1/2" away from the rear seat pan

Done with the thread jack now :

[captainofiron]

man that does look like it hangs low, it doesnt scrape?

Im going to mod the rear seat pan, ala-BFH mod so I dont have that clearance problem

[captainofiron]

ok so I got under the car yesterday and took more measurements and refined my design.

I had made a few assumptions, and a few were good, and a few were bad.

So here is the revised model,

I will post up portions of the model so someone can hopefully turn my drawings/model into an actual system.
