I'd have to get rid of my catalytic converters though, wouldn't I?

So let me try and get this straight...

...you run two pipes into one turbo inlet, and then piping from there down, and then I could split the exhaust there, into my two mufflers?

Or would I be best just running single exhuast?

 

What happened to your left eye?

 

All modern turbo gas cars still have cats. You will have to keep them to pass emission, if required.

Based on no experience...just a mechanical engineering degree, I'd approach it like this -

I would make the manifolds and "up-pipes" as absolutely symmetrical as possible. If one has to be longer and one shorter, make them both longer. Bring them together into a symmetrical, restriction free Y-joint, and feed it into the turbo.

Then onto the cats...you'd probably be fine reusing the stockers. Can anyone chime in on whether damage arise in the tuning process, or due to poor tuning? Maybe a pair of quality high-flow cats?

After the cats, pretty much whatever you want...probably with as little restriction is possible.

I gotta say, for an application like this, I would go remote mount all the way. But it's your truck. It would be something to see for sure.

I'd bet you will pay several hundo per manifold. And someone who really knows what they are doing better lay them out. I would not start a project like this without a CAD model...too much to go wrong without a ******* fitup! I'm no Jesse James. 3D CAD can do excellent piping layouts, and even break it up into individual pieces after you've got it laid out.

**Edit** And yeah...$20,000? Left eye?

 

v-i-r-t-u-a-l is a censored word? what?

 

I got hit in the face with a golf club when I was 6 years old...

 

As for the catalytics...

Since I'm gonna be only running one pipe from the turbo back, can I just use one cat?

 

I would think a single cat might not give the exhaust enough transit time and surface area to effectively remove all unburned hydrocarbons. Maybe a single large, high flow, high performance cat would do the job. But it might be trial-and-error when you get inspected.

 

Ouch!!

 

I have no inspections

 

I doubt you're going to be able to fit a turbo above the engine, a turbo is a lot bigger around than a blower is tall.
