Default This seasons new ABSURDflow setup for my car

In keeping with my trend of replacing my setup every year, I've started this seasons setup now that I'm done with all my customer builds. I'll be using my tried & true 9 year old 2560 at first then maybe go with the E-USA chinaturbo 2871 I got from Lars once I see how this setup feels compared to my other tubular BEGI/FM replacement mani's I've been running. I can't wait to get my car off the jackstands and give it a bath. And save gas...the subaru is killing me with these gas prices :(

This will be a forward/upper mount manifold using my traditional collector. It will work with A/C & P/S without rerouting the lower radiator hose and hopefully fit big turbos too. And it's easy to make. There seems to be lots of room but I don't have any large turbos here to check fo sho.

See attached until I upload them to my site.




More pics once I smoosh the pipes oval and weld on the head flange.

Yeah I wonder how it'll change the tone of the car. Probably not much at all

Technically I should be able to use the jig for a 1.6 version, the port spacing isn't that far off.

All I can find of splitime's manifold is a log style. But there is this mani that looks similar, yeah. I think this may be lovefab? Similarity is coincidental, and mine puts the turbo higher and further back to clear P/S stuff.

I've installed a few unequal length manifolds on some hondas and it did add quite a bit of the boxer rumble. Not exactly like a subaru, but MUCH cooler sounding than your typical equal length inline.

If it doesn't sound fantastic I will be very surprised.

he was running a 2860 with that manifold. He decided to sell it off and build a simple setup around a spare T3 he had sitting around. He then decided to swap in a VQ motor.

This.

And yah... very unique exhaust note. Full 3" from turbo back. Vibrant Muffler.

I changed to basically go back to being built around cheapness.

Ahh boy. Now I'm getting excited!!

EDIT: yeah that's similar to my exhaust; 3" magnaflow metal cat and 5x8x18" muffler. Drone at all?

What kind of drawback do unequal runner lengths have relative to the cool sound factor?

FWIW i've always noticed that bundy's car has a very unique exhaust note with his long runner equal length manifold. Completely the opposite sound of a subaru, its a very tight and perhaps a higher pitched note.

Also, the only boxer engine i've ever noticed having that exhaust note is a subaru and I was under the impression that was due to the fact that they all have unequal length manifolds unless the owner spent dollar signs converting it to equal length. Therefore I always assumed that subarus sound like they're running on 3 cylinders because they have an inefficient manifold design.

subaru's tend to gain HP when switching to equal length mani's and no loss of spool or low end. Correct, 18psi?

I did this mani so I could fit a (hopefully) large turbo and keep a/c p/s without a lower radiator hose redo and use my prototype collector cause the other manifolds I make are a PITA to build to a jig with the large blends and stuff. Cutting pipes to a certain length and/or bend and tacking them together per what solidworks tells you is turning out to be relatively drama free. If I get a suby-ish sound, great. If it's laggy compared to the previous manifold's I've run on this car with the same turbo, then I'll probably sell it. I prefer spool over sound. I am still of the general opinion (educated guess) that my traditional manifolds are more betterer than these more recent traditional collector manifolds, until actual dyno results are made. Another reason to make this mani.

I should be in the garage welding on the head flange.
