Any thoughts?
I'm not getting the AMS downpipes so I can use the extra $ towards other things.

We use the same supplier, though use Stainless Steel Flanges at the Downpipe to Midpipe connection.

We charge $600 shipped via Fedex Ground, but will be happy to price match any offer you can find for a cast downpipe.

SBD so easy to talk to him, he's here.

Have you considered Linney/GTC???

I'm trying to get the closest to the AMS downpipes with their casting, but not the AMS price.

The world record on stock turbos was done using our 3" Cast Catless Downpipes, so they are more than capable

Does SFS make cast flanged downpipes?

SBD and Rexpeed cast DPs are the same thing.

SBD and Rexpeed cast DPs are the same thing.

Same parent supplier, but I don't believe Rexpeed uses Stainless Steel Flanges at the Downpipe/Midpipe connection.

Again, someone would have to confirm their makeup with them, as I specifically requested this upgrade for our production runs.

I've never seen their downpipes in person, so I couldn't tell you what materials they elected to use for their production.

Edit: Spelling

And hows the drone and heat with cast downpipes like the AMS or SBD's? should you get them ceramic coated and or heat wrapped?
GT-R interior gets warm already on OEM dps.

 

[spdbydesignChris]

The beauty of Catless downpipes is they don't retain heat like your OEM Catted downpipes.

I see no need to ceramic coat or heat wrap.

In over 300 sets sold, I've not once had that complaint from a customer.

Does being 90mm make a difference? At the FBO level.

Not really, but you are set for success if you go further later on

Where are the studies showing any power Gaines from a cast vs stainless pipe Jw if any one ever showed testing to compare....

Go with the AMS, much higher resale should you decide to sell them and they are the best in the market. Can always buy used as well.

Good luck.

gtc or cobb both have cast and would be closest without paying for ams

Can anyone here tell me what 3" dual piping will support HP wise?

I'll give you a hint, more HP than ANY factory manifold turbo setup can produce.
