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

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

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.

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

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.
