Turbo-Back Downpipe

The Downpipe

Kraken downpipes run from the turbocharger back to the exhaust on the Miata. Each one is 3", in 304L stainless steel, TIG welded with pie-cut bends. The turbo end matches your turbo's outlet flange. The cat end is built for your car: the right catalytic-converter length and flange for the chassis, or a 3" V-band for a custom or aftermarket exhaust. They fit the NA, NB, and the NC in its stock exhaust location.

Downpipe Questions

Which downpipe do I need?+

Choose by your manifold type, turbo type and chassis. The manifold and turbo set the inlet; the chassis sets the cat flange and length: NA6 370mm, NA8 440mm, NB1 (and US NB2), NBFL (and US MSM), or the stock location for the NC. Custom or aftermarket builds end in a 3" V-band.

How does it connect to the turbo?+

By a V-band at the turbo. GT 5-Bolt turbos include a cast V-band adaptor elbow; G-Series, EFR and twin-scroll EFR turbos connect by a V-band flange, with no elbow.

What diameter is it?+

A 3" pipe. The cat flange is 3" or 2.5", matched to your car's cat.

What is the 3" V-band option for?+

A custom or aftermarket exhaust, or a Kraken, BOFI or FAB9 V-band downpipe. It ships with a complete V-band set.

Does it include a catalytic converter?+

It depends on the option. The NBFL and US MSM option is a one-piece downpipe and midpipe, effectively a cat-back. The others are built for the car's cat location.

Which turbos does it fit?+

It is matched to the turbo's outlet flange and fits numerous turbos, including GT 5-Bolt, G-Series and BorgWarner EFR.

What is it made from?+

304L stainless steel, TIG welded with pie-cut bends and a braided stainless flex joint.
