This is not a genuine MODE set. Buyer beware. By the way...it's Holcombe!

Interesting design.

Looks like made for a split turbine w proper wast gate design for such, nice collectors, low volume for fast spool, but not quite equal length.

Thumbs up

Actually, these are a really old set of MODE headers made for Roger at Orbit Racing back in the day. I stand corrected.

They also look like you could enlarge the exhaust ports in the cylinder head a little if you wanted to.
Nice looking headers. I occasionally like heat in the winter though.. mostly at night even in S. Florida.

Orbit Racing is local to me.

What size snail bolts up to those things? That turbine inlet flange looks HUGE.

Looking like a T4. Easier to find Split Scroll turbos in and flows more.
