Are those the Passenger Performance units?

 

Id say buy a tig welder and get ready for the cracks there gonna grow and shrink to hi heaven.

 

they have been tested without failure in dailydriving and competition use. the material and more importantaly the thickness of such makes it very durable and to withstand the stress and fatigue of the heat cycles. this thing outweighs my ats bigfoot i replaced it with. by a good amount. i'd have to pull the scale out again for exact differences.

but its not for everyone the price tag alone steers most away. but as fern said you get what you pay for.

yes, they work off of the exhaust pulses to help spool the charger better.

hohn not pp's work.

 

I have built headers for super stock tractor pullers for 3 turbos and they do crack, I have not used stainless for them although the tractors are put to the max heat.

 

and i'm not saying they are indestuctable because anything can be broken!!

i personally cracked a 3pc. manifold on that they said "that would never crack because it has the ball socket construction". but it did! wether i abused it that hard or it was a casting flaw i don't know. i tend to think mfg casting opps.

so i'm headging my bets for this beautiful piece of craftsmanship and putting it through it's paces. and if or when or if ever it fails i'll be the first to call the mfg on there warranty. but just like everything else nothing last forever and holds up to abuse for ever.

i'll keep you all updated.

 

who makes them then???

 

What grade of SS are they? This is vital info. for anyone interested.
