ARH Shortie Headers Pick Up Huge Gains For Turbo Builds

[SteveDoten@ARH]

Jeremy at Power Fab Automotive recently installed our ARH Shorty Headers on a customer’s twin turbo Gen 5 Camaro. Jeremy’s standard TT kit was designed using factory cast iron manifolds, but Jeremy decided to put ARH Shorties to the test for a back to back comparison. While it would seem logical that the headers would increase power by spooling the turbo more efficiently, Jeremy was shocked with the performance results. Without any other changes, the Gen 5 picked up +38RWHP / +74RWTQ at peak! Gains throughout the RPM range were even greater where HP increased by 70 between 4000-5000. There was absolutely no change to the tune in back to back testing. As a direct replacement for the manifolds, the swap was quick and easy. The results were no surprise to the ARH team. The best part is that ARH Shorties are made using the highest quality 304 S/S allowing them to withstand high boost applications. They are also 50 State Legal.

Quote from Jeremy- “With the gains we’ve seen using the ARH Shorties vs. cast factory manifolds, we'll easily take the 1000RWHP stock bottom end record. It’s just a matter of time!”

How much for a set of those?

And will that set fit wit the Turbonetics kit for LS3

I currently have JBA catless mid pipes and stock manifold

[Camaro Dude]

I love those torque increase figures

Thank you for bringing this to the table.

Man I miss turbo'ing..

I've always thought that the exhaust before the turbo's doesn't matter that much. Interesting.

Size of primaries?

Thanks for the good words!!

Will they fit the Turbonetics kit?

[Steve@SNL/Monster Clutch]

I can vouch for this, while we didn't do a side by side comparison they easily supported Bull's 1280 rwhp in his 5th Gen SNL Performance built. The car made over 1,000 rwhp on 20 psi and pump gas/meth.

These headers are a fantastic addition to those doing turbo kits, great job ARH!

Too bad they were in stock for the baller twin charged zl1. Had to go with another brand.

Nick, We tried our best to get them completed, but couldn't get them done in the timeframe needed.

Yes, the Turbonetics kit uses stock manifolds.

These are direct replacements for stock manifolds, so as long as whatever turbo kit you're running is currently bolted to stock manifolds they will bolt right in place without any issue.

That's awesome gains but I'm not buying the no retune needed. anything that is adding power is going to need to be accounted for
