D3 is always looking for new ways to bring bigger and better products to the public. Our latest product is headers with high flow cats for the XLR-V. This bolt on modification replaces the existing restrictive exhaust manifold/catalytic converter combination. **The result is an additional 31.1 rwhp and 37.7 lbs of torque**.
**Our stage 2 XLR-V, which previously produced 460.1 rwhp and 476.8 lbs of torque has jumped to 491.2 rwhp and 514.5 lbs of torque by adding the headers/high flow cats and retuning the vehicle to match the added airflow.**
This component will be moving into production shortly. Please contact your sales associate for details, pricing and availability.
Pictures will be available after they move into production along with pricing. I don't think I have any available video clips of the car (now) but I'll check. The car sounds awesome, IMO. And amazingly enough, with the Corsa exhaust it still doesn't drone.
I can't wait until my best friend graduates as she plans to get an XLR-V and I want to drive it...and convince her of what mods to get.
The 31 hp claim is a little misleading using an already modified car. Any testing on an otherwise stock/catback only car?
Sorry, but the work and testing D3 did on the XLR-V headers was on a stage 2 or near stage 2 XLR-V. While those horsepower numbers may not be exact on a stock or near stock vehicle, I can tell you that one of the most restrictive points and limiting points for making higher hp numbers on the XLR-V is the headers or rather, factory exhaust manifolds and cats. The factory intake is also a HUGE restriction as D3 found out with the release of their intake systems. Both produced very respectable numbers for not a lot of money. I highly recommend the intakes and headers to anyone looking to boost performance on the XLR-V.
We did build prototypes, but we never moved forward with production. If we can generate enough interest we would look to build a limited production run... The STS-V application was actually more difficult, but certainly doable.
As for the V2 rear diff swap, no go if you are just trying to do a bolt in. The rear carrier is different. We are offering rear diff upgrades for the XLR-V. We have to see if the STSV will accept the same built rear diffs... I will let you know.
p.s. We have some dyno footage of a few different XLR-V's with the headers installed we will be posting soon!!

I'll also put it to D3, a CTS-V2 diff swap to STS-V or XLR-V option?
