Some of the things that make it different are the following:
Exhaust Manifolds are much different. The XLR-V's exhaust manifold has a wicked kink on one of the banks. Very pinched off system!!! The STSV for the most part is pretty straight forward with its exhaust manifolds. The XLRV also uses a slightly different tune. You can very easily pick up that 26 HP through a tune. Also the air intake system is different. XLRV uses twin filter design located on the front of the car and the STSV uses a single filter. Those are just some of differences to why one makes more power than the other.
Just FYI - From a tuning standpoint we can actually make more usable HP & TQ with the XLR-V application!

Don't they have the same engine and drive train?
Why is the XLR-V down 26 Hp?
