sure... but you will lose midrange torque and unless you get a technosquare reflash to raise your rev limiter, you won't even get up to the RPM range where it does make torque
I tried this, it didnt work on my car, many others have lost considerable midrange and made minimal to no gains up top. I can only think of 1 or 2 guys who say it works for them.
Revup lower plenums are just for revups. The exhaust cam phasing helps for the high rpm usage with this manifold, plus the higher redline. The loss of torque is given when you have a intake manifold that is made for high rpm peak power.
And the odd thing is, you can make better high RPM NA gains with a spacer (or upper plenum) than by changing to the REVUP lower collector. ...And the spacer doesn't lose midrange or TQ either.
Unless you are reving to 8K+ RPMs, I wouldn't suggest using a REVUP lower plenum. It loses too much area under the curve.
