Your GT does have an L36. L36 is a series II naturally aspirated engine. I would not take the runners out. You might gain horsepower but you will loose a lot of low end torque. If you want to remove the runners and gain HP and Trq you need to buy a HV3.

It'* an Insert made by ZZP. http://www.zzperformance.com/grand_p...=214&catid=113
You can usually pick one up used for $150 or so.

Cutting down the runners in the insert is something guys do. I'd never suggest reomoving them completely. The HV3 has been determined to be the proper runner length. So cutting the plastic runners in the stock manifold would help.

like Justin mentioned though.. it'll change the power curve
