Thanx! That definitely helps. I had considered them (prolly for the price $399.00) but I guess you'd get what you pay for. I'll look into the G-Force Upgrade.
97SE 5 Speed, Stillen intake, Focuz Muffler
Planning to get: ECU upgrade, UPRD underdrive pulley, Short Shifter, Y pipe, 2001 Maxima Muffler, Lowering Springs and struts, clear bumper lenses
