G35 Coupe 03' - 07' Motordyne Mrev2 Lower Collector

I have a 2005 G35 6MT with a revup engine. After installing this manifold I def noticed a power increase after 5000 rpms. I actually noticed the power increase the day after the install. The day of the install I was upset because I didn't feel a thing but after letting the ECU adjust itself, It kicked it. I'm extremely pleased with this manifold. Can't wait to add the 5/16 plenum spacer soon. I def recommend this if you have a revup engine.

Sounds great after about 4k rpm
