[QUOTE="xstatic, post: 434859, member: 6026"] By removing the cat converter, it will only "release" the existing hp thats already in the engine, it will not increase your hp, since your engine is only rated up to what it is suppose to produce. And by having a less restrictive exhaust flow, meaning your engine will breathe better, thus the xtra power you feel at higher rpm. Having said that, it will not improve your low end torque (better pick up). [/QUOTE]
