does it help out??? like i no its gunna make it louder..but is there a differnce in torque or hp??

avalosp

there is suppoesed to be i mean the engine pushes the gas (exhaust fumes) through the tighter headers then moves to the high flow cats so and can move quickly so if you have some wide pipes then it should help you wont see drastic changes but essentialy there will be some thing even if its a little more hp thats a gain but as i was saying yea its better for the engine to realease those fumes quickly

Do you have emissions testing in your state? If not I would just cut the cats out and replace them with straight piping. If you are set on Hi-flow cats go with magnaflow everyone on this forum who has them likes them a lot.

In terms of programmers get an edge or gryphon programmer. They are essentially the same thing except that gryphon is a custom one from power hungry performance. I have an edge and I want to get it upgraded to a gryphon soon.
