Wow it took like 2 hours just to bang all that shit out, but it was worth it, some of you guys said you lost alot on the bottom?? I didnt lose any at all. Infact it did feel a little smoother throught the P band. That fuckin stock exhaust has to go.. it's so heavy I weighed it on my scale and it read 13 pounds.

I agree, I did mine last week and I love it, I notice the same thing and a little bit more raspier exhaust note, not much but for free why not!

No sir, as long as you hook the SUPER AWSOME VRROOM VALVE back up you should be good to go, but as your "gutting" it your going to have to turn it on and the valve will be removed therefore the FI light will come on so dont be alarmed. If your really considering doing this you better have some time on your hands. It may seem that the shit your trying to bang out wont come out but trust me it will lol..

IMO, the biggest advantage is that you average about 10 degrees cooler exhaust temperatures.

The CAT is down in the collector so removing it would have the same overall effect with the stock or slip on muffler. I noticed a drop in exhaust temp as well which results in better thermodynamic efficiency. A more noticable change was the engine temp drop when I went to a manual CCT instead of the oil pump driven one.

If anything it should lean it out because of increased airflow.

Not if you like the way it sounds. Probably better on the motor too since exhaust pressures would be reduced.
