Racetronix 99+ installed
Only took a couple of hours to do the job, including dropping the tank and everything. I have true duals with turndowns before the axle, so I didn't have any exhaust parts in the way when it was time to remove the tank.

The pump is very quiet seems to be just slightly louder than the stock pump in my car, though I have seen others post that the racetronix makes less noise than than thier stocker.
After driving the car around and doing some nitrous runs, I am very happy with the kit. The car seems to run better on the spray now. I was probably beyond the limitations of the stock pump.
This post by racetronix has some more good info on the install.
Mount the relay and spiked chassis ground lug in front of the DS rear tire using the factory bolt as shown in here:

Clean mating the surface and the bolt with a wire brush to expose clean metal and apply a generous amount of silicone grease supplied to prevent corrosion.
Plug the harness into the chassis and the fuel module into the Racetronix harness.
Insert the connector locks (F98=red, F99+=blue).
Route the harness along with the fuel lines under the car. Secure the harness every 12" with the supplied wire ties.
The harness power source may be hooked to the alternator's + output (best) or the + battery terminal.
(If you chose to use the battery as a power source run the harness over the top of the transmission housing and up the PS inner front fender well)
Route the harness such that it does not rub on any sharp surfaces or come to close to any hot exhaust pipes.
Mount the fuse holder with the supplied self tapping SS screw in a location where access is possible if required.
Hook the harness + power to the alternator output stud OR the battery + terminal using the supplied brass battery.
The factory battery nuts are removed by pressing them out from behind the terminal boots.

Install the body ground upgrade cable. One end hooks up to battery - and the other end to chassis ground.
The screw on top of the battery nut is considered the accessory tap. These are installed after the nuts are secured to the battery.
The extra connector set included with the system is to interface a pump booster if required.
The mating connector on the harness is located just after the relay.
