I was getting bored with the stock Z so i decided to add a few things.
Rims and tires were first.
Second(and last for the week) was a Pro-1 Exhaust.

I do have to say it does sound absolutly amazing. Although if you run it without the sliencers/baffles it becomes extremely noisy. With the Baffles if it sounds amazing.

The base line dyno
RWHP: 243 Ft/Lbs Torque 235
With the Pro-1(baffles out)
RWHP: 250 Ft/Lbs Torque 238
The Pro-1(With Baffles)
RWHP: 248 Ft/Lbs Torque 239

I will get my scanner going and show how much this actually smoothed out the torque line sometime this week. As well as show a quick dyno run with my car. With the baffles out.

Total overview: The Pro-1 exhaust is a nicely designed exhuast system that does add a little bit of horsepower. If you are not looking for something that gets really loud without a silencer this is not the exhuast for you. If you dont mind running a silencer it sounds amazing. I have been told my car sounds like a Ferarri. Overall for the price you pay with the performance you get it is a great system. It would be highly reccomended by me.

Here are a few pics of the Rims.

When I figure out how to upload the video I will do so.
As well as get the dyno charts up.

 

When I had my Pro-1, it sounded like total garbage with the silencers in. It's raspy from the time you turn the key.

It sounds pretty nice with the silencers out, but it was too loud, especially on the interior of the car.
