Catalytic converter cracked Videos

Sounds pretty good. So dark it's a good thing we don't need to see...

That sound is with open headers - meaning there are no mufflers or resonator. It was way to loud for everyday use, but kinda cool for 30 minutes :). I have done a lot of work since I made that video. I have done all of this on a very small budget. Here is the order I did things: 1) K&N drop in air filter and remove sound baffle (don't buy a short cone filter - they're actually worse than the stock airbox because they don't pull air from the fenderwell) 3) 3 inch down-pipe - I got one with a high flow catalytic converter 4) Cut out the resonator and replaced it with a straight piece of pipe IF you want more sound through the stock mufflers (it sounds pretty crappy until you do the PCM to be honest) 5) Tower strut brace - CRUCIAL if you want to reduce horrible understeer 6) Colder spark plugs and wires - I went with TR-6's 7) 180 degree thermostat and throttle body spacer - for better cooling 8) ZZP 1.0 PCM 9) 3.5 inch supercharger pulley and oversize 3.5 inch tensioner pulley The expensive things I really want now are wider and stickier tires (I want 255/45/18 at all corners which won't throw off the speedo), an intercooler (these cars run sooo hot), coilovers, headers, injectors, and a light cam. I probably won't do any of these things because I don't want to spend the money, but that's how to get the most out of your GTP. I buy almost everything from ZZP. The company is great. If I had to pick three things from this list, I would go with the ZZP PCM , the tower strut bar, and the K&N drop in filter. That's a great place to start. Ask me questions if you have any.
