A good place to start is with a CAI or a ram air intake. If you have an SE/SLE/SSE, open the exhaust up to 2.5" and start from the CAT back. I personally like Dynomax because it has been proven to be the best flowing muffler in its class, but its all about preference. Also be sure to install a 180 thermostat to keep the engine running cool and help it last longer. Oh, I almost forgot, upgrade the wires and plugs. I personally went the extra mile and got MSD Super Conductors, but Taylors do the job as well. Do not get Platinum plugs if your adding alot of boost, nitrous is my case (also if you have a supercharged model or are planning on a turbo installation). Do NOT, I repeat, do NOT get any bosch plugs, wires, O2 sensors, etc. They burn up and can do damage to a 3800 engine. Once you complete these steps, go for a mod chip. But chips greatly rely on what model and year Bonneville you own. If your interested in a chip, get back to me with your year and model.

Once you're done with the above...GO NUTS!
