Hacking your shower head: 2.5gpm a minute and flow rate limiters

Federal laws put strict limits on the maximum flow rate for shower heads, of 2.5 gallons per minute. Many shower heads do not even reach that for fear of exceeding the limit and the strong sanctions the company's would face for selling such a shower head. If you pay for your water, the amount you use to shower should be up to you. Some shower heads offer a convenient law work-around: a plastic washer or screen is used to set the rate limit, and can be removed. It's not something they can advertise online, however, so it can be hard to find one. Here's a list of what I've tried, and what level of success I've had.

Peerless massage shower head, "4-spray SH-chrome", model 76456. No obvious rate limiter to remove, and out of the box it's like showering in a light drizzle. ~$13 at Walmart.

Waterpik power spray 4 setting (model sm-423cg). The back of the box advertises a removable flow limiter. The included diagram shows a water filter and a separate rate limiter, but in my shower head I could only find the filter. Removing the filer did improve pressure, to a level much better than the Peerless above, but still weaker than I'd like. Maybe I didn't find the rate limiter, or maybe it was missing, but in the end this shower head was only satisfactory, not awesome. ~$15 at target.
