Does anyone know anything about speeddaddy's catback?

 

I have it

It's bitchin'

 

I didn't measure them when I took them off but I'm pretty sure the factory exhaust pipes are at least 2 1/4" so the Speeddaddy stuff doesn't look like much of an improvement.
If its a price thing, check these guys out. Home page
The factory exhaust (-cat) is very good and you'll will only gain a few horsepower from a full replacement.
