They are both good kits, in fact I had a very hard time choosing which one to get. It's just a matter of which one YOU like. The Star kit comes with a rather loud intank fuel pump, but then again, I have not heard HRC's kit. The HRC's kit ( I have heard ) requires welding when upgrading this kit to it's second level. But then again, Star's kit does not come with a Flex section in their down pipe. But it's said that you don't need one unless your pushing major power, and it's simple to add one.

Just do a lot of research and then choose which one you like better. I chose the Star Stage II kit cause I liked the price, and the chrome pipin Also, I like telling people I have a Ball Bearing Turbo:-) But you could also get the BB turbo from HRC (And it's just as durable as the one that comes with Star's)

I use to have a White 99 GS Sport with a Star Stage II Ball Bearing T3/T4 turbo...it was fun untill....well those who remember me know Oh Ya...this is what I have now... a 99' GSX...
