Of course test pipes will perform better.
The question you should ask yourself, "Is it worth switching to test pipes?" Let's say you do switch, how much horsepower do you think you will have gained? Will you be able to notice that marginal increase in power? Will you like the exhaust sound after the switch to test pipe??
I think the HKS sounds like crap with test pipes but that's just me.

^ I agree I had helix test pipes paired with the hks and it sounded terrible, I now have crawford hfcs and I think it sounds great! Plus I couldnt tell the difference between tps and hfcs.

Stay with HFC's... Switching over to test pipes will give you a SMALL gain if any over your current setup but will sound raspy. I wouldn't do it personally. Just my .02...

Once I had a Berk non resonated test Pipes with my HKS then I switched to Crawford HFCs because of raspy sound. Non-resonated tps will give raspy sound. Try with resonated test pipes. You will be fine then

The difference between the two will be small/un-noticeable. Like David said, if they are going to look under your car for cats then I'd advise against it. Take it from me, I started out with test pipes with my hks hi-power and it was way to loud and raspy for my taste. I since switched to berk hfc and am quite satisfied.

I disagree. Test pipes you will loose power 2k-3.5k (rough estimate) With any test pipe there is no back pressure wich will cause the exhaust to free flow out. You need back pressure to keep low end power. IMO if its a DD you want to go with HFC. TP will gain a LOT of power up top that's why people for for it.
HKS does sound like crap with tp

Also worth saying is most HFC dyno so close to test pipes now a days with 300-400cell cat setups there isn't much point (other than cost). Plus remember with out a cat the car is polluting as much as 30 cars does. I'm not a tree huger by any means, but all that pollution for 2hp? Just doesn't seem worth it really.
