HFC Vs Testpipes
You keep proving my point but just don't understand what's going on...
I would hope your Berk and APS test pipes made good power without issues - it's kinda hard to mess up replacing a catalytic convertor with a f*cking pipe.
i think u are highly underestimating who u are talking to..ive been around a minute and built many cars, if u really think i cant put a non fouler on or something along those lines then idk what to say and have no interest in commenting on anything u have to say nor does it matter, i did not buy my berks because of the non foulers but some may and theres no problem with that....check my350z if ur really concerned im there also before being here..i guess u know best though 
...my berks seemed to do fine ..my aps test pipes seemed to do fine..my berk high flow cats failed after time..my invidia high flow cats seemed to do fine..ive been around the block..i will say i made the most power and ran the best times with my berk test pipes over any others tested. have fun playing with non foulers

Lol you guys are hilarious. Given the fact that the Tyler dude is whack. In answer to your question dofu yes indeed it is cheaper and not a hassle at all to buy hardware to make non foulers. Id say go that route if you want a certain type of HFCs without the non foulers.

Dude are you serious?^^^^^ Please don't post garbage just to post.
A resonator is a chamber that muffles the sound, and a HFC has cat material (cells) that helps muffle sound and remove emissions from the exhaust. A non-resonated test pipe is just a straight through pipe.

An HFC is just a high flow catalytic convertor - a catalytic convertor that is much less restrictive than the ones your car came with.

That depends on where you are. In CA, neither will pass visual since aftermarket cats are illegal as well.
