Got test pipes/hfc's on your HR? Post in here.
I thought it would be a good idea to have a thread where all the hr folks can post what test pipes or hfc's they have. I guess it would be helpful to list what brand you have, and how many miles you have put on them. And comment on their quality (whether or not they cracked). I'll start off. 
I have berk hfc's. I have been running them for about 27,000 miles now, but today I noticed they have cracked right at the support bracket! Now I have a reason to buy new hfc's.

I picked up a set of used fast intentions resonated test pipes. I got a CEL with the brillo pad trick... However these are their earlier design without the longer J bend for the O2 sensors. No cracks or anything yet.
However I am considering putting the cats back in just because it is so incredibly LOUD with my Greddy tic dual exhaust.

I was dead set on Berk HFCs, my shop talked me out of it and suggested Berk TPs instead. Very happy they changed my mind because the test pipes are awesome. Here's some info I can offer (keep in mind I already had the Injen dual exhaust when I had these installed.
To summarize them, they added about 10 whp, which was nice. It was hard to tell how much they actually gained alone because I got them installed and the car uprev tuned at the same time, but it was the first time I felt a noticeable hp increase. They make the exhaust sound better/more aggressive and significantly louder, but rasp near full throttle at a certain rpm range. There's a slight smell of gasoline like all test pipes, but not enough to really bother me.
Overall very satisfied. Great bang for your buck.

I have some AAM I think non-res test pipes. Got the CEL for a bit, then went away, then came back on and stayed on. Rasp is irritating, so bad I took my Tanabe off and put the stock muffler back on. Power gains are no doubt there, so they've stayed for now, but they won't be on there forever.

yep gtm resonated test pipes was what I had in mind. I don't see many people running them though. Need some feedback on them.
This time I wanna try resonated test pipes, and the only brands that make them for the hr are fast intentions and gtm.
I don't wanna go back to stock cats, that will make me sound like every other z out there.

I bought Berk's a couple of days ago, didn't know about the GTM resonated test pipes. I have HKS exhaust right now and I plan on getting this installed in day or two after my midterm. Or should I try the GTM??

Both GTM and FI are good, I think it's a matter of personal preference which one to get. AH has the fI* ones with a fi exhaust, but he hasn't been on in a while. Try shooting him a pm or looking at his threads. The quality on both of them is good, I think fast intentions might be a lil cheaper than gtm.

I have Fast Intention's resonated test pipes with an HKS exhaust. Just put them on a couple of days ago and the sound definitely increased, at higher rpm's there is some rasp. I brought them used and one of them was cracked by the resonator but i got it rewelded and its fine now, also did get a check engine light on.
