No feedback on either, but they are both non-resonated and I personally would not recommend them as such. I have Megans, which imo are hit and miss. Sadly, I think mine are the miss, as there is a slight rattle at low throttle at about 2000rpm, which I suspect is due to a poor quality resonator. Others have not reported this problem, but considering the price of these things, and the work involved with changing them, I haven't bothered having them warrantied. I'm planning on replacing them with FI or Kinetix test pipes next season (or any other decent brand of resonated test pipe), and I'm gonna sell these for cheap to someone that doesn't care about a slight rattle. It's only audible if my windows are closed and my music is quiet, but I'm **** retentive about my car, and even the slightest imperfection drives me into a fit of rage. If you're the same way, stay away from Megan products.

-You will get rasp
-Sound depends, What mods do you have? Which exhaust?
-Power, I would suggest you do a before and after dyno... This is the only way to tell if you have made any gains.
I ran test pipes for about 5 days. Paired with my nismo exhaust. It sounded amazing at WOT, its just to bad I don't drive at WOT 95% of the time...
My honest opinion was that it was to obnoxious for me.. I was almost embarrased to drive my z..
I switched out to BERK HFC's and loved them.
You need to provide more info on your setup:
-DE/REVUP/HR motor?
-Mods to date

Check out some clips on youtube, I'm rather fond of my stock exhaust + resonated test pipes combination, but if I were to get an exhaust, I may find it too loud. Either way, I would recommend you steer clear of non-resonated TP's, and decide between high flow cats and resonated TP's.

Reality sold me his Helix V2 afterwards, I matched it up with Injen Angled SES. It was RASPY as hell, and LOUD as hell. But afterwards, I switched to stock exhaust with the Helix, it sounded like VQ heaven. Not too loud, No rasp at all, just perfect. If I had known earlier, I would have ran this setup the entire time I had the Z.
You will not pass emissions with TP's and stock exhaust. Those two cats are the only cats on the entire system. No pre-cats, no-post cats like other cars.

Haha, yea, definitely no passing e-test without the cats. I should take a pic of what my tips look like at the end of one week of driving before I clean them. It looks like a flesh eating disease is caked on them. It's some scary stuff, I almost feel bad about spewing it into the environment.
You can also smell it if you're behind me, and even I can smell it if my windows are down at a light or stop sign. The trippiest part has got to be the fact that standing behind my car will cause me to tear up. The only other car that ever did that to me was my buddy's RX-7, and we all know how environmentally friendly those premix running bastards are

^I could never smell my test pipes unless I'm going in reverse fast.
Never had to clean the Injen tips that much because they weren't rolled or double walled like OEM and nismo hahaha

test pipes
awesome feedback guys.
i have a magnaflow catback, k&n drop in filter, motordyne spacer and mrev2. i have the rev up engine.
i'm basically looking to gain some more power with one more mod. Should i go hfc, UR pulleys or y-pipe?? or should i not even bother cause it won't make much difference anyways??
thanks again for the insight.

Pulleys, get the one for AMS. I already noticed a huge difference just from Lightweight oversized crank pulley on my mr2.
Then HFC
Then Y-pipe
Then something to tune it.
Or if you feel like it, all of it at the same time

My experience with AMS pullies:
-Definite improvement in throttle response
-Noisey, almost irritating at times (sound is similar to slipping belts)
Would I do them again.. probably not.
Skip the pullies
If I were you...
-Berk HFC (warranty is excellent. And Bryan@BERK is a great person to deal with)
-XYZ pipe from Motordyne (if you are going with TP's, then get the single cat for the XYZ pipe)
-Emanage Ultimate piggyback
Then head to Ed's shop for a dyno tuning session!

stock cats
why wouldn't a person just knock the ceramic stuff out of the stock cats and have a cheap test pipe? or there are actually two cats in the stock cat one before the o2 bung and one after. you could knock the ceramic stuff out of just the second one and the computer would still be alright with that and gain a little less restriction? has anyone done either of these things?
i have berk test pipes and a nismo exhaust it sounds like garbage!!! i am embarrassed to drive the car.

I didn't do it because I don't plan on keeping the car forever, and I want to be able to sell it. So I'm keeping any stock part I take off it in my basement, to return to stock before selling.
