well i was looking at the resonated pipes...
http://conceptzperformance.com/Cart/...ion.php?II=890
It states that they will not throw a CEL after install, and that with the in-line resonator, you will not hear a "rasp" between 3-4K like other TP's
But they ARE the same price as the HFC's they offer.

I wish i could make up my mind...I want to order today!

Well you've already got an intake, plenum, and catback exhaust. The only other breathing mod you could add in there is headers and/or cams. Both will be expensive and probably not worth the money. If I were in your shoes, I'd get the HFC's and then get a tune.

I'm also looking at the DC headers right now.

to the OP, are you talking about an actual tune on the dyno, or just a reflash?
Curious because I'm starting to do the research of tune vs. reflash. Especially since the closest shop I'll trust for a tune is still 4 hrs away from me.

An actual tune on the dyno with UPREV. I found a reputable dealer close to me called Xact Dyno in Tempe. Its $400 for the software, and $300 for the dyno time. So $700 gets me out of there with probably a nice extra 30 horses or more with the mods I will have, and just a 'better' running car.
dude just get all ur mods done then get the tune instead of doing it twice..if u are gonna stay n/a and not boost it, then do the headers, cams, intake, plenum spacer, high flows, cat-back and tune it..will be a decent car then..

K&N Typhoon Intake
Kinetix V+ Upper Plenum
DC Sport Headers
Kinetix HFCs
HKS Knock-off exhaust
NGK Iridium plugs (If that matters)
After the tune by UPREV, what kind of gains can I expect? total, compared to stock

Not always the case but it's likely that your car will run worse after you add the headers. In my case, my '05 350z ran worse after I added HFC's and headers the same day. Luckily I had it tuned a few days later, which made a huge difference. No one can give you a real number on the gains on the tune but it will make a big differnce. And TBH, I would skip the headers, save the money for other stuff. Been there done that.

What if you have all of those mods and don't get a tune? Is it bad? I have all these mods for my Z but its not tuned. I don't want to mess with the ecu/computer because once smog is up im dunzo!
if u are staying n/a uprev offers a nice dyno tune with a flash for the stock ecu and aam offers the same..dont go with a mail in flash get a real dyno tune
wrong quote on last message^^^
I first got CrawfordZ high-flow cats, and blew them out. Then I went with Berk high-flow cats, and I got the metallic ones so they would last on the track. Unfortunately, they didn't last on the track, they blew out. (whole thread here), so I ended up getting kinetix resonated test pipes. The sound of these test pipes is as good or better than the high-flow cats, to me.
If you drive on the street, high-flow cats will probably be ok. If you drive fairly aggressively on the track, I would (and did) go with test pipes.
