I had my FI Tp's installed a few days ago by Specialty Z and just today the CEL turned on. I will try resetting my ecu to see what happens.. $200 for the install seems about right. That's what I paid.

Same happened to me - light turned on a few days after install but hasn't come back since resetting ECU ~4-5 weeks ago.

L0L! I'm just say'n that eventually the CEL will come on no matter woot test pipe w/rear 02s installed w/no reflash IF driven for over 500 miles consecutively! That's my guesstimate....Any1 have any real world xperience w/this?

I have never had a CEL. and my only "reflash" was when I got tuned. after my installation of mine I drove it for a year or more. added my intakes and got tuned. have been driving it since then no issues even with straight pipes now I have no CEL.

i'm telling you FI test pipes are the best for sound, power, and no CEL. if it throws a CEL they work with you to fix it.

most CEL's come from people mishandling the o2 sensors and breaking them.

O 5h1+! L00K @ that?! Sum1 w/FI test pipes had their CEL lite up! LOL! Like I said, the only way to never see this BS is to have a reflash...
And the "demon bolts" aren't **** if u brake 'em within the 1st 1K miles of ur Z34....My Snap-0n 2ft, 1/2" breaker bar made quick work of 'em...had my kittens and hole OEM Xhaust off within 90'....Basically, U don't want TIME/HEAT/RUST to G4ld the "demon bolts" on more than the ~150ish p0und FT o tork the FAC sets 'em @....OEM FSM states "33 lb ft" LuLZ!

W00+ was ur consecutive mileage w/out a reflash run'n test pipes? A test pipe is a test pipe, who R u try'n to F00L?

yes consecutive mileage. I DD the car except for when it's snowing. that's the only time my car doesn't get miles on it.

i'm not trying fool anyone. you'll have someone from time to time get a CEL with FI tp's, but they will sort it out. again almost every time I've seen it happen it was due to the fact the o2 sensors were not handled properly.

LoL! Once again, have u ever taken a RD trip in ur Z, 500+ miles w/out shutt'n her down? I luv how ur :nutswinger: on FI...LuLz! R they sponser'n u?

purchased car in LA: 1300 miles straight home to PA
va beach: 500+ each way
ZdayZ multiple times; 600 each way plus 200 or so while there
DC (few times a year): 275 each way
etc etc etc

yes I've most likely had more road trips than you could dream of my friend. now please :gtfo2:

Really?! and all this dun w/out a reflash? LuLz, I'm dun. Is their a vid / U-tube proof of this 12.9 1/4 run? I'd enjoy watching it....better yet, did u run @ the Z day Z and vid record it? I really don't have much time off, so any linx would save me time....;)
Yes, U've definitely dun longer RD trips then me...but I'm make'n $$$$$$ over seas....and as I said, an individual did have a CEL on his FI test pipes...so I FIGUR3 I win that argument....;) :rofl2:

So what you're really saying is you have no fuckin clue what you are talking about. Got it :tiphat:

Um nope.
I have thousands of miles on my test pipes with multiple trips over 500 miles.
Stock tune no CELs.
Also have track time on my test pipes too.

Had demon bolts on my CBE with less than 1K miles.
Had to cut of 2 bolts CBE side of the cats.
This was at my buddy's shop and he has 20+ years experience as a mechanic.
Also he specializes in Zs.

cant speak English, knows nothing about 370's, but making money overseas......sure. but here you go troll. all of what you asked for.

small feature as well just as a bonus:

N1CE! Glad 2 hear it! LuLz! I really shouldn't be talk'n sh1+, since I removed my rear O2s and had my rear O2 bung Xtensions cut off and welded shut....
My CEL is @ least throw'n 5 codes as ov current...two for rear O2s and three on my EVAP delete....L0L! not that I'm skeered....O! N I also have 1/4 track time on my Z34 too! :eek: I find it funny that most driver's of the Z R skeered ov a little CEL lite...if u have the proper gauges, then u'll kno when ur Z is BR0K3....
