DDM, Can you PM me a price on these and availability. Also, I have the Nismo catback, will I have any problem bolting these up myself??

PM sent. :)

They will bolt up to your Nismo exhaust no problem.

DDM - please PM me your price for the Berk HFC's as I'd like to add this set-up when my 370Z comes in. Please specify if S&H is included. Others are selling this for $494 with free S&H. Thanks!

got my test pipes in!! can't wait to install them this weekend! will keep you all updated. hopefully i wont break all of my tools trying to take off the stock cats

Do us all a favor and dyno the car instead of posting a sound clip.

I personally picked up 13 hp and 4 ftlbs torque from the addition of cats and Y-pipe. Every car is different, but my Vette usually picked up 5-6 hp on the top end from aftermaket cats vs straight pipes. Also post your fuel/air as mine improved a great deal below 5000 rpm but still stayed around 12 to 1 over that rpm. Typically you see the free flowing effect more at higher rpm were more cfm is flowed.

Thats interesting... Horsepower isn't crazy bad but only 4 ft.lbs. of torque?

Denny what was your baseline and % Change?

:iagree:
Any dyno results between the test pipe and HFC?

Unfortunately I don't know of anyone who has dynoed with these test pipes yet. Wanna be the first? :)

:icon18:
Working on it!

what's the price on these ? PM ME to 77566

I don't see how these could outperform completely open test-pipes.. Not unless the VQ likes more back pressure that close to the engine or something.. or Berk was just lucky to hit the sweet spot. I was going to just pick up some test pipes since there's no emission testing in Florida.. HMMM.

DD can I get a PM on pricing and availability + S&H? Also do you have Work GnosisG2 wheels in 19s?

PM sent :).

DDM,

Can i get a price with shipping to 38017? Also, where did you get the BERK sticker's i've seen on your car, they look nice. I wouldn't mind having a pair of them myself.

Thanks,

PM sent.

So has anyone tested the test pipes yet?

Not that I have seen. I know I have sold a few sets...

Well I just ordered the test pipes and jwt pop chargers. I am going to try to get the old lady to let me spend the money on a before/after dyno of the baseline then the pipes. Hopefully she lets me but from what I remember Dyno's are cheap to use. If I get those rims sold I guarantee I will get the dyno's done

^^^Sell those rims! :D

I wish I could lol.. but i cant seem to #1 find a local buyer #2 find some way of shipping them cheap

Same boat as Solus as far as wheel selling. I think there should be another group buy along with the exhaust that is comming out ! In for that !

Expect dyno #'s around mid july

I just got FI resonated test pipes.... installing them tomorow...
Going on a cruise the very next day though! (im in australia)
Can anyone tell me if this will be a problem?? Is there a 'run-in' period for test pipes or something i should be doing to let the ECU adapt or not??

Please let me know asap!!!

When I reset my ECU I found my Z drank like a fish until it adapted. Only took a couple of 100km.

Do you have to reset the ECU though? How do you do that?
HAH! this cruise is a couple of 100km so should be interesting then :S lol

if you want to, an ECU reset is easy, unplug the negative, get in the car and hold the brakes in for 30 seconds, get out, plug negative in, voila. Or you can just drive and let the ECU relearn which takes 5-10 driving cycles apparently...

So whats the benefit of resetting the ECU?
I dont want dealers to notice I have done anything either :S hahah so resetting ECU would cause alarm bells maybe?
5-10 driving cycles? lol how long are they? :P thats wat i wanna find out! :) Thanks

Dude the dealership won't know.

Just undo the negative of the battery. Hit the brake peddle a few times so theres no current. Leave it overnight.

hahaha brilliant. thanks for the advice guys.
getting pipes installed tomoro hopefully,
ill let it idle for a bit before driving anywhere.... drive a little tomoro night, disconnect the negative of the battery terminal and hold the brake pedal in, let it sit for a bit and then go on my cruise first thing sunday morning!?

:ugh2::ugh2::ugh2:

hahah
Cheers.

Can't you just pull the EFI fuses?

Seems to be a dispute over the figures here I see LOL.

Anyone actually got the dyno numbers, as it looks like the YouTube video from the original post has been deleted..

here is my thread, I made 15whp.
