We are getting set up to dyno the TDX cat back with our HFC's...

Holy ****, Im in for this

Pm'd

:rock:

Videos tomorrow? :tup:

Hell yeah...nice #s!

OMG.. :eekdance:

Those numbers are awesome..!!!!!

+20hp for just catback! sweet! I love the VHR!

forgive me if I missed this but this is 2.5" correct? If so, any plans on making a 3" for FI setups?

Yes it is a true dual 2.5" setup. Possibly down the road for the 3"

We already have a 3" available for the VQDE/VQHR 350Z. But that does you no good!

Possibly or worst case scenario Saturday. We are still here at the dyno so it might be a late one!

Exciting numbers. Looks like you have one killer setup. Glad to see the performance came in so strong to match the awesome sound and looks. Throw in the strong weight savings and it looks like I finally will have to break down and order a cat back.

Kudos to the great engineering and design. You had to be damn proud when the numbers came up on the dyno.

I am VERY happy I ordered this exhaust. Great #'s.

w00t ! I can't wait for the video with some HFC since a lot of us will be running those..I was gonna hold out on buying until someone posted a vid with their HFC on until I bought mine but if FI gets the vid up sooner then I may have to buy sooner !:driving:

what did it put down w/ the HFCs?

Should be doing it now, I imagine itll take a bit of time to take off the TP and put the HFC on.

During the dyno runs of the HFC's & R.T.P's I started the think as to why it wasn't making more power. Then I reviewed the numbers and realized that they were pretty standard as far as gains go. Remember that this car has stock air boxes and stock air filters. The car is only taking in so much air so it can only let out so much exhaust. Now, I am confident that the HFC's and R.T.P.'s will play much more of a part when a good cold air intake setup is on the car.

The cat back itself, blew away our expectations! We are extremely pleased with the results.
Bottom line, our cat back gave a bone stock 370Z 6MT an average of 20 RWH more and 11 FT LBS. of torque over stock.

I told all of you from the beginning that we would be true with the numbers regardless of how good or bad they turned out!

After seeing gains like that for the cat back, if there was any critics, I think it put them to rest!

I have the dyno charts and I will try to post them sometime tomorrow.

Thank you all for being patient...

Tony

Good Sh!t :tiphat:

Bravo to rigid testing parameters!
I applaud you for great sound and great gains!

Hey Tony, is it possible to get some exterior decibels for the 12" and 18" resonators and HFCs?

Numbers looks great, now for the video!!

WOW! I'm impressed. Great work Tony!

great work FI! 20whp is very impressive :tup:

Hell yeah! Waiting on Berk to get their stuff finished up finally and I will decide...

Awesome results, Tony. Props to you and your team for your excellent work!

SOLD!

(when I have the money!)

Numbers on the 18" Res? Did you dyno with them?

Asking since it was recomended if you were going to run Berk HFC

Theoretically, there shouldn't be a difference as resonators are straight through and don't obstruct flow.

It will mainly be sound difference on the Resonators size, also F.I. makes there on cats, so I doubt they will test with Berk cats.

Hey Tony what does the exhaust sound like with your (F.I.) HFC's on?

Edit: Keep up the excellent work!

I have no issues dynoing Berk's cats. Since we no longer use the same substrate I would be curious to see the difference, if there is any.

My guess would be negligible difference, but you never know.

Hell yes Tony, I'm glad I preordered this exhaust from you :D Excellent work, can't wait to get it installed! :excited:

(except for the whole...I'm out of country for 1 month >_<)

Sweet! ....... I knew the wait for the FI 370Z exhaust would be worth it

Thanks again Tony

Berk or FI? decisions decisions

Someone just put a spotlight on the elephant in the forum :)

:koolaidwall:

I'm leaning strongly towards FI but am holding out to see if anything else is better so I make an educated decision :D

O.K. so here it is as promised...

it does'nt get much better than this...unless your holding out for a full dual titanium cat-back, weighs 15lbs, adds +50hp and costs <$1K :rofl2:
