Any dyno charts showing gains????

Looks like excellent quality.

Deffinitely want to see some dyno results as well.

When we get a chance to do a before and after dyno test we will post it up, currently our time constraints do no permit us to do so.

Well I am sure that everyone is anticipating this day when we can hear and see the dyno. Great work on the product.

Any resonated test pipes? Some people would prefer not to sound like a fart can :o

Would not spend the money without knowing it did anything or not... :(

He is going to post it soon. Have patience.

The test pipes WILL make power. You're removing a huge restriction in the exhaust path.

In the next few days the results should be in, maybe even sooner.... :D

Results are in....

very nicely done!!!

Wow!! Really nice gains for test pipes!! Are you guys reflashing for the TPs?

Awesome.

Even more interesting is the bone stock 370Z dyno.

No, this was just bolted on, then dyno tested.

Next will be our GTM cat back exhaust with test pipes, again no reflash since most people purchasing these parts won't have a flash. The gains should be awesome with some tuning though!

Wow amazing gains. George, you guys are just barely touching 300whp with just test pipes. That is pure sex!!!!! Cant wait to see what your exhaust system does. Good job. :tup:

Question...what is the pipe diameter of these test pipes?\ 2.5inch im guessing?

nice numbers... cant wait to see it combined with your cat back..

Awesome numbers!

Those pipes look like they fit like a glove.

Please keep us updated on a catback!

george can you tell us if the y pipe is the same (lenght etc )as the g37? because the two cars are not the same lenght im woundering if the centrat pipe or the y pipe are different than g37
Thanks

Are you using O2 sims so you don't get that annoying check engine light?

any issues passing emissions? So this replaces cats?

No cats = emissions no no

Post some sound clips ;)

Any ETA and pricing info on the catback ??

Well that is the reason for the o2 sensor tube that it is installed in on the test pipe. Less air gets to the o2 sensor so it reads as if a cat were in there.

Next week.

+1

I want sound clips NAO!

Price drop!

Cel? I know you did that thing to prevent it, but did it work? Has it worked long term?

Yes sir! We haven't had a check engine light in over 4,000 miles on some of our customers cars.
