George,

Do you have any drive away videos?

Skorch 04-09-2009 01:43 AM

Very interested in the group buy, but I need to head what it sounds like before pulling the trigger.

Skorch 04-09-2009 01:46 AM

Quick question: do the group buy prices include shipping to the continental US?

crbn_fbr 04-09-2009 02:17 AM

exhaust clips on dynos bug me, need a video of it without the loud dyno drowning the sound out please!

sensi09 04-09-2009 02:29 AM

Any drone with this exhaust? And would you categorize this exhaust as being loud?

LiquidZ 04-09-2009 06:50 AM

I would be more inclined to participate if sound clips of each exhaust were provided.

Ct Chip 04-09-2009 10:22 AM

Almost like they're hiding something with the sketchy info and sparse replies. Not very confidence inspiring from the (potential) purchaser's point of view. No comparison to how up front Stillen has been concerning their cat-back. Something a little fishy here IMO.

zeebra 04-09-2009 10:27 AM

Well its making more power than the Stillen though. Sounds much meaner as well.

Says who, them ? /laugh

Really, I dont want to be a prick but the mass's want info info info. Can we get more than hybrid-almost-done pictures that are actually ON the car? Can we get vids, vids, vids...We've got varied video's on almost all systems out there. Yet this has been in production for so long and we really dont have much.

They do seem to make very quality products, and I'm not doubting them but sometimes extreme customer service goes a long way!

P.S. The sounds generated from inside a dyno facility sometimes arent the best way to judge sound. Flyby's, takeoffs, anything out in the open would be great.

sylenze 04-09-2009 11:28 AM

do you have the exhaust installed on a Z right now... according to your website you are in Rancho... if it would be all good, i would like to visit and see/hear it for myself... and possibly share my experience to everyone here as well...

arcticreaver 04-09-2009 12:11 PM

omg. i REALLY like that 950 price. but dude, 15 people gotta be committed. i'll be subscribing to this thread. because if baby really makes more power than Stillen and at that price???? if you guys in Rancho, i can just go there and pick it up without the hassle of shipping. but i would like to have some videos. i can't really get the sound of the exhaust with the video posted on youtube, and since it was in a garage, all i hear is echos and stuff.

ssqpolo 04-09-2009 12:21 PM

ya 950 is a super sexy price.

arcticreaver 04-09-2009 12:24 PM

CARB exempt?

SoCal 370Z 04-09-2009 12:25 PM

George,

Are you throwing in the NISMO engine tune with these? ;)

zeebra 04-09-2009 02:00 PM

Danny they posted their Dyno graph up.. If you look at blog.stillen Stillen's cat back makes like 4whp less then theres. /laugh

George@GTM 04-09-2009 02:30 PM

The two 370s in the shop right now don't have an exhaust on them at all because they have twin turbo systems being installed on them.

Once we get a full production version on a car we will take more videos, as well as some drive by videos. At the point in time anyone who is local that would like to come down and share their impressions with the forum is more than welcome.

Thank you.

Negative. You can not compare the numbers directly as these were different dyno's, you can only compare the gains over the base run. With the stock cats this exhaust gains 10 whp.

+1

One of the big reasons I went with Stillen...

It's not making more power than the Stillen.. Semtex car made 291WHP from a 254WHP base (from another 370Z on the same dyno). That is 37WHP while still remaining legal in 49 States with the HFC's.


I can understand that they are doing turbo kit fitting on BOTH their 370z. That is pretty exciting, however it seems like GTM disappeared for for a month and came back with 2 new pictures and a price tag. Obviously I am biased because I bought the Stillen exhaust already, but that doesn't take away from the fact that there are barely any audio clips, they still have pictures of their prototype, they completely ignored my question about what the sparks were flying out of their exhaust in the last video and they ignored everyone in the forums for the last few weeks. Meanwhile Stillen was sending parts out for independent customers to test out?

Nothing personal GTM, but customers need to be informed before they spend money, specially so in these hard economic times. I thought your exhaust sounded awesome when I heard your dyno clips and had cash in hand ready to pull the trigger, but in the end you kinda made the choice for me :(

I am eagerly looking forward to your test results and your upcoming video clips! I still think your exhaust sounds great.

EDIT: also..theres a vendor for sale section in the forum...we dont need 3 threads about your exhaust on the intake/exhaust section of the forum. One would be good enough.

I am sorry you feel that way. The exhaust wasn't available for purchase then so we wouldn't have been able to help you out at that point in time.

I don't understand the "fishy" comments, an exhaust system is one of the many parts we are developing for the platform with more to come.

For those that don't know, we don't just develop products, we build and tune cars - everyday. Hence why we are so busy and sometimes miss some posts between the various forums we are active on.

If anyone has question that they need answered right away feel free to give me a call at the shop.

A cat-back exhaust made 37rwhp? you are directing your fishing comments at the wrong person :D

George,

I was there the day the car made 37hp over my stock 370z. it is very legitimate numbers and that power is made on forged performance's dyno. Which is very well known to make lower than normal numbers. I am patiently waiting for your products as Sharif and I are looking to work together on a big project with my 370z using alot of your products. I understand the workings of a shop and believe me it gets busy (I work on race bikes). I would love to see a final production exhaust with the option of titanium or burnt steel tips 4-4.5" wide that would be killer! I believe no matter what exhaust you slap onto a 370z if its designed right its going to put up BIG numbers...


Keep up the good work and I look forward to using your TT kit in the future.

Now I see what everyone is referring too, I thought someone actually posted a before and after dyno graph showing a 37 rwhp gain. The numbers in this thread:

http://www.the370z.com/engine-drivet...html#post54283

Are not a valid comparison of gains and should not be used as such. I am sorry but there is just no way the car would gain that much power from a cat-back exhaust and high flow cats. I understand a lot of member in this community are new to the modified car scene, but these types of gains are just impossible and laughable to many.

I can understand the confusion though, no hard feelings :D

I think you will be very impressed with our twin turbo system, we are looking forward to earning your business!

bullitt5897 04-10-2009 08:43 AM

George,
Do you have some final production pictures of the exhaust? What are our options for the Tips of the exhaust.

Also, Ben and I knew we couldnt compare each car exactly for actual gains. However, for guesstimations even if you were to give Ben's car a margin of error of 10 more rwhp in stock form over mine he still made 27rwhp over stock with just HFC and Catback. I believe your products could do the same as well. All this is speculation of course and its just food for thought on how capable these engines are...

let me know about the options on the exhaust.

thanks,
Mike

George@GTM 04-10-2009 03:54 PM

Hi Mike,

We are still waiting on the final production versions to arrive. Once those come in I will take pictures of the different available muffler options (stacked or angled) and different available tips. There will be standard polished tips and Ti tips.

I understand your point of view, but the fact is the margin could be more than 10rwhp, and it is impossible to compare. I just would hate for people to think they can gain 37rwhp from a cat-back exhaust with HFC when this is in fact impossible.

bullitt5897 04-10-2009 04:36 PM
