Hi,

If I currently have the CNT exhaust and would like to try FI for a change.
Would a 18" SS option be a noticeable difference? or should I go for a 12"?

Thanks.

I am not completely familiar with the CNT. I have never seen nor heard it in person. What I can tell you is that our 18" resonated version is our quietest inside and outside of the car. The 12" resonators will be somewhat louder all around. The resonator is nice to have to eliminate rasp and keep your exhaust note smooth and crisp. All depending on if you have test pipes or high flow cats and how loud you want it will help me make my recommendation.

If you have any questions or would like to place an order, please do not hesitate to call me directly.

Thank you, Tony

All depending on which specific options you would like to go with within the exhaust itself will determine what the cost will be. I will send you a pm with the options and pricing.

Thank you, Tony

anybody out there around the #670's range get their exhaust shipped out yet? so close yet so far! i can hardly wait to get mine

My #669 shipped Friday

Fast Intentions exhaust is here! (continued)
 

Get the carbon one!!:)

Does anyone know how loud this exhaust with 18" resonators is compared to the stock exhaust with AAM short tails? I have the S-line tails right now and while they are nice they are a bit loud and I want something a bit quieter.

Here is a question Tony. I'm still debating changing my exhaust. I have PPE headers, they rasp like crazy, and I have gotten it tamed. Assuming these rasp as bad as test pipes, would 12" resonators be enough (with or w/o HFC option), or would 18" resonators be the safer bet? I would call, but location is not very permitting (AFG COP).

Hmmm I haven't received mine and I am #662. No shipping notification.

D.

Your exhaust shipped back on 2/13. UPS is supposed to electronically email you with the tracking number. Roughly 33% of the time it does not happen. Your tracking number says that your exhaust will be delivered by the end of the day tomorrow.

I will pm you your tracking number now.

Thanks, Tony

Thank you Tony. I called and left a message as well but that answers my question. This time I did not recieve a notification from UPS so thought I would ask.

What's better than one Fast Intentions exhaust? Two Fast Intentions exhausts! :happydance:

good day tony. . . I pm'ed you a day ago, I don't know if I sent it right or not. if not I can ask you again..

. I just wanted to ask, where is your shop located? I am just trying to see what is best, weather to get them shipped to 92114 san diego, or drive to your shop and get them installed there. Also, do you charge for the installation?

I have the F.I. headers paired with the 18" resonators and SS cans and can say that it quiets down the potential rasp (even though I don't hear any). The cruising volume is a decent level and you don't have to talk Over the exhaust to someone else in the car. But when you want to get on it, it will be there to roar for you. :tup:

Their shop is in Simi Valley. About a 2.5 hour drive depending where in SD. Tony will have to chime in on the installation topic.

nice! i think im #673 or #674 so getting real close!

#666 arived today! Totally amazed at the superb handling that went into packaging the cats and catback. Thanks again Tony!http://img.tapatalk.com/d/13/02/20/u8umamut.jpg

Thanks for the update. I know if I opt for the HFC's, it will be quieter than w/o. So to compensate, I was thinking maybe 12" Appreciate the info. I was looking for a sound clip of 12" resonators and TP's, but maybe I suck and couldn't find it. They rasp similar to PPE's, so I thought it would be a good indicator.

Haven't visited here in awhile, having too much fun driving around with #641 - 18" res + CF cans!

Will post pics and details soon :)

:tup:

And now installed...

Good meeting you yesterday agrotech, what did your car end up making?

Glad it made it to you and is installed. Enjoy it and please call me if you have any questions.

Thanks, Tony

Well, I was disappointed at the gains initially. I dynoed 280 stock, and after intakes, hfc and catback, I was at 286. I got it tuned and am now at 299. I'm wondering if its the hfc or the takeda long tube intakes. I'm not so caught up on peak hp #s, but curious why my gains were so low. And as far as torque goes, I went from 234 to 246

You picked up almost 20 HP with easy bolt ons... that's not low gains lol

And a tune. Like I said, I was more disappointed before the tune... Which was needed anyway because my air fuel ratio was rich

Ah.

Well if you drove the crap out of it for a few weeks then re-dynoed, you'd be closer to your post-tune number because the ECU would have had time to adjust.

I never pay attention to or give any credence to "pre-tune" numbers because they don't really matter. A tune should (IMO) be automatic when you do anything beyond put a CBE or drop in filter on your car.

Again, my opinion (supported by your experience), so to each his own. Glad you were able to get it cleaned up, you'll probably pick up another couple WHP over the next few weeks as the ECU fine tunes as well.

Thats what I was thinking too. Love the sound though and the butt dyno definitely approves!

Look at my mods list and then come talk to me about disappointment. I base lined at 270.

First and foremost to properly gauge where you are the car needs to be tested in 5th gear. That is the 1:1 for both the 6MT & 7AT. If it is tested in 4th, the overall numbers will be down about 3-5%. I am not saying it was performed wrong but just double check.

That being said with the mods you have the numbers are low all depending on what type of dyno your car was tested on. Every dyno reads different and some are heart break dynos. Generally the Mustang and Dyno Dynamics dynos read the lowest. The Dynojet is the most commonly used in the industry and the numbers are pretty standard. The Dynapaks generally dyno high however are one of the best for tuning.

We have always performed our testing on a dynojet. On a 6MT we usually dyno right around 280 RWH & 235-240 RWT. Now without a tune and performed with many cars over the years, the average is right around 310-315 RWH & 255-258 RWT. This is all in STD mode on the dyno. These numbers I am giving you are for our CBE and HFC's with stock intakes.

All of this being said, once you put 150-200 miles on your car the ECU will have cycled through and adjusted for the new mods. You will feel a difference throughout the entire rpm band.

If you have any questions at all, please do not hesitate to call me directly.

Thank you, Tony

Thanks Tony. The numbers i provided were the STD readings from a dynojet. I thought the pull was supposed to be in 5th as well, but im pretty sure it was done in 4th.. I have an AT.

argotech,

Thanks for the feedback. Your drivetrain loss is also 5%-7% higher with the AT vs. the MT. Your overall numbers will be lower. It seems like your baseline was done in 5th and your current test was performed in 4th. If that is the case you do not have an "apples to apples" comparison.

Please keep me posted to what your finding are.

Thanks, Tony

It was 4th last time too.. last march. Evidently 4th is the gear to run in up to 125 mph for n/a cars... or so I'm told.

The overall mph is not the issue. 4th is not 1:1, it is 1.412:1 to be exact and for the 6MT it is 1.271:1

Thanks, Tony

Hey Tony did you get my PM?

7AT gear ratios:
1 - 4.924
2 - 3.194
3 - 2.043
4 - 1.412
5 - 1.000
6 - .862
7 - .771


just fyi for anyone who wants to know

My apologies for not getting back to you sooner. I just replied to it. Please call me with any questions that you may have.

Thank you, Tony

Thanks everyone. I resheduled a new dyno to be ran.

Badass.

Do some hard driving between now and then on the best fuel you can find. That'll be sure you run in the learned fuel data as well as can be done before you test again.

:tup:

Of course I wait 12 weeks and then the day it is supposed to be delivered we get over a foot of snow :ughdance:
