about how much will this system retail for? what are the horsepower gains with the 2.5 inch piping on your vehicle. with the 2.5 inch piping did you feel that you lost any horsepower/torque in the low end? top end?

just a few questions pertaining the new system

Jordan

 

Retails for 399 I do believe.

I am not sure what dyno runs they did on the car, I was no at the shop when they did the dyno's, from what I am aware of ... is they stated a 14hp increase over NO exhuast system. so I am not sure how that compares to stock. (I would asume, which I hate to do.... 7-10hp gains)

No I do not feel I have lost ANY thing.. It has a much stronger pull from 3500rpm all the way to the redline. I can even bark the tires in 3rd, so no I would not think I have lost any torque or power on the low end, if I have it may be below 3000 rpm.... which my car rarely see's.

 

I have the saleen kit, and as you know it needs a center exhaust, If a muffler shop were to bent the exhaust pipe and add a dual tip, would it change the HP gains? I dont know anything about exhaust systems. but I allready plan on getting it (you convinced me)

id just like to know.

 

Is the exhaust for sale from them now? How would you rate the ATR system in terms of noise volume? Did they use a resonator on your car?

Vision: Depending on how the bend is completed and how quick of a turn it is, yes it can effect the output some. as for as a dual tip on the tail piece no.... Plus one for ATR on this option. the muffler is located before the rear arms so a custom tail piece could be done easily with thier system.

BLOWNSTANG
The base system should be currently available for the ZX3.
As for as the volume issue, I would say a good middle to loud range No they use no resonator on my system. not saying they wont offer one. they stated they would be offering two different sound options. I am not sure how they are going to do this currently. On the sound volume issue due to the deepness of the tone it doen not seem to be as load as it may really be.

It is about as loud as a SVT mustang with just about as deep of tone, just sounds a bit tighter.

 

Vision, just think about it. The exhaust wants to flow out as fast as possible in as straight a line as possible. If you take a straight line and you make it split a fork in the road, obviously you'll see some losses. You could argue that you have 'more pipe' so its less restrictive, but ... well since everyone trusts what Borla says over some shmo like me

:
"A common misconception is that "bigger is better". Many enthusiasts, and manufacturers too, seem to feel that very large diameter pipes are the only way to go for muscle car performance, while we at BORLA have found for street use, big pipes just take energy out of the exhaust, both by slowing down exhaust gas velocity and by cooling off the gases. While exhaust may leave the port at 1500 degrees or more, at the tailpipe it’s down to 150 degrees -- a sign energy has been lost. Velocity and uninterrupted flow are the real performance-making factors.

Furthermore, it is the low frequency range that has energy (the sound you can feel inside the car); big pipes increase the low frequencies, making an uncomfortable roaring or droning sound. A BORLA exhaust system, on the other hand, is designed for less restriction, keeping the velocity and frequency high so the main sound is behind the tailpipe." -copied from www.borla.com

Now you could argue, well why do most of the high performance OEM muscle cars choose dual exhausts? The 'Stang, for example, uses two 2.25" pipes, but I think that was mostly for packaging reasons. The cylinders are already in a V-configuration and to combine that into one large 4" pipe would be kinda big to snake to the back of the car and probably less of a straight line than the X-exhausts. If you did a dual split like that, it would really just be for looks. If done right, you probably wouldn't lose much to notice though.

Just about any good aftermarket exhaust is going to be a small improvement on stock, because they use more free flowing performance mufflers (which makes them louder which can either be a good or bad thing).

But stock should be a performance increase over NO exhaust... so that doesn't really make sense and sounds pretty misleading to me. No exhaust is worse than going with too big of an exhaust... now you have no scavenging at all and your exhaust pushing against 14.7PSI of atmospheric pressure (not to mention being too loud and possibly being a health hazzard with exhaust fumes coming out right there instead of behind you hehehe).

Edit: Just refreshed to see your post. Are you sure the resonator isn't just included in part of the muffler? (a small chamber perhaps)

I agree with you Duncman...

And yes the Borla information has alot of merit.

and the deal about HP rating over NO exhaust I see a bit wierd myself. I am going to ask them to put the stock system back on and run a dyno then use the Production model and do the same.

But lets look at a few other reason for larger pipe. IF you are looking to get more than 50+ hp out of the motor you need to look at the POSSIBILITIES of use a bigger system. now this will not always be a good thing to do.

increase air flow by more than just a modest amount you will start to reach the limits of a free flow exhuast and back pressure will limit how much you can get out of the motor.

When we flow tested the 2-1/2" system it will free flow based on the CF of air up to 250 hp. based on the engine air / fuel mixture at that level the engine is pushing more air than the system can manage.

The other rules also apply using forced induction. you will need a larger system to handle the increased air pressure - (flow).

ATR is using the larger pipe dia. to meet the the markets needs for the SC and turbo systems. as well if you have had head work and high compression piston installed. you need to look into a bench flow test to see how much air needs to flow out the exhaust.

Bench flow test are very benifical in determining what size best meet a modified engine.

If you are not going to push more than 180 hp..... smaller is much better.

so at this point my car is actually losing a few HP than what it could have... But ATR is looking at bench flow numbers for the system NOT HP.

Chris's Car with all he has done to the motor would see much better results than my car.

Have a Merry Christmas and a Safe holiday season.

I have seen SCZX3 car with the system on it, and it is good! I veiwed the shop and grounds at ATR and met with George, good people and they know exactly what they are doing. The quality of work there is outstanding. Custom work is their specialty. I hope they can get my 3" system done and on it's way soon!

OK, SCZX3,
Christmas $$=New Exhaust.
I have the k&n FIPK, and AF/X UDP. I', not going to do any forced induction or internal work for a long while. From what I understand, 2.25" tubing is appropriate for me...???
I Auto-X, so torque is very important for coming out of low-speed/tight corners.
I have had my mind set on Bosal for sound/quality/price/performance/attitude-in-posts here, but your posts HAVE caught my attention.
What I'd REALLY like, is Pictures, Dyno on 2.25" system(otherwise-stock), availability of 2.25" System, and if possible, a sound-clip. If they want to promote their new product to our market, and win business, these should be readily obtainable, esp. at the behest of someone in touch w/ their audience, who has a test-car.
I don't have much $$, but I have enough for either, as their prices are very close.
Not to be anything but inquisitive, but , why should I buy this system instead of Bosal???
Sell me.
BTW, what, roughly, should I expect to pay for shipping either exhaust system to Knoxville, TN???
Thanks for ALL Available Info...

 

Becouse the quality is that good, and it looks like it was made for YOUR car npot everyone else's.

 

I have a picture of this system and i will put it on here as soon as I can figure out how to do so, as I am a "Big Dummy" when it comes to this sort of thing. The system is for sale and is retailing for $399. More info to follow. They know we have a large interest in this and they also have a cold air intake if I am not mistaken.
More to follow.

zac

Michael, why dont you just drive to the plant, that is what I am planning to do.

vision, you have mail.

 

Pricing? Pictures? Dyno Charts??
ATR locations? Website? SoundClip?
Ok I think I covered all my questions......
looking for something to replace my MBRP.........

pricing: so far $399
pictures: waiting to be posted
dyno charts: same as above
Location: Fair Play, SC only
website: ATR (last time I checked, no info. on site)
sounclip: none as of yet

 

So does this system actually exist? Is it just a "pipe-dream"?(pun intended) I need 2.25" tubing, and would like to get exhaust on the car ASAP, before I blow my Christmas $$, and before the Auto-X season gets started for '02. Will it happen w/ this co., or should I just go ahead w/ Bosal or MBRP?
Zac,
I Love a good road-trip, but I don't think I could get time to go to S.C. during business hours. I appreciate anything you may have learned and can pass on.
Thanx,

LOL.... Pipe dream.... good one

No the system is available. If you like I can give Sherrie a call tomorrow for you and ask about a 2-1/4" system.

If they can get it quickly do you have someone in Knoxville to put it on or would you want to do it yourself?

 

Bosal!

 

Gotcha BANDIT!!! e-mail me that sound-clip...

SCZX3, I would be doing my own install.(W/my Dad's Help 'n' Tools).
YES, I want to know about 2.25" availability,
YES, I want a Good sound-clip,
YES, I need #'s on a 2.25" system vs. stock exhaust.(Bosal has these #'s avail., time to step up to the plate and swing...)
I want a Fair Fight, But I wanna spend my $$ w/ an INFORMED opinion.
Thank You.

 

e-mail me, I could post it for ya!!

 

Whooooaaa..... let set this straight..

I am not in a fight..nor will I be. Everyone needs to get what they want for thier car. not one item will fit everyone needs. What i can give is information on the ATR system until they have all thier marketing items together.

I will offer any information you may need. I am just giving information on a new system available for focus owners. If you need detail on what you need your best best would be to contact Sherrie or George at ATR.

I am willing to help, but I am not an employee of ATR. I am letting them use my car to develope new items they want to market.

So keep the questions in the response of what you what to know ABOUT the system. I am not knocking any other item on the market. There are many good systems available for the car and a few I would not shake a stick at.

If you want me to help then ask exactly what you need help with.

Thanks,

Hope everyone had a VERY MERRY CHRISTMAS...

 

Yeah the Grand National Frame in the front is awesome...

They are not a young company at all. they have been doing systems, not just exhuast, for more than 20 years.

They have specialized in the GN, Mustang SVO, Cyclone, Typhoon.... Etc..

They have not done any Compacts until now. They do have a web page... I just cant remember the address... sorry.

 

If you click on ATR in my post above it will take you to their site. They've been doing an exhaust for the Eclipse for a while now and just released systems for the WRX & VW Golf.

 

ATR is a great company
so is MBRP but i was disappointed in the sound it created, and it rusting at all the joints, and my bolts....... for 479 I exspected more

just would like pictures of the system and a sound clip...........what it's being made of etc...

 

I cant seem to open the file.... on any computer??
ill keep trying though
