Cant wait how much they sell that for! Pricey (probably) but kudos to awe to have gone the whole way for total results!

 

Sounds good, but I'm a little bit dissapointed in the HP gain, was hoping for more. The torque is impressive, but since it is at a relative low rpm, I'm not sure if you would feel it on the track, just on the street. From all the ones that I've heard so far, sound wise (this is of course only IMO), the GMC ones sound the best, Sharkwerks and Awe share second place, and FVD in last place. Nothing wrong with FVD, just a little too raspy for me. (None of the sounds I've heard in person, I've shared the track with over 10 different 997 GT3's but all still had stock excausts.)

For the price difference between a full system (have no idea what it will cost, but it has to be at least double of a "center muffler replacement) and either GMC or Sharkwerks, I'm not sure if the Awe System will be worth it to me personally.

How much extra HP does the Cargrafic full system put out, and what will be the price difference between Awe and Cargrafic (both great companies)

I hear you eric; but as i look at awe's dynos id hate putting a center exhaust that takes away power for sound

 

I'm with you, there's no way I will give up power for sound, I just unplug the exhaust modulewhen I go to the track. The only real reason why I've looked at them was the weight loss, the sound was a nice benefit. $2K is still a lot of money to loose 16lbs.

 

The most impressive thing about this is the honesty and full disclosure of the testing and results. AWE doesn't try to dazzle people with smoke and BS. Unfortunately that is something rare in the marketplace.

 

As far as I know, GMG and Sharkwerks don't lose any power. Or am I mistaken?

 

The dyno graphs don't show replacement center exhaust. I wonder why?

 

In fact they do They show center exhaust removal (straight pipes from both side exhausts) and they show straight pipe off headers in 2 inches and 3 inches; removal of center muffler with straight pipes lost 7whp 7wtq from 1000rpm to 8400rpm, straight pipe off header lost 20whp from low end and lost (never made an hp) till cutoff!!!
Stock exhaust is the only way!!!or pay big price for awe or cargraphic

 

Not really.
One says fender well muffler delete and the others say 2 and 3" straight pipes off the headers. I don't read anything about the center muffler being the only thing deleted...

 

Hey Eric,
Not that you need any more HP, but if you must know, the Cargraphic exhaust (Kit 5 an6) save 17.5 Kg (38.5 lb) and increase power by 17 KW/23 HP and torque by 17NM vs. stock. I suspect that the 200 cell trimetal cats are the main contributors to HP and torque, and the best part is that it all occurs from 5000 to 8400 RPM. I have not asked but I would not be surprised at a 5K plus price tag. Cheers,
Manny

 

There is no AWE dyno graph showing a rear section muffler delete only. The dyno losses were from all muffler delete with straight pipes and with the fender well mufflers deleted (which I assume means the center section remained). Plus, I believe Sharkwerks and GMG both stated their dynos did not result in any loss with their systems. Maybe they can comment to clarify.

 

Off Topic,

Does cargraphics have a website? If so can someone post a link.

 

Yes their website is: http://www.cargraphic.com/

 

Thanks, I feel like an idiot! Funny how I tried to find it through a google search but couldn't.

 

Hey guys just wanted to clarify any confusion about our system. We do not claim any power gains although we could. I am just not into the "claimed"power some tuners represent.

Our system looses no power - but it did loose weight and the sound is intoxicating.. Simply by design. It is different than Sharky's set up although there is nothing wrong with his either.

When we tested our system it made 3hp on regular 91 octane fuel and when we ran the 100 octane it made 5hp. I think the added power is related to the fuel more than anything. In fact I am pretty sure if you dyno'd a stock car on pump versus 100 octane it would make more power with no modifications.
In racing saving weight is just as important as making power. Any driver will tell you they want a lightweight car that handles and ultimate power while good isnt everything.. That's why we started with removing the boat anchor hanging off the back of the engine LOL

Its all the reason why we dont even make a claim that our system makes more power.
If you carefully look at our design it is more than just some straight pipes welded together.

I know AWE has spent a lot of time developing the system and I think the power gains are represented fairly.

I am not sure what the price tag will be but as with any complete system that include a complex header design it wont be in-expensive to manufacture.

We work closely with some of the engine builders at Porsche Motorsport NA (which is located across the street from our shop no more than 20 yards away) Often times I will bring something over to get there opinion on what works and what doesnt. And often times I get a grin and a chuckle.


Hope that helps!
