anybody tried ztek exhaust?
I searched and found nothing about ztek exhaust for 993's here on rennlist. Since they are now a site sponsor, I thought I'd ask if anyone has any experience with their product in 993's.
here's a link.

Hmmmmmmmmmmmmm...
From their web site we see, "Our own dyno results prove increases of 22.5hp and 17.5 ft/lbs torque on a stock 996, [B]and power increases will be very similar for the 993, with just the Muffler swap.[/B]" I'd like to see that dyno sheet....the 996 exhaust headers look very well designed, stock. Because the 996 gets their heat from the water system, they don't need heater boxes. Their exhaust headers look very racey from the factory.
They add, "Although on a stock car they work great to increase horsepower and torque through the entire power band, it is HIGHLY recommended to pair these mufflers with ZTek Headers for even more significant gains in power and an even more unique sports car sound." Please...if I put headers on a 993 I lose my heat.
They may be great mufflers...I just don't know anyone who has them. I don't like their inference that because they got 22.5 HP and 17.5 ft. lbs of torque on a
996...why should we expect this on a 993?
If I were you'd I'd be asking some questions on the incremental HP and torque...they may very well have the answers.
On my end, I have Robin Sun's RSR mufflers. I have also used Joe Fabiani's FabSpeed SuperCups. I have no first hand experience with our new sponsor. I am also coordinating a Fabspeed Group Buy at this moment..although if you prefer ZeroTek...buy them.

Martin,
I am not saying that I prefer them, just that I found them on ebay, did a search here and found that they are a new sponsor. Just thought I'd ask to see if anyone has tried them out on rennlist since they are indeed a sponsor.
I did read the same referrences to the 996 and found it funny that they have a video of a 996 and not a 993.

Sounds like a load of something sounding like bullocks!
Lance, please provide the justification for your power claims as most other exhaust swaps, at best, struggle to maintain the current power and not to add to it?
I'm runing Cargraphic sports cats and sports mufflers and I would be struggling to find an extra 20hp.
Thanks and regards,
David

The 20 so hp increase would be a "MAX" increase usually around 4000-5500 rpms, although total top end hp is also increased by 7-12 hp with our systems, with no remapping.
But we did find out that reading wideband 02's during each dyno, showed that the stock ecu fuel map is quite rich with the increased flow and leaning out in the mid/high range can squeeze a few more ponies out, (around 5-15 more hp).
Careful anaysis of dyno printouts can show you that the most noticable instant increases in power and torque occur in the mid-range rpm's which is most important for street driven cars. More specifically we custom design each exhaust, matching pipe length and diameter along with muffler size, to each engine and application, for power and sound, unlike other "cookie-cutter" systems that just create noise. Result is a sound that is unique and doesn't drone.
When writing the descriptions, we use the norm by advestising the max increases and not diving into all the details, but if you want any more in depth explainations on how our systems increase power, and why our systems are different from our competitors and stock, you can contact me direct pm or phone.
PS- We are in the process of aquiring new ecu tuning equipement, and partnering up with a tuner in europe. And we will be be offering ecu upgrades that will pair with our exhaust systems, for a more complete tuning experience.

These guys are jiggy...
They want evidence. If it were me, I'd dyno the same 993 before and after, the same day....put the stock 993 on the dyno...crank out the numbers. Bolt up the new exhaust and fire it up again.
Once they see the numbers, then you will have earned muffler "street cred".
