Competition ZTek Porsche 996 F1 Sport Exhaust System

 

I just looked at the website. that system looks pretty good and good pricing too. Actually they say Our own dyno results prove increases of 22.5hp and 17.5 ft/lbs torque on a stock 996, with just the Muffler swap.

Customers dyno's have seen increase 25.5hp and 22.5 ft/lb torque on a stock 996, with the ZTek Super Sport Mufflers and Headers.

Customers dyno's have seen increase 30.5hp and 29.5 ft/lb torque on a stock 996, with the ZTek Super Sport Mufflers, Headers, and Sport Cats.

If thats right, and they sound good, I might be getting those instead of supersprint mufflers. 2500 for a cat back exhaust on a 911 is great, especially given dyno proven results as high as those.

 

I had the Ztek exhaust on my last C2 I liked them. Get the headers too. You will enjoy the sound!

 

I have the headers and the exhaust. Lie them a lot, great sound, great price! They fit well, no problem easy install.

 

would you suggest going for the cats in addition to the exhaust and headers? i think its such a good deal nopt to get all three components. are hp and tq claims accurate? do you feel a good difference? they are saying 25+ hp with headers and exhaust, do u find this to be accurate by the seat of the pants dyno? has any done a baseline and then after mod dyno? if so please post results and/or comments.

 

John- Thanks for the input I thought the pricing looked good I just wanted to get some feed back from the board first. I just bought a set of Neil Ortons headers don't have them on yet thought I would do the headers and mufflers all at the same time. I think I will soak the header bolts for week or more in liquid wrench before I try to remove them. The mufflers I have taken off before and that was a snap I am hoping to loose some weight with these also the factory units are HEAVY!

 

Don't go with the cat bypass unless you have forced induction. NA cars loosee too much back pressure and you will lose low end grunt.

 

what is the web address?

can you post the dyno charts here?

 

are you really claiming 17HP for mufflers alone? your website even goes so far as to claim 22 HP for a Ztek muffler swap.....

if we could see you i'm quite sure your pants would be on fire

 

so you'd offer a full refund for anyone that doesn't pick up 22HP from the muffler swap?

 

What happened to the ZteK posts???? Did you scare them off DeputyDog95. Did someone delete the postings?

 

Maybe they were deleted because they arent an official sponsor.

 

they're not a sponnsor so he probably got dumped off here..... i was wondering how long it would take before one of the moderators caught it.

seems like a decent product for the money, but i wish they would drop the riddiculous claims.

 

not a sponsor, it is unfair for the paying sponsors...

 

somehow I must have deleted my post. Here is their web site if you any questions. http://www.zerotek.net/. I'd like to see more dyno's though, especally with their full system.
