That would be a L99. LS3's typically dyno about 40whp more.

Excuse me for my ignorance, but could someone explain to me what the "Tri Y" design is and how is it supposed to be amazing on the LS motors. Im sure there might be a few others out there that might like to better understand this.

I just added a section to the thread below with information on the Tri-Y design.

Do you already have the headers?

I got in on the pre-order but after seeing the prices offered by some of the vendors here, the savings were negligible (around $20) since they're shipping them for free. Not sure if they're shipping out to the pre-order customers first but I'm thinking I should have just waited and bought from a vendor instead of spending that kind of money just to wait so long.

Great, should have waited a few more minutes before posting, received my UPS tracking number about two minutes ago.

Should arrive the same day as the CAI.

Sorry if this was covered elsewhere, but is this dyno run comparing stock exhaust manifolds and stock cats to the Pfadt long tubes with cats?

Hey guys remember during business hours always give Pfadt a call at the office. They monitor numerous forums like we do, so sometimes a phone call or email is faster than the forums!

I hear you, I phoned before posting and left a voice mail, then I remembered Utah switches to Mountain Daylight Savings, so there's an hour difference. Arizona stays on Mountain Standard year round, and that's a good thing because it cools down an hour earlier in the evening.

Be sure to post up some results and pic! We're excited to get even more feedback from our guys out there. Thanks for your order!

Here's a link to my original post Saturday, these are the real deal.

http://www.camaro5.com/forums/showpo...9&postcount=46

The instructions were very well written and straight forward, no issues installing and we had several social breaks. My friend has a lift and that makes the installation easier, more so the older you are.

I did a long ride on Friday, simply to get a good feel on an entirely stock L99. Did a short ride after the installation and noticed a seat of the pants performance gain all the way to red line. After church Sunday went for another long rural road drive with a friend, factory exhaust sound is different with the Pfadt headers and high flow cats. Used the paddles to short shift in town and actually chirped 3rd gear at about 37mph, that's low end torque!

There's an exhaust growl manually downshifting, especially 2->1, throttle response is instant.

Back to yesterday's drive, I'm getting better fuel mileage, but will know how much next fill up. I live at ~4400', so any increase in power is greatly appreciated.

Showed the installed headers to some friends, lots of positive feedback, including the exhaust sound. I will be keeping the factory cat back system for awhile longer and that will free up some $$$s for a stroker crank and rods etc.

No tune? Did you get a check engine light?

I retired to the very rural lifestyle, so it's a long drive to get a tune and the L99 responds better after the header install.

One of my concerns with the headers was the check engine light, but it's a non issue with this car, everything went well during the install w/o any issues. There are some close tolerances, but it's a good fit.
