Installed mine about 150 miles ago, bought from Dan (Thanks for the great service!)
Sound has changed a bit but they are not much louder than stock. They are lighter in weight, and the tone is a bit lower than stock.

Picked up some unpleasant interior cabin resonant vibration at around 950 rpm (cold idle). That prompted me to dismantle my passenger door and tighten up a couple of loose screws on the Bose speaker box that were rattling with the resonant frequency.

My (multiple) dyno tests show 0 rwhp / tq / curve gain over the stock exhaust after a brief break-in period.

but they sure are pretty

 

Here are some links to other sound clips and before and after tests we have done.

And here is some info on our dyno -

Alpinam5 you can send me a PM. I will be back in the country on Monday.

 

in the fourth link you have a write-up stating almost 30rwhp from adding the KN and AP. That is awesome. After doing my (multiple) dyno tests and allowing for ECM adjustment / relearning, I did not gain a single rwhp.

What dyno settings were used? I'm off to the dyno again today. My pcar stock was pushing 253.5 rwhp and after adding both parts was pushing same.

 

exactly, stock was at 222rwhp. with intake and exhaust, 249rwhp. Dyno settings are not important as you are not using a mustang dyno i believe? You are more then welcome to bring the car to us with the stock exhaust, have it dynoed and then we will put the other one on for free again and redyno showing you the HP. Have the shop contact us and we can discuss how they are conducting their tests. The bottomline is the product makes HP after numerous tests in different cars, climates, and settings. You are happy with it. But coming out and saying the exhaust makes 0 hp is incorrect and I have to stand behind the truth of my product.

 

Hmm- drive from West LA to AZ. Sounds like fun but I don't think I would have the time, appreciate the offer though- Would probably be cool to check out your shop.

Dan, come on- I'm not across the board knocking the AP product. If you read my posts I specifically say on MY car it shows 0 rwhp gains, and stating across the board gains on all cars is IMO subjective.
So you can refute me on what I see on MY car, but I don't know what to say other than 'the dyno doesn't lie'.
If it shows gains on other cars, that is super. Especially if the 996 tested in stock form was rolling 222rwhp- That's kinda low numbers for a 3.6l NA isn't it?

My primary reason for purchase was the sound factor and shave off some sprung weight, which I'm pleased with. Your service is fabulous. Pricing was the best around.
Can we end this and move on, please?

 

The test was on a 3.4L btw and Mustang dyno read lower then other dyno. Not the number but the difference that matters. Not saying its you, its the shop running the tests. I am glad you are pleased and that is all that matters. Moving on!
