I'm curious, can you please provide your baseline dyno info? Thx.
I didnt post a thread, but I gained nothing as well. The before dyno was done 2hrs before the after. I really know my way around a dyno. I have a feeling my next dyno(well over 2k miles later)will show good gains. At least I hope so, because it feels faster. I have headers and an intake to install after the new baseline. Then Dyno again.
OP,
I got used to all the sounds it makes and I thoroughly enjoy it now. Its not quiet, its good loud. I hear the Borla is over all quieter-less aggressive sounding.

It is the quietest full dual exhaust option we have for under 2k. Its a high quality exhaust at a fair price. Comparable systems are really Borla, ISS & Royal mufflers ranging from 1-4k, I bet you if you read back you will find 30 treads in the past 6 months similar to your own. The ratio of happy vs unhappy isx50 & isF Joe Z exhaust owners is just silly in favor of the system. My car gained on 59whp from sikky headers and a PTS, il give sikky 40 of that but Joe gets the rest. Love mine and track it on the regular...
After you disconnect the battery it takes about 5 drive cycles with WOT pulls for the car to adjust to the mods completely, you get about half the power upon install then the rest threw the ECM adjustments.

Seriously I drive over 75 miles a day and can easily have a conference call on the Bluetooth..
Or great conversation with people in the car.
The sound we developed on the system still keeps that rich luxury feel when you're driving normal, but at WOT you get that true performance sound that our unique V-8 creates.
I get people who ask me to make it louder and I get people who want it quieter.
Fact is for over 2 years we have made it one way and will continue to do so.
We can make it louder & obnoxious too, but drone will be there as a full time side effect.
Regards,
Joe Z

^^^ Not trying to be negative here but there were a few members reporting cabin drone @ 2K rpm UNDER LOAD.
In one of the posts I read you offered something for the muffler to fix it.
Bottom line is if there is no drone and and muffler is modified to reflect the stock functionality of the tips then I am all over it! I Am sure you can custom tweak it for me Joe!

Because it takes some time for these factory ECU's we have to relearn.
After every mod I do I disconnect the battery, pump the brakes to get all electrical out of the car. Connect battery, test to make sure the install went ok then after 3 weeks I'll go and do a dyno if my interests peak me enough.

Given the same exact values in the ECU with a restrictive exhaust and the same exact values with a freer-flowing exhaust, the latter is going to make more power, unless the exhaust wasn't a restriction to begin with. Not that I'm saying that's the case here. Just talking hypothetically.
