That's good, but looks like the power and torque gain is only between 2000 and 3000 rpm. What's the use? Who actually drives between 2000 & 3000?
Call me crazy - but I do - every day . Significant power boost or not, the exhaust is lighter, isn't more restrictive regarding flow and looks nice. Plus if there's no drone - we're moving in the right direction IMHO. Once again, thanks vendors and early buyers / testers of these products.

I'm waiting for the "Works", and see which one really does the best. I believe that for $400 you should get more bang for the buck. Time will tell us which one is the winner!

Same here.. between 2000 and 3500 rpms is where 90% of my city driving is and that's where I wanted an improvement. I really don't care about the top end because I never use it. This is the very reason I was totally sold on the original DTH exhaust and the same reason why I like this one.
And Willy, don't try to tell me there's no difference at all or it's an error... This is the 3rd or 4th dyno graph I've seen on various DTH systems and they're all consistant.
The point is, for less than $400.00, you improve the dog slow low-end stock performance to a more enjoyable ride.[/quote]
For $400, you get the exact same performance than the stock exhaust. the good news are:
1) You maintain the same HP/TQ,
2) Your new exhaust sounds much cooler,
3) Your new exhaust looks way better,
4) $400 gave you a 20 lbs lighter car.
The dyno clearly indicates that the so called "increase" from 2300 to 2500 rpm is just a statistical error.
There is NO WAY you may have + 20% torque/power over a 200 rpm range.
This "surge" is a fluke, period.
Say it looks good, say it sounds good: it is true.
But please do not say it brings more power, or torque, it is simply not true.
I still commend you for posting - in a low res video - the dyno chat. It shows you are certainly not dishonest.
Willy, with all of the positive feedback from people who have installed this exhaust, plus a company like Doug Thorley, with their reputation on the line. I seriously doubt they would post the dyno results on a public forum if they could not back them up with repeatable pulls. Just because YOU don't believe it, doesn't mean it not true.

W&B08,
This exhaust is well made, looks good and sounds very nice, and, for me, is a well spent $350.
I have no reason not to believe Doug Thorley's posted dyno chart, which clearly shows that this exhaust produces exactly the same torque as the factory one and not one lb/ft more.
Hum, of course I did not realize that some people might be confusing the torque curves (the upper ones) and the horsepower curves (the lower ones). The HP curves are a function of the TQ curves, hence their curves cross at 5252 rpm.

It's important to remember the dyno measures torque and rpm and then from these calculates horsepower.
Quote:
Horsepower = torque x rpm / 5252
Here's an interesting bit of trivia; below 5252 rpm any engine's torque number will always be higher than its horsepower number, and above 5252 rpm any engine's horsepower number will always be higher than its torque number. At 5252 rpm the horsepower and torque numbers will be exactly the same.

You are incorrect. Doug Thorley has proven with accurate dyno run the hp and torque performance gains.
2) Your new exhaust sounds much cooler,
3) Your new exhaust looks way better,
4) $400 gave you a 20 lbs lighter car.
The dyno clearly indicates that the so called "increase" from 2300 to 2500 rpm is just a statistical error. The performance gains are from dead stop to mid-band rpm. Call DTH. Maybe they can teach you what all the mmebrs have been unable to.

You have me confused with someone else. I did not post videos.
