Do you know where that data is? Thinking about switching to the atlp v2 from my xlr8 v1 for extra ground clearance but don't want to lose performance ( both keep my third cat cuz of California smog)

Perhaps I used the wrong word, but regardless, a supercharged application will benefit disproportionately from a larger exhaust. I understand what you are going for, in showing the comparison between different pipes though.
I disagree that N/A numbers would not be relevant. Contrary, I believe that most, if not ALL aftermarket vendors subscribe to the 'you can go too big' on exhaust and I disagree, as well as the numbers. I've yet to see an application where a larger pipe lost power. LS1 owners have learned that 1 7/8 headers gain over 1 3/4 all day long, even in mild applications.
I'm not looking for a full comparison of all pipes on an N/A, but I'd like to see a stock TL with one of these. I think the numbers would be quite surprising.

What I do say, again, is that while a 3" pipe might gain 12 hp on a blown car, and 8 on an NA one, do we not value the gain either way? The powerband does not change...the relative gains are different from one pipe to the next. So our charts will not focus on power numbers. We are looking for you to focus on the shape of the graphs to decide which pipe is for you.
To get the data we needed, it had to be exported as a text file. We dumped them into Excel to manipulate the graphs as needed. So I am messing with that now getting something presentable. As much as the Dynamax is an awesome dyno, the display software sucks.

I am looking for the best exhaust for my 94 tl automatic, I want to get the full atop exhaust with quad mufflers but I wamt to make sure I am able to pass inspection and what kind of coil overs will I need after I get this, and what is the difference between stage 1 2 3

Marcus, you said this was a dyanmax dyno. Was this done at Church Automotive? I thought they had a dynapack - the one that bolts to the hubs.
If so, I'd like to see kingkong_dav's numbers on a dynojet just for comparison. Typically the dynapack reads lower HP cars lower than a dynojet. In the 420+ HP range they are very close. I'd be more impressed with 350whp out of his car than 320. Plus, dynojet numbers are the industry standard regardless of what anyone's feeling about them may be. There are probably 5 dynojets to every 1 other kind out there, so that's what people know and see.

Car feels quick. Exhaust note has more rumble. Power is there from 4500 to 6900. Passing up cars on the freeways have been easier to do. The piping doesn't bottom out at all with aspec springs. Engine sounds mean. I can spin out the tires with the added low end. Thank u marcus

My car has been a beast lately. Same hbp no meth w 3 inch piping. It moves quickly and sometimes wen I wot it feels " alarming" just by adding the atlp I notice the car moves more than before. As for the dyno charts idk wats going on.. I think Marcus is on vacay
