Dynos...??
Just curious but I see we have a stickied post for the sound clips and even pics...but how come we don't have one with HP and TQ gains?? Wouldn't that, other than sounds, be a motivating factor of buying a particular exhaust?
Just my $.02

If there are enough people with the same exhaust we can form a general idea of the increase ( or decrease) of HP and TQ for each exhaust.

The biggest problem would be if someone did a dyno when they first got the car and then 6 months later get a dyno after an install then with temperature playing a factor could throw the numbers off alittle. But you would still get some kind of generalization of the performance to be expected if there are enough people to submit dyno's of the car after an install.

I can understand how some people will say that it won't matter because of x,y,z. But if we get enough people to get dynos we can make a pretty good database on which exhausts are worth the money and which ones aren't.
I for one don't want to buy an exhaust on the sounds alone but wouldn't like to get a good performance increase along with the money spent on an exhaust.
What good is it to be loud but can't back it up???

I was interested in possibly seeing one due to the bassani exhaust stating the TQ gains. I wonder what other exhausts were putting down on a dyno that are somewhat comparable to the design.

Ages ago there were a few "exhaust shootout" articles written up in some mags. SportZ mag or something had the best one with dynos and stats.
Generally speaking though, besides going FI most Z mods provide minimal gains. The variance in dyno types alone can offset those #'s completely. Plus we now have 3 different VQ engine variants in the Z so things are going to be off based on that as well.

Do you still have the article, I remember reading it, it was a good read.

As for engine variants, thats simply another variable. As long as all the variables are known, and the changes in variables are minimized what is the concern?
