You wanted proof, here it is... Everybody loves sweet thunders and as do I, but only for sound, but they DO HURT POWER BY ALOT. I now have proof. Same mods, except an added pulley. On a mustang dyno, my car just put down 3 more horsepower than my last car did on a regular dyno. On this car, I have a ORY, cut-out, and magnaflow as opossed to sweet thunder true duals. There is your proof. BTW, my TA put down 383 through a 12 bolt and steel driveshaft on a mustang dyno. I'm happy with how quite magnaflow is, and yet still flows superb.
I really don't know if I'd call that proof. Trying to compare 2 different cars (yet alone 2 different years) is one thing. Trying to do it on 2 different dynos is another. Finally with one being a dynojet and one being a mustang dyno, there's really no way to tell what the hell is going on there since no one can definitively tell you how great the power differences are between the two.
bahaha

Different cars, different dynos, more then likely different weather conditions, different software, etc.

and even if you are correct im sure most people arent going to go limb over a ledge for swaping truduals to c/b. Its 3 hp its a small amount, yet it is still hp.

But, like I originally said, it's like comparing apples and oranges. The only way you could see some type of "proof" is to switch the systems out on the same car on the same day on the same dyno.

I understand it is two different cars, but 9 times out of ten, an ls1 with the same stuff is usually within 10 horsepower. Secondly, I didn't think SAE factored in weather conditions, I thought they were factored out. Lets says weather did matter. How about this, my camaro was dynoed in December with that ****. This was today and it was hot and muggy. Back during that last dyno, it was about 50-60 degrees and not muggy at all. HPE told me their mustang dyno made about 20 or so horsepower less than the regular dyno. I'm sorry, but the difference is too big, especially pulling an extra 400 rpm. Maybe it is a mute point, maybe not.

What we all need is a guinea pig who's swapping from say, a Magnaflow catback, to TDs with Sweet Thunders. Do a dyno before the swap, and again after the swap, preferably on the same day to keep weather out of the mix.
I'd agree that Thunders hurt the performance of your car, but if you're running dual 2.5" pipes, you're already going overkill unless you're putting down 450 whp.
