Does the duel exhaust add 6hp like it does on the vette?
 
Im wondering if the duel exhaust adds 6hp and 4ft pounds of tourqe as it does on the corvette. And if it does why areent they advertizing it?:iono:

It doesn't. And who cares? You'll never feel 6hp.

2013 camaro brochoure specs for 0-60 for the 1le is listed as 4.7 sec same as 2ss ls3, and anyone with a half of a brain knows with higher rear end ratio of 3.91 , 0-60 has to be quicker than 4.7 as listed by chevy. In fact motortrend test of the 1le 0-60 time was 4.3. So just because chevy says theres no difference in hp between the duel exhaust and stock exhaust they might be wrong.

Anyone with half a brain knows that 0-60 times are meaningless. There is no standard by which those tests are run.

And again, it doesn't matter. 6hp doesn't make a lick of goddamned difference. A race between equal drivers between an NPP Vette and a non-NPP Vette will come down to conditions.

I agree that its not enough to feel in the seat of the pants, but why wouldn't it make additional horsepower over the regular exhaust? I suspect that Chevy isn't claiming it because they haven't gotten around to certifying it.

I'll be interested to see what happens when somone puts an NPP on a dyno.

No it does not add hp or torque to the Camaro.

It has been shown on numerous dynos by different shops that any changes from the cats back on the Camaro will result in zero gains. The Camaros exhaust is already free flowing which explains why this is so.

Geez, the guy asks a simple question and he gets lambasted. "Anyone with half a brain...". It was a legitimate question. :)

Some (you know who you are) just can't help themselves. They just have to act like my ex wife. Good riddance.

Well you might have 3.91 gears but you have a different trans in the car. the close ratio trans is different than in the SS. Meant to keep your engine in the sweet spot through the gears. It might be interesting. Maybe another drivers race type of thing

Are you saying that aftermarket catback exhausts also result in zero gains or just the NPP exhaust?

Yes after market catback systems offer 0 gains. Purely enhanced sound.
