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.

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. |
Are the exhaust tips fighting each other?:laughabove:
its DUAL exhaust. |

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

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

I've owned both -- from my experience, the stock C6 exhaust is more quiet than the stock C5 Camaro exhaust. Visit the C6 (Corvette) forum and read all the complaints about how dead quiet the C6 exhaust is. |

Tose bad bends dont seem as importantant because the exhaust is moving differently n the large diameter pipe co pared to the narrow diameter of the header primaries. The mufflers on the LS3 are designed like most typical absorption style mufflers with perforated tube. I have not seen a cut away of the corvette muffler to compare to the SS.

The stock exhaust does not restrict flow or performance until you get up to around 680rwhp. This was documented by Ted of JRE about 3 years ago if you care to search back that far.
SOooo... if you buy an aftermarker catback, axleback or get the optional NPP exhuast, do it for the sound. That's all that is going to change. Aftermarket manufacturers have reported BS gains ever since the first aftermarket was released. |
This thread is awesome!! lol :laugh:

This is total bullcrap! A 3" X pipe exhuast will make power over the stock exhaust in propbably even a mild bolton car. Explain why my car picked up 2mph with nothing but swaping 1 chamber flowmasters to 3" glasspacks! Dont bother saying weather, because it was in simular conditions and I noticed an increas in performance right away! Plain and simple, they flow better... the stock exhaust is not going to match a good aftermarket systeme, I dont care what test say. |

All that matters is what happens at the track...and every car is different. Dont go by what dyno test on one car show and take it as fact. Its just idea of what the out come could be on your car, thats why cars with the same parts will respond different. I just talked with a guy not long ago who picked up 15 at the wheels with his cutouts open, he was running the stock cat back with aftermarket mufflers. This was in a cammed car... so according to you, this car would not see a gain by switching out the stock exhaust to a full 3" aftermarket setup :sm0:

GM just didn't choose to update their performance specs for the 1LE from the standard SS. Likely due to the fact that 1LE is performance option on an SS rather than a separate model.
There should be no question that 1LE options will increase power and enchance performance over a base SS. |
I just love how some around here say 6 HP is no big deal and you will never feel it. Granted I would not feel it, but if you add a CAI and VMAX TB each of those add a little but when you add them up they mean maybe 20-25 more HP and Torque to the back wheels.
In my mind every litte gain is worth trying to get and gets you closer to a 5.0 off the line. |

In my local chevy dealership, I was observing a Corvette Grand Sport with the dual exhaust and it really look great, but then I saw also there, the dual exhaust in the Camaro, and it looks ugly, it looks very different, I prefer the looks of the exhaust on the regular Camaro or better yet with the ground effects diffuser or havoc rear diffuser
