Yea, definitely some variables.

End goal - Camaro SS runs same as stock NPP 436hp LS3 Corvette.

Could go with cutouts for those "special" moments.

I know just about everything when it comes to cars, except the mechanics lol
So my question is, how much more HP do you get when you install an aftermarket exhaust like Corsa?

Somewhere around 15-20rwhp?
What do you guys think?

I'm still working on the flip-switch supercharger like that of mad max...lol

15-20 is about right for it on its own. all aftermarket exhausts will net you about the same amount of hp. when you combo it with a CAI and less restrictive headers it might give you another 5 hp or so over a CAI on its own or the exhaust on its own.

[QUOTE=CamaroSpike23;232504]what transmission were you running?




With the 5.12 tci turbo400 with 4.56 I ran a denbar powerglide

Right around 500hp, which is what I want so I don't get blown away by LS3 Corvettes.

A little unrealistic. You can't just add hp numbers like that. I learned that a long time ago. There's no way a Camaro is going to be making 500hp with just headers, intake, and a tune.

Catbacks are usually only good for 5-10hp at the most.

It all depends on how restrictive the stock catback exhaust is (which we don't know at this point for the new Camaro SS). The catback on the GTO's is actually pretty good. Guys are only seeing 5-8 rwhp at the most by swapping out the stock catback. Most guys swap out the stock catback strickly for sound (not performance).
To be honest a catback exhaust is one of the worst power vs cost mods there is.

The best mods are long tube headers and a tune.

I just want it to roar when it goes down the street... not to worried about HP (has plenty lol) I was just wondering how much more it would get

OK, let's put a cam in it then. I just want to run even with LS3 Vettes. I'm not sure how much hp we need to counteract the weight difference.

The GM rep at Barrett Jackson said that the cai and cat back exhaust would being the HP up to 439.

That sounds reasonable to me, although it surprises me that GMPP would release official dyno numbers.

That's not a bad bump up in HP while still keeping your warranty and probably adding a nice note to the exhaust.

[radz28]

X3 It's not a whole lot, but we're pretty close to the 'Vette, power-wise, so it's not much of a suprise to see (possibly) that the gains won't likely be huge. I don't have a problem with this so far; it'd be nice to see a little more power, but hey, we're starting off with a pretty good amount as it is

[Edrock]

If CAI and catback boosts the output up to 439 HP, what would it be if you added the Shorty Headers into the configuration? Anybody have a reasonable guesstimate?
