Default Does Mopar/Catback Exhaust Increase HP?

I am looking at getting the Mopar exhaust for my SRT4, and am wondering if that will increase my horsepower or torque at all since I am running stock... Well I have a CAI and OCC...
Is the exhaust something that only helps once you mod your car with stage 1,2, or 3 or other turbo mods and such???

Thanks
Andrew

5 HP maybe?? even with Stages it's not leaps and bounds... and you won't feel 5HP... just a guess.... the Mopar exhaust is rumored to only be good up to 300(?) HP...

If you are going to stop at stage 2 it will be fine, and add a little power. It will help the car reach its potential with s1 or s2. If you think you'll end up going to s3, think about a 3" exhaust.

you get a lot more trq... and it helps with other mods a lot. i think its retarded to build up your engine and leave stock exhaust.

I've always heard the numbers thrown around on how much power the Mopar/Borla exhaust is good up to, but Mopar has the 355 horsepower rating on the Stage 3 with 100 octane and the Mopar/Borla exhaust. So it should be good up to 355 horsepower at least.

Here it is straight from Mopar: "The Stage 3 Kit with Turbo Toys in high-octane mode increases power to an amazing 355 hp at 5200 rpm and 365 ft.-lbs. of torque at 3200–4800 rpm! The Mopar Performance Cat-Back Exhaust System (P4510461) is required to obtain these power figures."

I don't know about the 3" o2 pipe, since I am going to get s3, eventually, I decided not to do it since it isn't compatible with the s3 manifold.

I can say that a 3" dp made a big difference. After that, adding a 60 mm tb finished off the airflow nicely.

You're the only one I know so far, black4. I may be there with you soon, though. Just trying to prioritize my mod schedule - It is in there, though.

you know how it felt when you went from stock to stg 2 the throttle response difference know imagine the same step up in throttle response again it eliminates a huge bottle neck much better power below boost,not to mention it spools so quick now its hard to stay out of boost. highway pulls in 5 gear lets just say even going through the moutains i dont have to dowshift out of 5th gear any more.

That is tempting. I found similar results with just the tb, I wonder how much the manifold does. 630$ is a chunk of change, though. Do you know of anyone who just did the manifold? I would love to hear about that experience.
