I can't imagine picking up 50-60rwhp with an air intake, catback, and slight tune. I'm thinking more like 20 or so. The exhaust is going to be next to nothing in gains, only sound. Vararam is good for maybe 10 hp. I wouldn't get my hopes up for big numbers but good luck.

In my experience at Xtreme - stock C5's with an A4 usually are in the 280-290 range for horsepower to the wheels. As mentioned above a catback exhaust generally yields little or nothing in the way of added power. A simple intake may net about 10 horsepower rear wheel. Cars that have long tube headers, high flow cats, an exhaust and an intake generally will get about 35 maybe 40 horsepower. So realistically you might wind up in the 320 - 325 range. 40 RWHP is a healthy increase for bolt-on mods like you describe. That's about 12%....but without headers, you won't see as much - YRMV.

Get headers, CAI, LS6 intake, exhaust and then go get your dyno tune for more respectable numbers, or go the cheaper route and just put 4.10's in the rear. You can easily pick up a used unlocked predator like I did for 200 and play with it until your ready for a real tune and then sell it to the next guy for 200.

Your mods will not pick up much, but do not get fixated on dyno numbers as they will vary by dyno. Just mod your car as you feel comfortable. Mods are kind of guess work. I have 401 rwhp out of my car with bolt ons, so I know what works and will be duplicating the setup on my Convertible but with a few tweaks since I'm only looking for 425 rwhp. The only real mod you have made to your car is the Vararam, the catback is just for sound. 
You'll get 20 rwhp from just a tune but you won't be even close to 350 from those mods.

Just curious why does Vararam and Vortex both claim 40hp+ with their cai? I know it's bs but noone ever seems to call them out on it? Where do they get these numbers from 40hp is cam territory.Just curious btw I have a vortex and a vararam air bridge(was previously installed from owner) not bashing just curious.

Seriously doubt you will see 350 rwhp with just those mods. I would agree that you might see 20 rwhp gain, but that's about it.

Vortex says the same thing though? Also where do they show that they show it under power? How did they measure this? 40hp is a HUGE seat in the pants feel I just don't by into the hype. If that was teh case that means a c5 with just a vararam/vortex should pull hard on a stock c6. Just doesn't add up.

how much hp?
you wont see much. I have a 2000 a4 and I have done those mods and more after that but... you car should make 290 at the wheels stock..with a cat back..maybe 1-5 hp if that and the vararam intake duct... is that the whole vararam intake system.. if so only if you are moving will you see hp increase..not on a dyno..and a predator tune.. no hp increase but you will feel a seat of the pants difference with your transmission. biggest improvement predator does is with the a4 and shift firmness and points. I also bought a predator but later got a dyno tune. Your car is an 02 so you should see slightly better hp since you have the ls6 intake. you might dyno at 300-305 max.. at the wheels. I dont believe any other stories because i have done them all in this scenario.

Hi (2002 A4)
I put on a Blackwing 160 deg thermo and a street tune by ECS and l could care less about rwhp. When l hit the gas it feels like a different vette from before l had ECS give me their tune. The shift points also helped.
While l can't talk about other tuners but l can say is that ECS knows their business.
Good Luck
Alan

i've had two circle D stalls, a 3200 in an LS1 GTO and now a 2800 in an L76 G8 GT and it really is a wonderful mod for the cost.
i think the cost will run around $1400-1500 for parts and installation.
