I don't like to guess HP gains, but it should sound mean as f#*k with the supermaxx and loudmouths! Your going t need a tune once you have that stuff installed to see the full potential of those mods, the headers and intake can really screw with your air fuel, keep us posted with the outcome

I installed an exhaust similar to yours, but used the Magnaflow. After a tune with the handheld, car posted 351/360. The only other mods at the time were free TB bypass, crane 1.8 rockers, donaldson and VHP thermostat. Healthy A4 baseline is about 290 rwhp.

Just find a good tuner who can tune it on the dyno... it's the only way to go. Check the sponsers, I'm sure you can find someone close to you. It will be money well spent!

i dont know about hp, but i have almost the same mods in an a4 vert and ran 11.9's at 114. it may only dyno 320 at the wheels, but at the track and on the street is what matters to me.
