Default Looking for options to make 400-450 rwhp

I have a stock 1999 SS A4 with 3.23 gears would like to make 400 to 450 rwhp. What are my options to accomplish this ? Would be a weekend driver and not track, but plenty of street muscle with a back off sound.
Thanks

You have a budget?
E.t / trap goals ?

Full exhaust, Ls6 intake, cam = 400 whp
Fill exhaust, intake, cam, heads = 450 whp

More to it but that's the jist of it.
You will also need a nice converter.

Here is my back off sound with the setup in my sig.

I would like to do heads, cam and converter. Budget is only reliable parts not just name brand.

Like listed above 400 hp with bolt ons and cam and 450 with heads on top of that. You could also just do a few basic bolt on mods with some nitrous or skip all of this and just do a blower

You'll gain more power with just the cam on stock heads

Yeah, you can hit your goal with bolt ons and a decent mid range cam. Like the street sweeper HT or the titan4. Fast intake, long tubes, should get you near 425 right there.

Looks like a nice case of just enough cam to let the heads do their stuff!
