Fellas before I departed for my overseas tour I had a few mods done to my 08, a6 coupe. LG Super Pro headers, Catless x pipe and halltech killer bee w/hive in addition to a tune. At the time I still had the crappy non npp mufflers in line with the headers. I still had stock plugs, wires and roughly 45k on the odometer. I managed a solid 401.4 hp and 405.6 tq.

Since then I have added borla stingers, new plugs, wires and in the process of adding cats. How much more should I gain with these additions? How much sound will the cats cut down and hopefully no more than 3 hp/tq. By the time I hit the states again I hope to have a ported ls3 manifold as well. Do you all think 420 to the wheels is possible with those additions?

Here's a thought; put it on a load Dyno for a few pulls and see.

Hell all I will say is throw a cam in that car all I will say is 440 whp to 470 with a nice cam and good torque to boot.
