For those kind enough to post reasonable guesses, the person closest to the actual, I'll send you a $20 gift card from Autozone. I plan on dynoing the car inside the next 5-6 weeks. To sum it up for mods just in case:

SLP CAI & Lid.
Hooker LT 1 3/4" headers.
True-dual 3" exhaust w/x-pipe and 18" bullet mufflers.
HP Tune (LTFT & STFT, knock & advance adjustments)
160* thermostat.

My last dyno through gutted cats w/same induction, stock Ypipe with lowmaster 80 with 3" cutout and stock thermostat. This was the same setup I used for my 12.71 run at the track.

Car has 112K miles on it as of yesterday and currently knocks down 16mpg around town and 28 on the highway. No smoking and it's an M6.

Thanks!

Duff
I say 352.84 RWHP

I think you should dyno the car without 160 thermostat and with it, my engine performance teacher insinuated a lower thermostat decreases hp because of a slightly reduced internal combustion temp and pressure and increased quench zoning, but they seem popular on the street, itd be nice to see some solid evidence so you know you rshit when other ppl dont

I'd say 330-340rwhp.
I like to guess low so when it comes to finding out i like to be surprised!

I am guessing 310rwhp for my cars' set up and i have an A4. I will be finding out what it really is in a few weeks. (Mods in the sig.)

345 Hp and 364 Tq is what I'm going with... So basically your old numbers are factory headers and y? Other than that no real difference besides a little more free flowin exhaust?

Just making sure... I've actually seen a couple cases where guys lose HP when going to Td's from a y pipe/cutout setup.. Guess we'll see.. Good luck on the numbers..

What gear ratio are you running? If it is stock 3.42 I will guess 340.77 rwhp and around 351 rwtq.
