Does this seem right for an all stock 2011 wrx with straight pipe

238 hp 266 TQ to the wheel's.
Different dynos will read different numbers. A straight pipe by its self isn't going to yield much of a gain.

If you go to the Cobb website (CobbTuning.com - COBB Tuning Home Page) you can dig through their database, but honestly you can't compare unless it's all done on the same dyno.

Here are some numbers from other stock 2011 wrxs from the Cobb site (all on different Cobb dynos):

223 hp 255 ft/lb Stock Baseline

251 hp 255 ft/lb Stock

217 hp 252 ft/lb Stock Baseline 2

You might have freed up like 5 hp/tq with a catback... Stage 1 tune would get some some better gains.

This.

The catback will yield next to nothing on a stock car; you basically got a baseline reading of your car done. Use that to compare to your future dyno graphs from when you get tuned.

I feel like the straight pipe game me a few horses along with better throttle response.
Probably more in your head than anything. The converters are more of a restriction than the exhaust behind it. Without reducing that restriction, you're just making more noise.
