So my question is if I cut out my stock muffler on my 08 2 dr JK would it effect my jeeps performance or gas mileage would there be any negative effects?

The sound gets annoying and depending on where you live, it may be illegal. I don't think you would see any performance increase. Maybe the opposite with the lack of back pressure.

I took mine off just to see what it sounds like. Its sounds like crap when you get into high Rpms.But I also have a 2013 so I don't know if it be the same sound for a fact.

Never go full retard. The 3.8L running straight pipes sounds pretty bad and there is zero performance gains.

You'll lose low end torque.....and it'll sound like crap. Wouldn't recommend it.

X2 on the loss of low end torque which is crucial to off road performance. Properly tuned straight pipes will increase HP a little on the very top end, but that's it. I'd replace the stock muffler with a good one from Dynomax, Flowmaster or any reputable manufacturer. You'll get good sounds and small improvements in power. That's about the best you can hope for these days.:twocents:
