Thanks for the advice RamTex, I've been kinda thinking maybe I should rethink the shortys. I guess I kinda like the idea of more lowend torque... Coming from Honda motors I'm used to nonexistent lowend lol.

Just thought of another question and this may be a matter of preference . What's the best way to run my exhaust setup?
1.) True duals with each side of the engine getting a header/cat and muffler
2.) Factory like , 2 cats y pipe one muffler
3.) headers, 2 cats ypipe 1muffler ypipe duals
4.) duals with 2 cats h-pipe or x-pipe with 2 mufflers
5.) something that I did not mention here

Recommendations on size 2.5" big enough or 3"

Having a lower tstat will rob your gas milage. It dumps more fuel in because its trying to heat up the cylinders. In some cases, it makes your AFR too rich which lowers your hp and fouls plugs.

I hope this helps a little

The only reason to go to180 therm stat is when using a programmer to change timing.
