Does anyone have dyno sheets compairing different size exhaust tubing? say 2.5" vs 2.75" vs 3" I know that each brand and the muffler will make a difference as well, but i am trying to decide on the tubing size at the moment.

I am looking for the most "area under the curve", not just peak number.

thanks!

2.5 7-11hp catback exhaust

2.75 header back exhaust if you can deal with the noise is probably going to get you the most power

3"no need for it unless your FI its too big fo N/A

single exhaust-your going to get the most horse power
