I have a 3 inch bell mouth. The bell mouth is open all the way around where it fits the turbo unlike the standard pipe which is just one hole. Bell mouth is better in my opinion.

2.5 or 3 - I think 3 is good for performance and a small increase in sound although someone who has more knowledge might say it upsets back pressure. so not 100% which is best.

You need a good clean bore pipe with a continous bore all the way though think mandrel bend technique is best for this.
