I am always in for something else, because i want the best.
Not that this mod is the best but it is different.
I took a cart of a M401 and cut off about 8mm and insert it in my 510.
I is a whole new demension of the 510.
I cannot say more or less vapor or smoke but i like it too.
Maybe the air intake is better.
i say try it and find out. maybe you like it because everyone has a different taste.
