from what i have seen being posted on the boards, i would get a fm 70 or another brand of chambered muffler. i have a straight thru muffler on my '99 2valver and it sounds great but when you put the same system on a 3 valver, you get horrible droan and its usually to loud. you probably wont notice any power increases or mileage differences (well until you get it out of your system, you probably will have a VERY heavy foot, which will decrease your mpg) changing the exhuast seems to be more for just the sound your looking for your v10 to make.....
