Thanks and good luck.
Not trying to sell you on the FX300 but IMO, it is much smoother than stock, easier to modulate and drive smoothly than stock and there was no noise increase that I noticed.
I have only had it for 700 miles so I am still in the honeymoon period..so I can't comment on longevety and/or glazing issues. I also never launch it or beat on it..i just thought the extra holding power (along with zero drivability issues) made the 300 a better choice for me.
As you probably already know, the ACT are known to be noisy (that's what scared me away from it) but they do have a proven track record.
