Replacing the w brace with sway bars

[M_1313]

Hi guys,

I am currently shopping for an exhaust and I am quite in love with the motordyne e370. However, after researching, I am scared that the sound level might be too high. I have contacted Tony to discuss any other options and he told me that I could use a slightly longer muffler (the one used for the q50) in order to reduce the sound level. However, this exhaust requires the removal of the w brace. From what I've read online, the w brace helps to stiffen the chassis. My question is, do you think that removing the w brace and adding adjustable sway bars is a good idea. If yes, do you think I'll have a car with better/worst/same stiffness/handling capabilities?
Thanks
