I have installed a nice looking invidia exhaust and think that it sounds great, esp. w/ the top down - but on a daily basis, I need it a little more quiet. I have searched everywhere and the smallest silencer I have yet to find is 3.5". The twin tips are both 3" and I was going to drill a small hole in the bottom of each to allow a silencer to be installed from any other system out there - I just can't find the size I need. Any ideas? How hard to make my own? I really want to buy two (one for each tip) so to avoid any rattling in the exhaust from making my own. Thanks for your ideas!

 

Any ideas? I do love the growl, but there are times when I would like to have the option at least.
