Wow, thats a big pain. Before I read this post, I thought I am the one who is paying the most expensive insurance for a G35. My insurance is $247/month. Sorry for you but it makes me feel happy now. LOL

 

 

there is your video

 

Man, you will scare people on the street and some elders may get stroke by that noise.

 

i take that as a complement..thanks

 

sounds good but the echo off the concrete makes it kinda hard to differentiate from the sound and the echo..... oh, and turn your lights off....

 

yea... but it sounds different for sure. exhaust itself sounds hard but dang... that sounds really bad *** bro

 

nice vid, but by taking in a parking gargage just makes it sound loud and echo. We can't realy hear the real sound...

 

i gotcha...lol freakin hilarious about turning the lights off..haha..but yeah...
