Ok let me start off by saying i have a 08 g35x sedan. I already have r2c intakes. Still not enough sound. I am 36 with 3 kids but get an occasional heavy foot when i am alone or with the wife. I have narrowed down my 3 choices
1. Fi Cbe with 18" resonators and fi rhfc
2. Tanabe axleback with fi rhfc
3. Invidia CBE with fi rhfc I know i have to modify the y pipe.
To me the tanabe sounds the best especially on coupes. But the FI is in a close second followed by invidia. I am looking for that exotic sound. Something like a s5. the s5 is quiet when cruising but punch it and it sounds really good. If this is even possible, especially since i have a 5at. I have literally read thru all of the exhaust posts, and that is why i chose those 3. For those that have had these combos can you advise me on the correct way to go. Sound, looks then power in that order. Which will be the most conservative?

 

look in to Exoticspeed, I have had mine for over two years and I think they now have a sedan version. Very different. Everywhere I got I get compliments and asked "whos" system is it? Very different an not many of us out there.

 

I have your choice #1 on my 08 coupe. At cruise, it has a little rumble but when my heavy foot has at it, the exhaust really comes alive.
