So far this combo sounds SICK!!! Can't wait to add on the FI catback this fall

 

Honestly, just get a Exhaust depot y-pipe and call it a day, spending $1000 for a cat-back is not gonna get you the gains HFCs do. If I could do it again I probably would've just done that.

 

That is not a bad idea..i just love the look of the cf or polished FI from the back

 

I've got a different opinion. You don't experience the real gains for the FI exhaust (or any mod) until you're tuned. Or atleast that's what I noticed. Plus y-pipes I feel really restrict exhaust flow. I say always get a fatback with a true dual exhaust w/ x-pipe.

 

More air in, high flow cats and the restrictive stock exhaust? Doesn't make much sense to me. You need to have an exhaust to get the most out of those mods!!
I've got a Magnaflow catback that I no longer need since I turned in my lease. I'll let it go cheap if your interested, PM me.

 

how much? i have a 2008 g37s. new on auto anything 550.00 today only through calling in.
