Just wanted to say hey to everybody, i'm new to the site. Couple a questions for you guys. Got a 06 scab fx4 and want to put both intake and exhaust on it. Heard great things about the af1 but i hear I'll have to use the 3'' instead of 3.5'' so i don't get a lean. Is that what everyone would recommend over say a volant. I was thinking about running a siso magnaflow system with an 18'' because i don't want something obnoxious like on the highway but still have a nice rumble on startup and idle. would the sido give me more sound. I heard the siso on the magnaflow and it doesn't sound all the loud. Trying to order stuff now so i can install when i get home from iraq.
Thanks

 

Hey jc, I think you'll be very happy with the 3" AF1 and 18" Maggie..

Gonna be great sounds, some extra HP and torque and some better mpg too.

I gained 1.8 mpg highway just with a Borla cat-back, I'm sure the Magnaflow will be about the same.

I also have the 3" AF1 intake, and that's where you'll notice a difference in the throttle response. Other than tunes or gears it's a very good bang for the buck!
