flows give off a nice , decent loud, rumble at lower rpms, i haven't heard a mac setup yet but the flow 40 is the way to go

 

ive heard both, macs sound like pissed off bumble bees flying behind your car

 

hey so your trunk blackout is like a sticker? how much was it?

 

is a vinyl but yea w/e
30 some odd dollars, its a pain in the *** to install, hope u have a lil experience with vinyls before u install it
u will need a water bottle, squeege, and a hair dryer to heat the vinyl
great product tho
i have the gloss black, matte lookes good also tho
make sure u get it from krowbe!

 

well what is your oppinion on the non vinal ones... like the kits... i guess its plastic.

 

ive got mac, and i think it sounds great, its really low at idle, and however when its gets up to the higher RPM's it does tend to buzz a little bit, ive heard a guys car around town with flow 40's and i like the sound of mine all around better.

 

ive got true dual 40 series flows and it sounds mean

 

From what i have heard, MAC's sound better with a catted setup. Flow 40's sound way better with a O/R setup.
