I have a 2010 mustang gt. I already have a few mods. Intake, bigger throttle body, and a Bama tune. I was think if I should get me FlowMaster Outlaw exhaust because I'll know it'll make it sound even better with the mods and getting rid of my old exhaust. Or should I go with 3.73 gears? Need help deciding. Thank you

 

Duh...both!!!

 

I wish. But right now I'm still in high school and need the extra money since I work weekends only.

 

do the exhaust you will turn heads all day long
I got roush axle backs, sounds like a 70s muscle car love it
lots of compliments

luke from the north ehhhh

 

Get 4.10's....

 

Hmmm, sound fast or go fast? What gears do you currently have? If you have 3.55 then the move to 3.73 ism't going to be very noticeable.
The other thing is you're still in high school, the local law enforcement love harassing young people, a loud exhaust gives them a reason to pull you over, just saying.

 

If you're going to do gear go 4.10's if you have manual trans, I did 3.73's and switched to 4.10 less then a week later

 

u cant go wrong with outlaws or some gears. Get yourself an offroad h pipe and you will be blown away. Exhaust or gears? that kinda tough. Both bring a lot of joy. Probably exhaust.

 

If you want the car to sound faster, get the exhaust.
If you want the car to go faster, get a set of Steeda underdrive pulleys and Steeda charge motion delete plugs.
If you already have 3.55 axle gears, keep them. If they're 3.31, change to 3.73. I know some guys say go for 4.10 but what they don't tell you is that they render 1st gear almost useless.

 

I use 1st gear all the time (except when wet or cold). You just have to learn how to drive it.

OP, you can see my mods for power in my signature with dyno numbers. Exhaust was Mac Long tubes, Mac off road ProChamber, and Mac and Bassani mufflers (which do almost nothing for power).
