    5 Top Rated Questions

    My piping on my 04 GT are 2.5 inches, will this muffler still fit ? Because these flowmasters have an inlet/outlet of 3 inches. Will the Flowmaster Venturi reducer cone help out? And be a perfect fit

    • Running the 3" Flowmaster Outlaw Shorty Race Bullet Style Muffler on a 2.5" exhaust will require adapters to connect this from 2.5" to 3" and then back to 2.5" on the outlet. Keep in mind most chambered mufflers and turbo style mufflers for the 2004 GT will use an offset/offset inlet and outlet that will require additional modifications to the exhaust piping to fit this center/center inlet and outlet muffler.

    I have the super 44s on right now but if I installed these outlaws in place of the super 44s would I be losing any performance benefits because these are more straight through ?

    • Depending on your specific setup, the Flowmaster Outlaw Race Muffler may cause a slight loss in low end power production and throttle response. This will be based on the exhaust flow and backpressure on your current setup.

    Does any one know or have any information on how this sounds/compares to the slp loudmouth 2? I cant seem to find any sound clips of this particular outlaw muffler.

    • The Flowmaster Outlaw Shorty Race Bullet Style Muffler will be significantly more aggressive than the Loud Mouth 2, with the Flowmaster being more Akin to the original Loudmouth mufflers.

    What exhust pipes is best for this Item?? I plan to renew all my exhausts under my 1995 mustang v6... Maybe will add long headers.

    • if you are placing the entire system we sell exhaust combos or the exhaust systems in 3 major parts. Buying them in sets or whole will save you in the long run. Or you would have to modify the exhaust system with straight pipes. Here are a few options. Or combo units minus headers

    Can this product replace my 40 series mufflers on my dual exhaust?

    • This muffler can replace your 40 Series muffler. You will however need to make some adaptations to mount it to the exhaust system you have on your vehicle.

      Awesome; Bad to the bone! Just the sound I wanted!

      Fantastic sound for my Supercharged, Dual Stage NOS 03 Mach 1. It has the specs but needed "That Sound"! Well, I got it with these gems. I love them and it turns heads.

      Can't truly review this product.,as I lowered my mustang before the mufflers came in ,now there is no room underneath to keep them from dragging . But I'm sure that they would of sounded badass. So I rate them a 5.

      The Best Choice!

      I have these outlaw mufflers on my 01 mustang gt and it was best choice I ever made for my mustang. I've tried other muffler that were good but these are the best. Very aggressive and respectful without a drone. Heads will turn and look at you and say, "she sounds beast bro." "What you got under there?" I would say, "It's Outlaws Mufflers, all day baby!"
