    excellent !!!

    I just put these on my 09 GT, had bullitt axlebacks on which sound great under acceleration but I wanted more sound just cruising. I also tried the pype bombs which were just way too loud, way to much drone at highway speeds, and got followed for awhile by the Sherrif. The FR500S system is just right, I recommend it- and fit and finish are top notch-

    exhaust in Canada

    got these shipped and picked up at a UPS depot on the border. I got them installed at shop....good thing as there was some torch work to get the stock stuff off. They fit great, are of excellent construction and sound fantastic. Great throaty sound on acceleration, but about the same as stock inside the car at cruising speed on the highway...no drone or resonance

    FR500 exhaust

    Very awesome muffler system. Much louder than the sound sample online. Would definitely recommend these to anyone who is looking to get that raw muscle car sound.

    Great Rumble

    Got them installed on my '09 Bullitt. It has a very nice idle rumble and throttling roar. I don't know too much about other exhaust systems but I think this was well worth the money.

    Top notch, perfect tone

    the bad: look at the picture. your tips will not be shiny like that. was a little bummed about the tips. Don't get me wrong they look great but should shine. Now the good. Installed in about 45 minutes in my garage. perfect fit. They sound amazing. No drone...zero. Makes your pony sound like it should and not some ricer. I just wish my tips looked like what they picture. over all i'm happy, but for over 500 bucks come on!

    M 5230-S and PHRP KR H-Pipe

    2009 GT500. Installed KR H-Pipe from PHRP and M-5230-S mufflers from American Muscle. Shop install with no issues. Initial run way down on power. Driving for 1 full day and engine seems to be almost back to original power level. Prior research said to expect about a 5 hp loss. No drone inside car. Tame at warm idle. Snarls on take off and sounds like my straight pipe lake boat at WOT. Probably not for anyone wanting a stealth exhaust, but if you want reasonable idle tone, quiet cruising and LOUD on demand you will love this exhaust combo. Previous combos: quiet stock and droning Flowmasters.

    FR500S axle-back: Bullitts should have been given these in the first place!

    Although I like the sound of the '08 Bullitt exhaust, it simply wasn't loud enough, and I constantly found myself in a lower gear--or just driving faster--just to hear the engine at speed. sadly, all I heard when driving on a highway in fifth gear was tire noise! The FR500S axle-back exhaust is an excellent alternative for '08/'09 Bullitt owners who want to keep the stereo off and enjoy some pony car music. The FR500S tips are identical to the Bullitt exhaust, and the cylindrical shape of the resonators fit the underside of the rear bumper perfectly. You can see the underside of the FR500S mufflers from the side of the car, but it is not unattractive IMO. If this is a dealbreaker for you, then consider Borla ATAKs. Furthermore, FR500S axle-backs make sense for S197 Bullitt owners, as these were installed on the GT500KR; adding FR500S mufflers to a Bullitt will complement the list of other GT500 items Ford put on the car (e.g., GT500KR rear axle, GT500 seats & steering wheel, etc.).
