    best sounding muffler

    looking for a bit more power out of the jeep to tow our new boat.

    planning to get the mandrel bent pipe from Rusty's and i need some ideas on mufflers.

    i'm partial to the magnaflow straight through design (have it on my 450hp camaro) and it sound nice and mellow but flows GREAT.

    i'm also considering a flowmaster 40series.

    even thought of doing a dynomax bullet (cheap).

    any input? never really heard any exhaust setups on a jeep.

    Re: best sounding muffler

    I've heard good things about the Flowmaster 40 series. We're hoping to do a review of different Jeep muffler/exhaust setups at some point in the future so I'll keep you posted.

    Re: best sounding muffler

    I put a set of the standard Dynomax mufflers on the CJ. I want to say it was with 2.5" tubing. Ran them with the Jeep 360 and now with the Chevy 5.3. They are quiet inside the Jeep, but have some good sound if you are standing behind. I prefer the quieter exhaust on my Jeep, but I guess that is personal preference. They definitely have good flow and available at Advance Auto for $35.

    i feel the need......to say....

    my camaro will SMOKE all your jeeps....on a paved road


    oh....
    "Jes curious........how have you confirmed the 450 hp ?On a dyno,uncorked headers?pump gasoline with out funny gas?Odd it zackly 450,but,not trying to start any wars........jes curious."

    dyno tuned 382hp at the wheels on a slipping clutch

    since then i've gone from single 3" exhaust to dual 3" pipes, race clutch with light flywheel, harland sharp full roller rockers, and found out the throttle body was only opening 85%...fixed that!!!

    so i should easily have picked up the last 18hp to make it about 400hp to the wheels. then a conservative drivetrain loss of 12% (very conservative...probably more like 15%) yields a 448hp at the crank. so i think 450hp estimation is accurate

    Re: best sounding muffler

    My little modifications will not be a world beater,jes a bit better than stock so far....I am more interested in reliability right now.If i get serious about power....I will start with one of my 440's and a 6 speed 727 etc.......workin on a 55 Plymouth wagon with an 6 speed 727 and an 578" Hemi right now and its gonna be a super street sleeper...no wheel tubs,jes moved the frame rails inboard to accomodate an 9" tire and with about 4:30 gears.....even at 9.2 ratio....make about 500-550 easy to use HP.As I have proved a lot thru the years,ya dont gotta get crazy.....jes make sure things work well together!Have fun y'all

    Re: best sounding muffler

    Just my opinion.....but, I love the Borla header and the Flowmaster muffler setup. I have had that in place for the past 5 years and it has served me very well. It has a great sound....kind of "throaty", but not too loud. I have some other power upgrades in place also....
