Product Information

MSRP: $360.00
Average Price: $162.32
Manufacturer: Flowmaster
Yes: 31 / No: 1

sounds great when taking off, dosen't drone in the cab, and the sound volume goes down when at higher RPMs. Got better throttle response after I added this too.....People definitely know my exhaust is not stock with this.

BTW...I just welded it in with a factory tail pipe..and on my LJ, I had to put in a extra piece of pipe due to the length difference from the stock....about a 10" piece.

Pros: Low interior noise but can still hear a nice rumble
Cons: None really, maybe wish it was louder sometimes but I'm happy with it
Recommended? Yes

Comments: Bought the flowmaster delta 50 series after my cat fell apart and clogged up my stock muffler, had it welded in at a local shop. Has a nice low rumble at idle and makes the nice gurgle noise when engine braking.
It's taken a beating and hasn't failed me yet!

Pros: Good sound
Cons: Slightly too large
Recommended? Yes

Comments: Installed the Flowmaster 50 Series Delta Flow muffler on my KK. I also removed the resonator and replaced all the pipe from the muffler back with 3" pipe. I've seen decent gains in horsepower and a slight gain in mileage. The sound is very good. More mellow than the Super 44 or 40 series but still noticeably more aggressive than the stock sound. The only issue is that the muffler is slightly too large for the KK and hand to be mounted at a slight angle in order for it to clear the frame.

Pros: Better low end grunt. Nice deep tone at idle and quite at cruising speeds.
Cons: None really
Recommended? Yes

Comments: Sounds much better to me than a 40 series. Does not have the hollow style sound of the 40 series. Has a nice deep idle sound like a small block v8. Very low interior noise with windows up. Can barely hear exhaust sound at highway speeds.

Flowmaster Delta 50
Pros: great sound, very little drone, not loud
Cons: not loud, little if any preformace gain with stock pipes
Recommended? Yes

Comments: bought it at a pick and pull for just over 20 bucks, and 50 to have a local shop weld it on my 4.0L XJ. it's got a very mellow throaty sound that's not too loud. didn't notice any preformance gains at all, but all i did was change the muffler and keep the stock pipe. best yard find so far. love the sound. it's just loud enough, for me at least. others may want something louder like a 40 series.

Comments: I installed a 2.5" muffler along with a custom 2.5" (ID) tail pipe. It opened the engine a bit in the higher rpms and it sounds great.

Comments: Installed flowmaster 50 SUV in place of stock coffin muffler, leaving stock resonator. Sounds nice at idle and under load, but drones terribly at light throttle, when MDS is activated, and at steady throttle 1800-2100 rpm. Am replacing with magnaflow 3in universal ASAP
