I have a '99 Grand Cherokee Limited 4.7L v8 4WD. I was wondering which flowmaster would be the best choice all around for a single cat exhaust.
I am looking for best gas mileage, power, and aggressive tone.
I have come down to the Super 44 or the Super 10, I don't know exactly which would be better. Also, if I was to want to upgrade to dual cat.. Around how much would it cost for a stock or upgrade dual cat? And is a header upgrade necessary for the factors I am looking for?

 

i have the super 44, definatly a good choice for only about 80 bucks

 

I didn't like either, went with a standard thrush classic. Love it

 

did you have it on a V8?

 

Yep. Sadly, she is no more

Though i did go with another Thrush classic on the straight six too

 

sorry to hear that

 

Right but I called an auto center and they're charging 230$ for product and installation.. And I read it's recommended that the muffler be welded or spot welded with clamp. Is it inconvenient for self installation?

 

just bought mine for the 80 bucks then installed it myself using clamps and some tube laying around, then about a year and a half later i got it welded using my buddies welder
230$ is a rip off

 

Quoted for truth. I never got around to welding mine and believe me i made an honest effort at ripping it off in the woods.

 

Hahaha, awesome. Very much appreciated guys.

 

Hey boss ,,I ran the 44 than switched over to the series 10..i think the 44 should be fine ,,the 10 is twice as loud ,,good if you keep it offroad

 

The 10 series is way to loud for a daily driver, the 44 will be pretty loud as well.

 

i have the 40 series on my 4.0 and it sounds really tuff
