I'd like to put a flowmaster 40 on my 2000 xj. Does anyone have this muffler and are you happy with the sound and performance?

Thanks

 

sounds the best and preforms the best on a I-6

 

i like the one on mine but it gets on my nerves at highway speeds bc i put a turn down right off the muffler. when the engine boggs down it will just rattle your brain. but other than that it sounds awsome at idle.

 

i have one on my 2000....sounds great!

 

Thanks fellas I appreciate it.

 

Anyone running catless? Would that make any diff?

 

It will not pass inspection where I live. And probably a bit louder

 

as long as you dont tell... lol im running catless. it makes it sound much deeper. i also have a cute (i hate chrome) "boom tube" on the end that makes it sound deeper.

 

I gutted mine out. Deffinetly sounds better! Is there anything i have to do with the O2 sensor?

 

your boned on the O2 (if your ride has the OBD2. 1998 and newer.)
