For a couple of years until it rots away.

 

Just Did a Cherry Bomb Extreme on mine and couldnt be happier. Very timid at Idle...then really wakes up with a little bit of throttle.

 

I tried several different variations in mufflers. I think I finally got it right. Lose the front resonator, flowmaster 40 series muffler, keep the stock tailpipe with resonator. It is enough sound without cabin noise or low rpm drone. Hope this helps.

 

Mde too!

 

* Me too!

 

What magnaflow do you guys have that doesn't have the noise? I've got a magnaflow and am going to replace it as soon as I've got the time. Its REAL noisy in the cab, when I've got my trailer hooked up, the drone is earnumbing. Within an hour my ears are literally ringing.

 

I run electric cut out 99% of the time. who wants to have a convo? lol but seriously I talk on my phone with it open and it ain't bad. closing it and I barely hear my super 40 flowmaster. no joke it sounds like stock when I close it. guess im used to it?

 

I just got a 50 series flowmaster (just the muffler) on my 04 hemi sport and was wondering how long does it usually take for it break in and stuff

 

bout the time the rust takes over lol
