Here are videos comparing before resonators and after resonators.

Before.
YouTube - Mustang SLP LM with prochamber and hi-flows

After.
YouTube - 06 Mustang GT, Prochamber w/hi-flow cats, 12" resonators/glasspacks, SLP LM

 

Sounds awesome and mean in the after video

 

sounds really good!!

 

Got rid of quite a bit of that crackly crap sound.

 

That it did, but I wonder if that sound will come back once the resonators are broken in.

 

You are correct, they will. The rasp was almost gone when I first had mine installed, now its almost like they arent on. I mean its not quite that bad but not near the same.

I think, as others have found is that were not going to get a loud sounding car w/o having the rasp. Im pulling mine this weekend and switching to magnaflow axle backs. It will be louder than what i currently have since most of the loudness was gone after the resonators were put in.

 

Sounds awesome but the pypes mid muffler would have sounded better!!

 

It was kind of a toss-up. These may be a little louder than the pypes, but the pypes may produce a little deeper tone. In person it sounds a lot better than it does in vids.

 

It sounds really good in the vids.

 

Thanks. Are you going to get off work to go to Fabulous Fords Forever?

 

Any chance its on a Thursday or Friday?

 

Nope, Sunday. Take a sick day of leave.

Much more mellower on the inside. Drone is still there, but you no longer have to try and talk over it
