I wasn't really expecting much improvement but I was suprised, there's a nice difference in sound and power. A nice deep low tone and a definite power gain. I painted it with black high temp paint. It looks sweet. I have the second one too for going duals in the future. Got them from V6Mustangstuff and it was the right part number from a M/T stang (FI-7849). This mod rocks!

 

I just ordered mines from Ninosport and cant wait to replace my stock muffler.

 

cool that you painted them. now you got a high quality muff that not only performs well, but looks good also. nice job.

 

They sound so much better too and really lighten it up too.
