Stock or not stock exhaust?
#11
There are GT500 FRPP mufflers, too, which are similar to Borla Touring. If you're have 4" slash cut single wall tips they are likely the stock GT500 muffler, which is a sweet piece as it is quieter than others and has a mellow tone. When you're better, have a look under the car and see if someone changed out the H for an off-road, as that'll dramatically increase volume, no matter what's out back.

talking about gt500 mufflers, are those technically legal in the 5.0 Mustang? I am not saying emissions but noise levels. I wonder what the Decibel difference is. I have Roush Axle backs and those things are loud when the engine is cold.
