This isn't me trying to be mean or anything. Just thinking out loud to the community that does stuff to make their exhaust crazy loud and raspy then asks others why is it like this.
I don't understand why people buy Roush or Pypes. By the time they figure out that it is too loud, then the effort and research they put in to tame the sound + As well as shop labor and additional exhaust components if purchased (resonaters, glass packs, shorty headers, etc) - They could have just spent a little more initially and got quality mufflers that didn't sound like s***.
I know this probably isn't helpful but it is something that has always bugged me. There are about a million threads, youtube videos, and reviews that say things like Roush mufflers being too loud, Too much drone, Too much Rasp, etc. Then later down the road the people add Longtubes or an X pipe then just seem baffled by the outcome of the car sounding like a ricer.
But to answer your question, getting resonators added or getting shorty headers will help tame the sound some. More time and $$$ though!
