Not too long ago I bought SLP LMs axel-back to add to my '08 gt. Since I live in VA the LMs are illegal and the shop had to install resonators on my mid-pipe. I am happy w/ the sound but not fully satisfied.

My question is: what is my next step to increase sound/flow without being illegal, or atleast if I can get away with it lol

I was thinking of swapping out the resonators that they installed w/ the SLP LM resonators. Would this make a difference? What are my options? Any help would be great.

 

Well seeing that you have Axle-Backs there are a number of other things you can do such as buying new headers or even changing your Mid-Pipe to new one but with the cats its gonna cost you extra
