can anyone suggest a muffler (cat back I guess) that will replace the RFL i have on my sti. I have the whole RFL package, Turbo back and I need 3 inch and quieter. My wife is ready to kill me because every time I come home, there is a good chance I'll wake my 6 week old. Also the drone on my 45 minute highway commute is making my ears ring. thanks in advance... sleep deprived dave. And, yes, I knew what RFL stood for.
