Looking for a muffler for my DD Spirit, planning on at least 2.5 or 3in, no cat, currently running a mitsu turbo but I'm not worried about boost creep. Mainly just want it to be fairly quiet, I have a bullet on my 87 Z and that's to loud for a DD. How does the super turbo muffler do quieting down the exhaust? Anyone run one of these? How about placement. I'd prefer putting the muffler where the cat was and just having a straight pipe out the back for easier clearances.
