Which magnaflow stainless steel muffler is the correct size for the SC300 to retain the stock look? I've decided to use 3in diameter dual piping and offset muffler inlet/outlets seem appropriate. But, what physical size (length) muffler is appropriate for these cars?

Goals: maximize performance while trying to keep noise as low as possible and retain stock look as much as possible.

I was considering the 5'' x 8'' Oval (part # 14264). Is this the correct one?

 

Many people have gotten this one.

sounds awsome & not overly loud.
