Just ran cat back tubing...2.5" manderil bent, with no resonator. For now I left the racing beat muffler on which is suprisingly quiet....almost too quiet! Anyone have advice on which muffler to got with? (boom01) I'd prefer a chambered exhaust for a softer deeper exhaust note. (chair) Has anyone tried running a Borla, Magnaflow,Dynamax, or Flowmaster? If not...is anyone running a straight through exhaust with the tone I'm looking for? (confused) Any advice would be appreciated. (attn)
