Default 2.5 RS factory exhaust question??

I am about to replace a really loud and bothersome muffler I had put on my '05 RS. I was just wondering if anyone knew or had any wild guess about how many decibles the stock muffler puts out on an stock 2.5 SOHC with the subaru sport tail pipe? thxs-- andy

Hmm... My guess is "not much." The Hayward & Scott puts out a bit more than the Prodrive, which itself I think is like 89 or 90db.

All things being exponential, I'd say stock is, what, like.... 86db?

i would say ~87 somewhere around there. but its not the actual DB of the exhaust that matters, its the tone.

that is very helpful.... thanks for the reply's.. and that is a really good point about the tone.. did'nt think about that! the stock one doesnt have much of a pleasing tone.. where really quiet aftermarket ones like SPT or Apex'i WS2 prob sound better than stock but are around like 89 DB's only
