I use REAL turbo mufflers whenever there is room. The "turbo" name came from the muffler on the turbocharged Corvair Spyder from the early 60's. GM knew a lot of people felt like Jerry about noise but that a turbo charger must have unrestricted flow or the performance tanks so they designed a muffler that under normal driving routes the flow through all the baffling and is quiet. With the turbo on high boost the increased exhaust flow by-passes the baffling and sounds quite throaty. Now 90% of the so called turbo mufflers are just a name printed on the box to appeal to the same ones that love to say " 4 bolt main" or "double pumper" to impress their buddies.
