I did get the Dynomax 3" ID/OD Race Bullet mufflers Part #24219.
The mufflers are perforated 3"in/out, 23.5" long,18"L/ 4"W casing.
Mods in process now at the welder's also included new merge collectors which I was conivinced would provide 15HP gain due to the smooth shaping of the air induction from 4 pipes to the straight 3" pipe. There is also a spike inside the merge collector to smoothen out the transition and put a slight spin on the exhaust. Similar merge collectors can also be purchased by Hooker or Dynotech in JEGS. I went for the MC's because of the 15HP brag but also for uniformity. They are installed by cutting the four pipes after they turn down the side. The MC will lead to butt welded 8-9" tube staying at 3" ID, flowing directly thru the 3"ID Dynomax and out at 3". On the exit we will slip the 3.5" exhaust cut out over the outlet and weld that to the muffler casing. The Dynomax mufflers are very well constructed using a fiberglass mat, wrapped in SS wire , gauranteed not to blow out.
Hmmm...we'll see ! I do think Red's SSS mufflers are better quality however. I'll send you photos as I'm not too good at posting them.
