[QUOTE="stangin, post: 634984, member: 7899"] Ok, here is an interesting note: I made 444/469 with the exact same mods with my Eaton, but here is the kicker.. I had and still have the stock cat back which everyone says is restrictive.. vs the magnaflow cat back so the numbers should be higher than mine, I produce slightly more torque.. granted dyno's vary and conditions etc.. I just find this interesting and I really feel that there should be some back pressure. Headers with a free flowing cat back system.. maybe loose some torque, hmmmm. I wonder if headers would benifit me more than most with no loss of torque with my o/r x and stock cat back giving some back pressure, I never thought of this, it scavenges the air out of the engine via header and o/r x.. has lots o room for the expanding exhaust gasses coming out, before the mufflers and as the exhaust gas cools a little (it cools by the time it gets to the stock mufflers somewhat) and being cooler needs less room to expand so would actually draw the exhaust gasses out through the mufflers and cat back. An interesting thought.. [/QUOTE]
