[QUOTE="nikhsub1, post: 1290839, member: 22952"] Back to reality... The OEM cats are not high flow cats. I've seen 1500 cel thrown around, like I said before they are dense and do not flow well, no matter what kind of temper tantrum forzda1 wants to throw. Most of the after market cats are 200cell, or over 7X less dense than OEM. I have a race cat sitting on my desk, it is 200 cel and I can see through it. Now, I have no OEM cat from the Raptor here on my desk but I would venture to say, you could not see through it at 1500cel count. Anyway, there may not be tons of gains from a high flow cat on this application, I don't think that is the case but it's possible. For anyone to say that the cats are fine and don't cause any restriction without testing is just asinine. I'm not trying to beat a dead horse or be difficult, but no facts have been presented one way or the other even though forzda1 keeps saying he has presented facts. If I've missed them somewhere, please point me to them. [/QUOTE]
