That sounds like a question that could only be answered by experiment. There are too many variables I think to make a prediction as to what would happen. I wonder why the high flow cat has no sensor socket?

I depends a lot on the car but probably no more than 8-12 HP.
 
There are tons of things you can do to that engine. Time for some homework to plan your project!

#53 of 78 replacement muffler and Exhaust by hockey3

I have to replace my stock 2001 MDX muffler & exhaust due to car accident. Is there a replacement aftermarket that will improve performance either HP or fuel economy.

I think only if you use a free flow catalytic. If you just attach pipes to your existing catalytic, I think you'll get more noise and very little HP.
 
Again, you have to think of your car's engine as part of a LONG pipe...starting from the air intake to the air filter and ending at the tailpipe. If you don't do stuff in the middle, doing things at either end really can't alter the situation a great deal....a little but not much if you look at it this way.

Hey guys,
 
As known with the 5.4s I have exhaust manifold problems/ w/studs. The passenger's side has a crack in it and the drivers side needs to be removed, magnafluxed/planed and put back on. Should I replace them with headers or replace/repair/ the stock ones. If headers are the trick, what about sensors and stuff- one hypo shop says they aren't an issue, but a Ford dealer says my engine light would be onall the time (Ford dealer I believe was assuming). One guy told me to keep stock remove the muffler and run straight back off the cat. (sounds gay)Should I take out the y-pipe and run duals to the back? What has someone tried and figured out before I spend time and money with this thing- I want to get more HP out of it if the price is all the same. Am swapping in a Airaid air intake system too.
