I didnt mean that it actually helped mileage, I meant that whatever minimal gains it gets from that (if there are any?) it is not much better to use a $250 aftermarket over just the ford cone.

I agree, anyone who thinks that this will actually do anything to help gas mileage or performance is HIGHLY mistaken haha. It just sounds cool

For the exhaust. If you take the last muffler off you car its a subtle noise. The intake with no cover is louder then the exhaust with no back muffler.

I only deleted the bottom muffler under the filter. There is a hole. Just seal a cut peice of plastic over it. Don't remove something if u don't have to. Not sure on an exhaust yet????

I think that best bang for your buck mods would be CAI, race header, 2.5" exhaust, with a tune. Unfortunately, I haven't found anything except the ford racing exhaust. It would be nice to see the ~200whp NA that I've found with 2zz-ge.

Tom, since you worked with these engines before what are we to expect with simple bolt ons and a tune, ie: CAI, header, exhaust and a solid tune?

The engine responds well to mods , I 100% cannot stress enough that no mods need to be done till tuning comes out

This is a Diff ECU and a lot of new things on this engine that no one on this site has messed with I would be very carefull

Fuel pump driven off the cam , makes SERIOUS PSI change the fuel pump gears to make even more volume and psi , direction injection into the Cyl where the Inj wont have to be changed till about 450-500HP to the wheels and it goes on

Wait for tuning


Tom

Any development of the tuning part has anyone been able to get into the ECU and tweak with it yet?

There has to be more companies than SCT working on this. What about Cobb? Good thing about that is, Cobb is in Austin, dyno and all, so they would be able to handle every aspect of the tuning(and fine tuning) process.

I recently deleted the back muffler and replaced with some stainless steel pipe and a nice tip. I am very pleased with the sound as it gives a nice, deep somewhat loud sound but nothing too over the top. I am looking at intakes next, and i have a few questions in which i need advice. I dont want to replace the whole intake id rather just take the top off and drop in a cone filter. I am wondering if this has any positive effects as far as better MPG, sound, throttle response, and overall performance. Also by doing this would it void off any sort of warrantly since im just replacing the filter?
