some exhaust based questions

[tigercrazy718]

so i used the search function and came up with more questions than answers ive been thinking about doing long tube headers (therefore eliminating my cats) but i read one post on here that said you cant do long tube headers with a turbo, which is what i eventually want to do. i couldnt find anything to validate this claim, so can anyone do this for me? and also do our cars even sound good without cats? right now i have magnaflow dual catbacks for reference thanks!

With a turbo you do need special exhaust plumbing to conect the turbo in line with both sides of the exhaust (unless you do a twin turbo install, but that's an entirely different story!) in a position as close as possible to the intake side of the engine, so long tube headers wouldn't work for a turbo. If you are really set on FI, an S/C would be a better way to go-more choices for the Mustang, no turbo lag, and it would be compatible with long tube headers.
Don't know what the rules are in your jurisdiction, but here where I live in VA that kind of a set up would not pass the emissions inspection test and there are other issue with eliminating the cats-I don't know if the Mustang PCM can be "fooled" on this issue and you might run into driveability issues if the PCM doesn't have the feedback loop from the cat to adjust the A/F ratio as needed. Also, a S/C is usually emissions compatible which is good for drivability and pollution.

thanks for the info
im pretty set on the turbo tho so ill probably leave headers out of the mix until i actually start saving up for the turbo
