I am really having trouble with deciding on a new exhaust. I would like to get a new header so that I can change my cat but can't find a header for the tour!! I also wanted to go 2"or 2.25" pipe all the way to dual outs. Do you guys think that would flow too freely (no res 2 hi flo mufflers) on a zetec. I also don't know what type of muffler will sound good w/o rasp. I have access to a pipe bender and I can weld so I will probably do this on my own.
Thanks in advance guys

If your N/A the research ive found on the zetec says go 2.25 single exhaust. With High flow cat, flex pipe. Or if race header no cat.

I figured that if I got rid of the cat I would lose too much pressure in my exhaust.

MOTEC MOTEC MOTEC MOTEC!!

I went to the motec web site they have nothing to do to with exhaust. unless I missed something.

It is true ( I lost a lot of torque down low in the RPMS after installing the race header). But the gain in the mid to high range RPMs is great!
