It's a zetec. Is that extra .25hp worth the cost?




being as that i got it mandrel bent for free (my vocational school as a bender) yeah it was definatly worth it espically since i plan on putting on a turbo.



Well dang, you coulda dun mine while you were at it.




the instructor even got the tubing for dirt cheap.

i paid $35 for 16Ft of 2.5" and 8Ft of 1 3/4"

i also got it put on for free too so all in all i paid less than fifty bucks for an exhaust

All I'm really looking for now is a supplier and part number for the flange. I'm going with 2.25" crush bent pipe to the back with the muffler I have, and if it's loud, i'll go from there and throw a resonator in the middle.

Even on a mildly modified Zetec, putting on a mandrel bent exhaust over a crush bent exhaust of the same size can show a 3-4 HP gain on the dyno. The more modified it is, the bigger the power gain is.

Just FYI, I decided on crush bending some 2.25" pipe and welding my muffler on. It was what I could afford to do, and it's sitting in my garage right now. If it's too loud I'll throw a resonator in the middle somewhere.

The next step is to take my factory system off, I'm expecting that to be a [censored] with the rusty, seized up flange bolts. If they're too stuck I guess I'll try heating them up.

By the way thanks for all the help this past week or two.

bring your stock one to a machine shop and have them make you one for 2.25" piping.

if you wanna keep this thing quiet and rasp free you're gonna need a resonator AND a muffler...not one or the other or you will get rasp in the upper rpms.
