if you're going turbo, you want 3" from the turbo all the way back. no questions asked. preferably no cat, absolutely no resonator, and straight through mufflers (ex: dynomax race bullets).
On turbo cars, back pressure is the biggest enemy. You want that exhaust to FLOW.
Generally, it's like this on all 1.8's. My escort and my friend's miata both noticed CONSIDERABLE increases in power running a straight header.
