Well that depends, do you live or plan on moving to anywhere with yearly inspections? If not then you'll be fine. get a straight through pipe and weld it onto your exhaust.

hold up a sec there sparky...

I'm tired of people talkin shit about the pacesetter when they don't even use one. I will admit I've never used one or seen one in person, but I've heard mixed things- everything from people hating it to people thinking it was quite good.

So don't jump to conclusions about the pacesetter just yet.

And about the cat on your 1.9, try to find it... (hint: you don't have one ;)) lol

if its a 1st gen, it seems the consensus is that the header off a 88.5-90 GT is better than any aftermarket one. Have it mediablasted and ceramic coated if its old and gross.

Well my Pacesetter header is due in tomarrow so i'll see how much trouble it is. I might even dispose of the catalytic converter. The heat shield fell of the other day so hey what do i got to lose...........

No body said any thing about the Pacesetters having the wrong firing order. It just dose'nt do what is supose to when the pulses are crashing into each other instead of helping each other down the pipe smoothly.
The 1st gen GT is correct and will increase power, mostly in the high RPM's.

When my brother had a Monte Carlo SS i remember taking the cat out and beating all the honeycomb out of it. Then we put it back in so when it was inspected it appeared normal but was really strait back. Can i do this for my escort for a hp boost or will the lack of backpressure make the motor weaker? oh... i have the 1.8

Yeah, you can run with an open cat like that. That is actually the way that people get around the annual inspections. But only if you don't have to worry about emissions. However, if the car was made with a cat, legally you must retain it. And don't get caught with one that is gutted out - that means fines.

:confused3:
The cat on my 1.9 is nestled up next to the front side of the block after a very short (power robbing) manifold. The header replaces the entire manifold + cat/downpipe back to the flex joint.

If I end up keeping my 1.9, and doing a custom exhaust... I'm going to install a racing cat after the flex pipe, followed by the longest perforated resonator I can fit underneath, finished with a discrete dogleg style muff.

If you gut your cat you're creating an open air chamber that baffles the flow of air. It's not backpressure that you want in a good exhaust system, that's an old hot rodder's myth and is pure BS. What you want is exhaust stream velocity. If the pipe is too big, the exhaust doesn't travel fast enough down it to carry any inertia.. if it's too small, you have backpressure (which is always bad) and the exhaust can't get out of the way before the next cylinder fires. It's this inertia of the exhaust stream that creates a suction effect at the exhaust ports (negative pressure) and helps to scavenge as much exhaust out of the cylinders.. improving the intake breathing.

A clean catalytic converter robs 3-5hp on most cars. A gutted one will just be louder. If you want to actually gain some power.. install a racing cat.. or take your cat to a welder who can cut the ends off and the top out.. neatly gut it.. slide a pipe inside (same diameter as the rest of the pipe) and then weld it all up neatly. I've seen this done... can't tell from looking at the car.

Once I had my headers installed 1 and a half ago…. I have only noticed good things about them… The mechanic that install them told me he matched them up perfectly.
Then he took me for a rip up the road :p doing 140km/h in a 40km.. :p hahaha the guy worked a Midas…… Ever since they were installed the car rev’d faster and higher with out and restrictions :p from the headers I had custom piping 2.5inchs all the was muffler.

Mind you its LOAD AS SH!T !!!
All in all it was worth it… now I can get the car upto 180km/h in no time.

What;s unclear to me is where you would put in a new catalytic converter if you wanted to after installing the pacesetter header.

you would put it where it is in most cars, including the escort GT... pretty much right below the shifter. the escort LX is a freak of nature having it in front of the block like that. however if your emissions/inspections are really picky you can get in trouble for moving the cat from its original position.

It's because I search.

So is there a place inder the LX shifter area where there is an indention for the catalytic. I mean is it possible to use a pacesetter header with a GT exhaust past the header and have it plug and play? If I were to have this done, I'd prefer to have any catalytic that's moved go to a new place and stil be bolt one. Seems to be I could relace the header, use the GT exhaust along with a new catalytic converter, then have something fabricated for the piece between the header and the catalyst.
