First, the rear sensors malfunctioning, or perceived by the PCM to be malfunctioning, will not cause the PCM to go into "limp" mode--all it will do is fire the SES lamp.

Second, an o/r H or X-pipe will only add noise. There is little to no appreciable power gain to be had with an o/r pipe vs. a catted 2-1/2" midpipe--however if you wish to persist there is also no need for perfboard and terminal blocks.

Here's my $5 DIY MIL eliminator solution...

As to emissions testing, it depends on what state you live in, and whether they do a "load-of-crap-so-we-can-collect-some-bucks" OBDII "readiness check" or real testing.

cliffyk you know as much as I do, if he has the money he should get a tuner cause if he will make future mods a tuner will make bigger gains with more improvements. Also be less work in the long run....it's a multi-tool

Hell yeah! After opening up the exhaust I advise that a tuner should be the next "mod"--there's 7 to 12 peak HP, and 5 to 20 HP in the midrange, to be had on a dead stock new-edge (w/a 2-1/2" mid pipe and catback) --with a 93 octane tune.

Also, as you said, the tuner is a tool that will keep on giving.

Many scoff at the idea of tuning a stock car, and rather than argue the point I often keep quiet about it--then again many, many don't know what they are talking about...

tuner would be the way to go in the long run,but if funds are low and you dont wanna make it yourself ,AM has them on sale for 17.99

CliffyK said no power gains when going to an aftermarket pipe.......
I dont know about you buy my mustang has 2 precats + 4 cats = 6 cats in the way of exhaust flow. I should get more power gain than a set of headers. Im thinking about 10 hp max but thats some hella power/$ ratio. 10 HP $150 for pipe and install minus $100 for cats at scrap yard = 10 hp for $50 in about 30 minutes.

programmer works better if u plan on going with long tube headers with no cats...the extension pieces for me on the long tubes threw codes so i have my entire emissions crap disabled.

Am I just looking in the wrong spots, or does nobody sell MIL elims anymore?

Only place I found them was American Muscle, but they say they will only work for 96-04 GT's or something like that.

Anyone know if/why these MIL elims would not work for a 99 Cobra?

Thanks

Yes, they will work for a Cobra too.
