I was wondering how difficult it would be to totally remove the AIR and EGR for a LT header install.

I just want it to be as simple as possible so emmisions can kiss my ***.

I have a 96 Formula and am planning to do go with Pacesetter LT's, high flow cats (not totally screwing the environment), x-pipe, and bullets dumped at the axle. Does anyone have any advise with this setup?

I am on a really tight budget and wondering if would be worth it to go with coated for an extra $100 or not. I already have my plug wires covered (crappy edelbrock headers on right now), so burnt wires isnt an issue.

 

Hey try searching for my name or pacesetter. I did an install 2 weeks ago, and they're awesome headers. I have the details from my install in one of my posts.

 

Maybe i'll simplify this a little....

How difficult is it to rip off the AIR and EGR?

&

Is ceramic coating REALLY worth it?

 

Ceramic coating, done by a reputable company, is definetely worth it. It will keep underhood temps down, and exhaust velocity up. And if you rip out your AIR, but have Cats in there all the time, your cats are gonna go out real quick. The AIR system is there to help get your cats to get up to temp real quick, and help with emissions by doing that. However, its also keeps them from breaking down quickly. So, you might be ok, but probably not if you rip out the AIR and put on cats. However, rippin out the AIR and EGR isnt that hard and really makes the engine bay look less cluttered.

 

unplug AIR pump under the engine and block off the EGR passage in the back of the intake...

couldn't take but 5 minutes at the most after the stock manifolds are out and the headers are installed...

 

you need to make a costum plate to replace the egr valve and the egr tube on the back of the intake. use the old gaskets as templates for that. not too hard, but will take prolly more then 5 min.s and, realize that the check eng. light will come on on an obdII car (96-97) but you can get a custom tune to delete those codes/functions. and, w/o the AIR pump, the cat conv. will be almost useless anyways. thats the AIR pumps function is to blow air into the exh. to heat up the cats. to make them hotter to burn the unused fuel. think of fanning a fire. it gets more intense, now you know what the AIR pump is for. I just tossed all that stuff, cats too.

 

My only concern would be a total lack of backpressure with longtubes, 3" true duals, and only bullet mufflers.

I thought that the cats would help with backpressure issues.

 

the only issue w/back press. is that it somehow helps w/low end torque. Ive heard of guys losing 15lbft in the low rpms w/cutouts. but if your eng. has a cam, it will gain alot in the mid-high rpms instead.
