So I was tightening up my exhaust and crap when I noticed that there is no bung for the hose from the smog pump. So, I have nothing going to that and I have the bottom of the canister plugged off. The only thing the pump is doing is pushing air threw my heads right? Can I just take off all the hose and cap off the ends? I don't have money to buy a shorter belt, can i just run the pump without the hose for now? Do you think this is messing with my performance at all?

Does your BBK pipe have cats? If it does, I would call them and see if they require the air from the pump for them to function properly. The factory h pipe may fail without the air pump.

All the pump does is pump some air. If you remove the pump, you might gain 1 or 2 hp. Aslong as you cap off all the necessary vacuum lines for the emissions stuff, your not doing any harm.

You can just bypass the smog pump and leave everything in place. Just buy a shorter belt. Make sure you plug any holes that are created. If you are going to take all the hoses and pipes off, why not just take the pump also? You don't need an eliminator kit. If you are going to take all the pipes off, don't leave the pump connected.

Then just leave it until you get a shorter belt. If you run the pump you will be pumping a bunch of air into the engine compartment. It will probably make noise too. When the hose that connects the smog pipe to the h-pipe came loose and was hanging on my car you could hear the air. It made a whirling noise when the car revved.

It won't hurt anything.. think about it, all it does is pump a little air.. hence the name, air pump. Don't worry about it, leave it unhooked as you wish, you won't hut a thing.

What he meant was he wanted to leave it hooked up and functional, but take off the hoses that connect to it. Therefore air would just be blowing into the engine compartment. The chances of it blowing a vacuum line off are not bad, but it will sound like junk.

Yep, the guy before me made it that I couldn't hook up the smog pump to the exhaust. So it made a "brrr" sound from under the car...annoying as hell. This was just a idle also.

He made his own exhaust from the headers back. I don't have a H/X pipe on my car just two mufflers. I had a metal tube coming from the smog pump that was supposed to plug into where an X/H pipe would be, and when the car would run this is where the noise would come from. It was closed a little bit, but that could have also been from a wrench or something.
Oh another thing the guy messed up on was he only hooked up one o2 sensor.

What a mess. Are you going to get a new exhaust? Do you have any pictures?
