do i really need to keep my airpump
Ok, prior to getting my new exhaust i read that with aftermarket exhaust i wouldnt need to keep the airpump. when i installed the new exhaust i was expecting it to replace the cat that has the pipe from the airpump in it but it did not. I have an 87 TII. So do I still need to keep it? Thanks as always

The pump creates hardly any drag on the engine and weighs less than your *girlfriends left boob. If you need to pass emissions, you have to have it and you'll foul your cat in no time without it.
Unless you have no emission testing, and no cat that needs fresh air, then remove it. There really isn't any gain though.

im not concerned about the weight savings. I just want to clean up the engine bay a bit. i may just eliminate the cat cause we dont have emissions here

No, the high flow cats designed for the FC all have the split air tube on it, which means you need the airpump. You could experiment with the $100 dollar magnaflow high flow cats, the newest ones (99,000 Series) which have supposedly heavily loaded catalyst in it. Use the biggest one available, I think it covers 7.8L engine or something like that. It might or might not last very long, (no one has tried it as far as I know, so it's experiemental) though this is what I might be planning to do. You will have to build your own flanges for it and length to what you need it to be, but it is still cheaper than high flow cats sold strictly for our cars....

I am hoping it wont overheat since it is probably the biggest one magnaflow sells.

By the way, Apexi cat-backs don't have catalytic converters (or at least not from the factory). Are you sure its not just a pre-silencer?
