Covering split air pipe?
Hello,

If you're removing the cat, then the entire secondary air injection system is redundant and can be removed. That includes the air pump, air control valve, silencer and split air pipe.

Sorry, cant remove the emissions. I plan on swapping the downpipe/presilencer for the stock system once a year... either that, or having a cat built to properly suit the system.
Are there cats that you can buy for the racingbeat exhaust system?
Thanks

I have an N/a but you can just leave the hole as is and then put it back in for testing. I have had no trouble like this since I got my exhaust.

I made mine (before I realised I didn't need it) from a small scrap off 3mm aluminium. Trace the shape of the flange onto a piece of paper to use as a template, cut it out with a hacksaw, drill two holes and slap it on. Cakewalk.

I know, but without a cat the whole lot's redundant and can be removed. If the air pump and ACV are removed you don't actually need to block the split air pipe hole.

Unless of course, that hole only leads to what has already been blocked off by the ACV plate, in which case I guess I wouldn't need it. Come to think of it, that is more likely how it works.

If you are taking the exhaust out, the split air pipe will come out with it. I don't see where your issue is then.

Why not just take off the split air pipe too? It isnt any more work to add onto removing/installing your cat. Block off the split air port on the intake manifold and when emissions time comes, put everything back on.

Doesn't that involve removing the ACV?
I guess my question is, could i just leave the split air pipe hanging there? or do i have to make a cover plate for it to block it off?
