OK here is the final answer from Megan Racing....
Hi,
Thank you for your email. The headers are the first generation we made
for the TC, we are trying to make something for the TC community. As you
know, the new TC factory header got a built-in catalytic converter, which
made all aftermarket header manufactures real real hard to produce an
aftermarket header for the TC. It is because most headers that you can find
on the market, they do not have cat converter inside the headers. We did
make a similar cat inside the header to reduce the chance to have the CEL to
come on, thats so far the best we could do. None of the other header makers
now is able to make a header like ours, the other companies that making the
TC headers now do not include any cat or anything to reduce the chance to
avoid the CEL comes on. So I hope you to understand that we are trying to
do something for the TCs and we will improve whichever products that are not
doing right. This is for the first generation, so for sure 2nd generation
will release anytime in the future. We are trying to control the CEL to
stay off all the time. We already have couple plans now, and we are working
on it, and we might even give away free 2nd generation headers for those of
you need to replace it. So please don't get upset and hand on there.
Solutions:
1. Look for different materials to replace the current ceramic cats we made
inside the header, a long lasting one and is able to keep the CEL off.
2. 2. Work on the S pipe after the header, that’s what other people suggest.
3. Discontinue this product just because there is no way to make a good
header and keep the CEL off.
