Tune after Headers only?

[-tWv-]

Hey all,



I searched around and couldn't find a straight answer, so hoping someone can help with this simple question. I have a '98 boxster and wanting to get started on some upgrades. My plan is to start on the exhaust and one of the cheaper initial upgrades is to install some long-tube headers. Since my car doesn't have the pre-cat in the header, I should be able to install these without changing the O2 sensor config at all. I am planning eventually to pair headers with intake, high flow cats, FVD brombacher exhaust, and a tune but saving money currently for those upgrades. I've read some conflicting reports online about headers requiring a tune on other cars so want some insight from anyone who has gone this route before on the 986.



I bought Manzo headers (jumped the gun a bit) and want to go ahead and install them, but want to make sure there won't be any negative impact. Can I go ahead and swap in the headers or do I need to wait and do this stuff all at once with a tune?



Thanks in advance!
