It's all welded from the exhaust manifold downpipe to the rear??? If you add a header, you'll have to cut somewhere, most header have a downpipe (some longer than other). On my car I asked the guy at the muffler shop to put a flange after the downpipe and before the cat, so it will be easier to remove it later...

Exactly what he said. Since it's all welded up your going to end up cutting somewhere. This also a reason why people wait and do it all in 1 shot to save from paying labor charges more than necessary.

If they are actual professionals, they can do anything to your exhaust system as far as fabricating.
