Before I owned my 325iS, it belonged to a friend of mine. He had bought a new mid-pipe for it and expected it to be a bolt-on; it wasn't. The mid-pipe bolted to the headers, but had to be welded to the muffer flow tubes.
If you have a welder, you should have no issues. though.
I wouldn't do it yourself....there are a lot of fitting problems with the UUC...I've had it rewelded on twice by my mech and it still raddles like a whore.

Hey Deloriant,
My exhast started rattling a few months back and I found out it was the heat sheild on one of the catalytic converters. There are a few spot welds that hold them on and one of them broke loose. I just bought a couple of large hose clamps (same ones used for dyer exhausts) and clamped around the entire converter. One wasn't long enough, so I put two of them together.
Not sure if your rattle may be the same, but it's definitely worth looking into.
Im not doing my UUC til the spring, but from previous experience with exhausts systems don't think this is gonna be a 20 minute job. Depending on how long your exhaust has been on there, those bolts have a habit of seizing up and can be quite a pain to get off.
I just dropped a new exhaust in my little bro's G/F del sol last week. I had to cut off the bolt heads then tap out the remaining bolt to get them all the way out. Then for some strange reason there is no lip to rest the sealing gasket on these VTEC cars. Since I was doing it on my own, I had to grease the hell out of the gasket to get it stick in place while I slid the pipes back on.
Dunno, I've seen the DIY for bimmers and they talk about dropping those 4 bolts that hold the exaust to the cat like its a cake walk. I would be prepared for the worst.
I guess if your gonna do it yourself, soak the bolts overnight in a good nutz off. Then have your torch handy to head to bolts when you go to pull them off.
To do list:
Suspension--- researching
UUC System U TDM- 3/05
M50 manifold converstion 3/05
off to the tuning shop for custom software 4/05
Cams/lightened flywheel, throttlebody........ well lets see what happens

Yes the UUC is a bolt on.
Yeah, I know about this. The first few times I took the car in to check out the rattling, they said it was the headshield, so they retightened it. Well, low and behold, the sound came back, and then they said it was the exhaust. So they rewelded that, sound went away. WELL, now the sound is back! lol
