Demon bolts
Just got my Z and has 100 miles on it. I know I will replace the cat with tp or hfc eventually. Do you think is a good idea to start removing the bolts and replace it with normal bolts while is still new?

Chances are they're already stuck on. You'll have to break them regardless.

I did mine at 250 miles with no issues at all. Invest in a set of Grip-tite sockets and a good sized breaker bar for leverage and spray the bolts good with WD-40 or PB Blaster.

There are some damned good bolt breakers out there. I've seen decent results with PB Blaster and WD40. I say that because a friend of mine has this other can which made both the products look terrible.

Did a little penetrating spray search on the internet, while practicing my Google-Fu.
Turns out it's Liquid Wrench. Seemed to work better than either PB Blaster or WD40 (which is terrible for breaking bolts in general, if you ask me). If you can find PB Blaster or Liquid Wrench or WD40, choose either of the two over WD40. I also found a forum post that quoted a magazine, which showed an interesting result: Best Penetrating Oil Test - Surprise Winner For those of you who are TL;DR: A 1:1 ratio mix of automatic tranny fluid and acetone was shown to make breaking the bolt much easier; only a tenth of the torque was needed to break the bolt. Also if you're strapped for penetrating oil (say, if you're like my friend and I, and need more penetrating oil but it's 3 am and the local walmart/major-retail-chain-open-24-hrs is sold out for some odd reason), highly carbonated drinks also work. Not nearly as well as WD40, but much better than nothing else. Vinegar also works, although it's kind of a waste. There's also that new fangled naturally based (soy) lubricants which are apparently just as effective/more effective while being environmentally friendly. The best part is that they don't smell like nerve gas.

Nice find on the ATF mix. Although I don't know why they chose acetone to thin it, that stuff evaporates too damn quick... mineral spirits (paint thinner) would've been a more practical choice IMHO. |

I'm sure you'd know just how well Ron Jeremy penetrates! Well, the faster it evaporates, the faster you can start turning on the bolt. I guess you would have to be pretty generous and try to use a piston oiler or similar to try to get a direct stream onto the bolt. This is, of course, given you don't splash any on yourself. I once saw a demonstration of a styrofoam head being placed into acetone.

Acetone is one of the safer industrial solvents, no issues with getting it on your skin. The other problem with acetone, though, is that it eats certain plastics...

I'm not sure on what concentration of acetone was used for the penetrant mix. I'd imagine with a percentage high enough, you'd make it difficult to use unless you were in a very well ventilated area.

This is not totally accurate. I work with the stuff for my job and i can tell you that excessive amounts of contact with the skin can make you sick. Small amounts aren't gonna hurt you but continue splashing it on yourself and you're gonna get sick.

I concede the point; but for general use around the home workshop it's pretty safe. I believe the main issue with acetone is not the acetone itself, but the fact that it cleans your skin a bit too well, and increases the skin's permeability to other chemicals which can be harmful.

When the time comes to remove stock cats, just be prepared to snap off the demon bolts with a good 14mm bolt remover.
Work on those first, and the rest of the install is a walk in the park.
