Yes where the heat is more intense!

Two-way catalyst (diesel engine) [edit]
Automobile catalysts sold in the years 1990-2000 aim to convert carbon monoxide (CO) and unburnt hydrocarbons (HC) to carbon dioxide (CO2) and water, while reducing the particle mass of diesel fuel. . They do not eliminate nitrogen oxides (NOx) or reduce the amount of particles emitted.
Health risks? [Edit]
Without denying the benefits of catalytic converters, there is a lack of toxicological and ecotoxicological data on the impact of metals lost by these pots in the environment, and particularly on the health and ecological effects of derivatives (especially oxides) and metabolites of these metals.
The metals of the Platinum group, when they are present in the suspended particles, are in fact not chemically neutral (which is why they make good catalysts), and in particular in the state of ultrafine particles (less than 1 μm) or nanoparticles when their catalytic effect is doped by a very increased contact surface with equal weight of material. Some of these metals are for these reasons used as an anticancer drug (for example for an oxidized form of platinum), but not without side effects, since it is the molecule which causes hair loss in certain chemotherapy and that it is potentially higher dose carcinogen.

Would it not have been easier to do the welding part by someone who has the welding equipment and experience than to buy all the welding equipment?
Because equipping yourself with an oxy-acetylene torch requires two bottles, either purchase if small or large, it is rented per bottle $ 80 annually, in addition to refills. (Not counting the chiar of fire insurance companies when you have an acetylene store in your garage.
Unless the use is used regularly it is interesting, but if you weld once every 6 months it is not long that a guy loses his hand, even if experienced.
Normally most welds can be done with a simple electric welding machine and stainlesse rod or MIG wire. Very few handymen have a TIG system which is ideal, but relatively easy to bring the exhaust pipe to an equipped welder , which does this in no time.
