cutting exhaust pipe

[beerdog]

What is the preferred way to cut exhaust while on the car? I want clean cuts. Not sawsall cuts.

An exhaust pipe cutter.

However, don't be too critical of a sawsall, I have a very nice 2.5" sawsall guide that I used on my stainless systems.

are those things on the right cutting guides?

Yes, but they're not cheap. I paid $119 for the 2.5" guide that I bought in 2009.

That is a cool tool idea, but a bit pricey for my needs. If I am ever at your garage you will have to show it to me. Any reason a regular old pipe cutter could not be used?

No, the type of cutter in the first pic I posted should work fine on anything but 304 stainless steel.

We use zip wheels for all our stainless at work. We are not under cars though so it would make it difficult with the grinder.

Doug, what is the measured wall thickness of the stainless exhaust pipe you use? Do you use 304 or 316 because I can get either and since I buy about 5000 feet of pipe a year I can get pretty good discounts on the pipe and fittings.

16 gauge (.065") 304

Hell just wrap masking tape around where you want to cut. Sawzall, fine blade and a half round file.
