DIY exhaust. not howto, will it be better?

not on these exact pipes. but stock iron ones. for any car i guess.
anyway, cut the old factory pipes off an weld just slightly larger ones on the (bolt on piece?) and weld on inside, then grind and smooth. then when your at (circled blue section in pic) drill a hole for the o2 sensor and use a nut that has the same threading as your o2. and re-use the old hangers and fastners,(green selection)

if the pipes were slightly larger, (all the way to your muffler) this would increase performance. correct?

lets say you used this info just to make a turbo setup, and not to the muffler.
idk, lets say a geo metro?

short answer yes, but you won't be able to use that header with a turbo setup.

I like the fact you also used light blue as a color and didnt explain what it means.

Also why did you choose a d series header as you example. I'm pretty sure its a d series header

[jumpncrash]

No he did, he said the light blue was where he would re-weld a nut that a stock O2 sensor would screw into

I didnt bother reading the post past the first line.

[jdamion]

at least you read, btw i know thats not the right setup for a turbo. lol. i'm not that dumb. it might be for a 1990 geo metro hatch. idk yet. i dont know how to weld. i got to take the class

[Kitty]

But they have turbo manifolds for the metro.

lmfao, you're going to turbo a geo metro?

I think he should use wood for a cat back exhaust....it'll match the rear air spoiler.
