Cracked exhaust

[Skurge]

So the exhaust on our 2003 Mazda B2600 pickup cracked right after the catalytic converter I think it is. How would be the best way to repair it? Or should it be replaced entirely?

Total n00b here btw.

You mean the exhust pipe?

If its a small crack it can be welded if its large or cracked due to rust/damage then just cut out and replace with new pipe.

Are you doing the repair or is someone else?

If it's small I'd gouge-grind out the entire crack, plus 1/2" on either end, then re-weld it.

If the crack is big and gaping I'd cut out the pipe section and weld in a new one (like Marlin suggests) or cut out the bad stuff and do a scab weld.

Im getting someone else to do it. Its a small crack. The 1st idea sounds best to me.

Another question, Now as soon as I heard to odd sound I parked the car, but what are the effects of a cracked exhaust pipe?

You'll just leak exhaust under the vehicle and it'll be a bit louder. Depending on the location you may get exhaust fumes inside. It'll run fine.

This will be your biggest problem. Start carrying a 12 gauge and improve the gene pool as opportunities present themselves.

my exhaust is busted right at the muffler, so i get them all the time. usually it will be kids in riced out hondas/ acuras/ nissans tho. and i dont want to get rid of them, they are a good source of entertainment!

ive been trying to get lift time at my friends shop since i bought the car to get it welded up, but hes been so busy i havent bugged him much to do it. im trying again tomorrow, but i hear we are going to lift a 4runner. probably not have time again.
