Broken bolts on stock downpipe

[dvn]

I installed my BNR downpipe today and when removing the bolts from the stock downpipe to midpipe, two of them snapped off. Anyone else run into this? Any idea if a muffler shop could replace the studs? I'd like to be able to reinstall it if needed.

yep

Happens alot,

I just went to auto zone and got 3 bolts and nuts to remount. Some people say get exhaust grade ones to hold up to heat. I just got regular ones. Size and thread doesnt matter just make sure the bolt fits through and has thread on other side to bite.

But how did you remove the broken studs from the stock DP? I believe they are pressed in, no? I will have to get them out somehow in order to remount it later.

If they are pressed in like you say, beat them out with a hammer and punch. 1 good shot with a 24oz+ hammer should do the trick. I haven't touched mine so I'm not sure how they are mounted. If they are welded you will need to cut the weld using a die grinder or dremel.

Thanks. I'll take a closer look at them and give it a shot.

o ya

ya just take the dp off, put it on your work bench and pound the **** outa them till they come out, they are just in there good from being heated and cooled. Dont worry about damaging tht little heat shiled thing you can bend it back easily

I'm going to assume no one owns a press?

Out of 8 friends and family who are mechanics, none of us have a press at home. We do at our jobs. The OP asked a question a seasoned mechanic would have figured out on their own (OP don't take any offense, we all started somewhere). That tells me he probably doesn't have a press, or acces to one. Besides why waste time setting up the press to knock out 2 studs when a hammer can do he job in no time.

Yeah, it only took me two good taps with a claw hammer on each stud. They break so easily, I'm 99% certain they're not meant to be reused. Go ahead and replace all 3 because the third one will probably fail on the road if you try to reuse it.

Wow snippy today!

Or, yesterday rather.

I didn't read Blue hedgehog's comment as snippy. It's just a thorough response to what could be interpreted as an arrogant comment on your part.

No. Not trying to be snippy. Sorry if it sounded that way. I was just trying to say most people don't have a press at home.

Claw hammer?!?! Why I oughta...! Claw hammers are for carpenters!!
J/K I'm one of those "seasoned mechanics" spoken of earlier. OK, actually an aerospace tech.

Mine broke and I replaced them with stainless steel #8 1.25x40mm from home depot. I took the heatshield off the cat before hammering. The old ones come out quickly

Thanks guys.
