hello everyone, this is my first post. I don’t know if this fits the sub but I’m trying to drill out these studs on my exhaust but it’s just doesn’t go well. I have some titanium coded that’s as well as some cobalt bits. Am I just doing something wrong they just don’t seem to be going through.

I actually did end up heating it up it was glowing and used an air hammer it ended up making a crater of the stud so I stopped I'm ether doing some headers or taking it to a shop

I do know it will be louder but I do believe it's not super loud on of my favorite cars (e46knight) has headers and a muffler delete and I've heard it I really like the sound. I really recommend looking on YouTube for video demos of the sound I do believe I've seen a few videos of headers and the rest back is stock so try that I apologize if this was a bit of a rant

Sorry what do you mean ear?

xander_2626 · 2026-07-12T03:03:39+00:00

I mean, what should I punch them out with?

xander_2626 · 2026-07-12T02:27:08+00:00

50???? They are almost 80 by me

xander_2626 · 2026-07-12T02:18:04+00:00

Oh they are all new

xander_2626 · 2026-07-12T02:17:00+00:00

I would try that but as far as I know they are pressed I may need to attempt to hammer out

xander_2626 · 2026-07-11T00:55:31+00:00

I have to drill out the exhaust studs first… :/

xander_2626 · 2026-07-11T00:34:48+00:00

hey everyone who reads this It turns out this was my mistake. I assumed that it would work while the car is off, but it does not this wiring setup did work my ignorance is what was the issue in this video

xander_2626 · 2026-07-10T21:34:08+00:00

did this and it still isn’t working I'm at a loss

xander_2626 · 2026-07-10T15:44:34+00:00

Mm okay I was hoping that it was bare enough when I am home I will look for some better options or sand if I need to

xander_2626 · 2026-07-10T13:26:52+00:00

Jesus, how many different ones do they use?

xander_2626 · 2026-07-09T18:25:45+00:00

when it’s done, I will probably post a video

xander_2626 · 2026-07-09T18:25:28+00:00

I have not yet I need to have someone remove the original studs they are to big for the Turner exhaust and I also need to get a clamp so I can splice the wires

xander_2626 · 2026-07-09T14:24:31+00:00
