Why are my stock exhaust bolts welded on? (see pics)
Hey,
So this one racked my brain for a while. I ordered a Megan Racing y-pipeback exhaust for my G37X Sedan to install, figured it should be pretty straightforward. boy was I wrong!
Background: car has FI RHFCs, K&N Short Tube Intakes, Stereo upgrades,
Take a look at the photos below where the Y-pipe meets the exhaust, those bolts are freaking welded on?!?!
I tried to remove them with a 14MM wrench, breaker bar, pb blaster, MAPP torch, didn't really get anywhere, used my 3 air tools, stripped the bolts ultimately. After using my vice grip and a hammer, got nowhere again, decided to take a hacksaw and cut off the bolt. Still there was 1/8" of an inch of bolt left, so i took my dremel- metal cutter and cut this off, passenger side, closer to the exahust.
After this, i took a punch and a hammer and started to hit the bolt to loosen it up or jar it free, but the welded bolt is not moving.
What do you guys believe i should do? I bought some cobalt drill bits to potentially drill it out, and i will likely end up cutting off the other side which is somehow welded on. The megan racing exhaust came with new hardware, so will be fine.
Still puzzled why the y-pipe bolt is welded to the connector??? Any ideas?

Advice, get some Cobalt bits and drill it out if the dremel can't get the job done?

That is definitely not stock. Good luck!
I accidentally stripped a nut holding the muffler on and used an angle grinder grind away the stock round bolt head. That bolt is pressed into place and has a round head on the bolt, after grinding the head off I beat the hell out of the end of the bolt until the head pushed out.
Looking back grinding the head off probably did nothing for me. I didn't realize it was pressed into place.

Get a small right angle die grinder at Harbor Freight, if you have an air compressor, if not get one of those too. Both are invaluable for me. Can also use to easily slot your toe arm mounts too.
