hey guys so today i went to put on my skunk2 catback on my 07 si and i went to take out the three bolts that are on the cat to the exhaust bracket and they wont come off. i heated them up, tried to drill them out i couldnt get them out for ****. can anyone please help me?????

 

pb blaster...spray it on...let it sit for 1 min. and it will come off easily

 

i tried that too still didnt come off.

 

use wd40 and let it site there for a minute and use a hammer to knock em out

 

Just leave them there. I left them there when I installed my Vibrant catback without any problems.

 

the nuts come off. the "bolts" are actually studs and are welded in there.

 

the video skunk 2 released for the megapower catback looks like they left the nuts on there
