Hey guys,

I am going to be changing out my coupe mid-pipe for a 05/06 sedan mid-pipe this week. I want to grind down and punch out the studs on the flanges, and I was wondering what bolts will fit the holes.

Can anyone give a bolt size recommendation? Also, how difficult is it to punch/grind out/c clamp out the studs?

Thanks for the help, I've attached the exhaust video of my coupe mid-pipe; I will make another one for comparison with my 05/06 mid-pipe.

give me a shout if u plan on selling that 05/06 pipe!!

I had to drill out one of the bolts on my muffler when putting the middy on. The bolt snapped when I was un-doing it. I forgot what I used, may a 3\4 bolt with 2 washers and a nut. I forget. Drilling out the welded bolt wasn't too bad. Took a LOT of muscle though. Start with a smaller bit and then get bigger and bigger until it is the size of the bolt that is already welded on there. It worked great and is still working flawlessly

It's 10mmx1.25 standard, should be easy to obtain allmost any where,you'll want approx 30 mm long or so, call if can help,thx!
