Midpipe bracket question

bigbro6785 · 11-09-2012, 09:03 AM

I installed downpipes this past weekend. Apparently I didn't tighten the midpipe bracket bolt tight enough because I lost it on on the road today. I was able to go back and find the bracket but not the bolt. So my questions:
1. Is the mid pipe bracket that important? Would I be ok without it or does the exhaust need that extra support?
2. Anyone know what the size of the bolt is?

Thanks

Just a note: Don't over-tighten that bolt in reaction to your lost bolt, if it's the #12 on Enrita's RealOEM image: those will break in the top bracket if you kill them with air tools. Ask me how I know...

Ya #12 is what I need. But I'm wondering if my top bracket broke as you mentioned. I left the under tray off after my install so I could get back in this weekend and re tighten everything. I went over a huge speed bump and heard the exhaust hit...shortly after is when the bracket fell off. Guess ill have to get under there and check it out.
