Massive exhaust failure
Ok so today I was leaving work and decided to have some fun with a 750 suzuki. I was playing with him as we got on the highway I let him gain a few car lengths while pacing before dropping gear and actually getting on it to play cat and mouse with him.
Hit the accelerator hard and heard a pop and the bike got A LOT louder. Instantly shut the bike down.
When I redid the exhaust the one thing I didn't change was the #6 sleeves (part number 18392-MG7-750 I believe) because they were still fairly new from the previous owner.
After pulling the exhaust/ header back apart I found that the one coming off the rear cylinder failed and injested it's self into my pipe.
Temp fix until the new sleeves come in was aluminum tape with a small bead of gasket maker. The leak is now temp sealed up.
Point of the story: I looked like a fool as a 750 stroked me over a cheap part and this is my "noob mistake" of the week. Hahaha

Not true. I lead my friend through an 1/8th mile. He is on a 2004 gsxr750 with Micron and PC. My gearing is supershort though 
I also trounced a well modded cbr600rr in about a 1/4 mile. Left him for dead at the top end of 2nd.
These superhawks sure are fun...

Yes it was a gsx-r but the rider is new to motorcycles. So new in fact that he uses the clutch to shift instead of sweet spotting it.
Crux are they lead? What I pulled off looked to be graphite based mesh.

You have been warned about the endline rotary girder.

I will have to drop the bike off the Callahan breaks and have Tommy take a look at it next time I need doc to recharge my Flux capictor.
And it's easy to keep up with a rider that's scared to open his throttle during 5 o'clock traffic no matter what bike he is on.

I had to replace mine a few weeks ago (when the previous owners method of using a gasket sealant in place of the required piece failed after almost 2+ years having the bike myself)
Luckily being in Los Angeles, there were multiple dealers that had it in stock locally so I was able to get some that day

Funny enough I had the camera running and you can hopefully hear the sound difference, I noticed instantly, it is right after I make the left turn after waiting awhile

Wasn't a carb fart. Literally the pipe popped off the rear jugs header pipe where it ties back into the main pipe to the exhausts. The seal there shelled itself out and allowed it to drop. After that I shut the bike down.

Clamp could not have been secure or the gasket was extremely damaged to begin with. This gasket is captive in the pipe under pressure from the clamp.

I believe the gasket was damaged the last time I put the exhausts back on. Found remnants of it in the baffles in the exhaust (the few that are there). Figured it caused back pressure through the line and it gave at the weakest point which explains the loud pop I heard. The clamp was a till tight but will be replacing it too over the winter.
