This is want happen to my right side muffler,



at 121k on the clock, this happen. Just driving along when all of a sudden the Z changed sound (sounding like it had side pipes and cheery bomb mufflers) I check under the car (being low) didn't see any thing, so I thought it was the gasket at the muffler connect that failed ad or the connection loosened. I drove about 20 miles home.

This cause the wiring, wheel well liner in the right side fender and the foam bumper block to melt. Some how it didn't do any damage to the exterior body. Some what lucky for me.

It may be worth checking your ti mufflers if you have over 50k and have been tracking.

Wow!! Must have had a weak spot from the factory IMO. 121K isn't that high.

Well that sucks...went from mild to wild quickly... Time for an upgrade I suppose.

Something blew right thru that thing....I wonder if it's pieces from the catalytic converters

wow what the heck

It could have been hit from the outside and punctured.

I'v had a Borla system that I had custom tips made (never liked the coffee can tips)

that I have put on for now (nice to have a back-up) until I can find a right side TI. As for something blowing thru (cat explode), no. The cats are still there all in one peace. Like I said, I don't think it's just the milage, I have used (not abused) the Z for want it was built, Autocross, Track, and a season at Bonneville (to lock in my 150 lic.) Oh, and a month in Europe touring. Did you know that the trans will go in to overheat after 10 min of 140+, gas milage goes to hell too.

I'm guessing it's just like a hot section in a Jet engine, after so many heat cycles the metal fatigues and crack...

I think you nailed it right there, sir!

FASTFATBOY

I bet it had a bad baffle in it it for a while that caused this. Aren't these mufflers known for stopping up internally?

Moto One

Just from looking inside there is no internal damage, the cracks/hole are in the first open chamber, and is right inline with the inlet.

That looks like road debris came up and hit the muffler. I highly doubt it was heat or internal failure related.

I don't think there is an upgrade for the stock lightweight trick as hell Ti mufflers. Get another set, do the bypass mod and enjoy. Everything else is heavier and just plain old SS.

Moto One

Yea, I don't think that where the hole is that any thing could get up in there to do that kind of damage. There is plenty of what looks like heat distortion on the end plate.



Right now I have my old T-1 system on


(plenty of noise for sure and very basic in the looks department, and I kinda like that) but I just answered a PM from Jon about replacing the Ti's

I think you'd be surprised at what can get kicked up off the tire and where those impacts can take place. I'd lay money that was road debris impact supported by the shape of the failure.

In fact it may have been damaged long earlier and fatigue vibration then caused it to fail more significantly as the crack spread.

Moto One

Maybe, ether way it's still a hole.

Mark

Very true! Good luck with the fix!

Ask a professional welder if that material can be welded, I'm sure given the right heat with the right rods it can be repaired.

You can't weld rust like on a normal muffler, but I'm sure if the material is solid it can be repaired somehow.
