My Leo Vince Slip On Exploded!

So I have a 2006 GSXR 600 that I bought new from Bike World last summer. It already had a Leo Vince slip on carbon exhaust on it, part of a special promotion Leo Vince was doing with Bike World. I was like, sweet, it already has an aftermarket can on it so I don't look like a dork with a stock exhaust. Total poser!

Anyway, for the past few months, people have been remarking about what a beast my bike sounds like. People have been impressed by its virile growl, more so than before.

When I was at Buttonwillow with my bike for the races a few weeks ago (I trailered my bike down there with CityBikeMike and DucatiHoney to ride Highway 58 and then watch the races on Sunday), some guy, I don't recall who, warned me about my Leo Vince slip on. "If you do a lot of track days on that thing," he said, "be careful, that pipe isn't great for intense sport riding, mine blew a hole in itself." I was so overwhelmed by the number of people and things going on at the races that I didn't have enough mental energy to process this information at the time.

Anyway, when I was at Infineon for a track day on April 8, I kept feeling myself scraping something on my right side (lots of right turns on that track, and the can is on the right side as well and has scraped before). I didn't think it was my knee dragging, or even my toe, so I gave the Leo Vince a good once over. Much to my surprise and dismay, the can had a three inch long gash in the bottom of it, and it was definitely NOT from scraping, it was in a place where it would have been impossible for that part of the can to scrape anywhere. No wonder my little gsxr's been sounding like a GP bike lately!

Has anyone else had this problem? If so, what did you do to resolve it? When I'm better (recovering from back surgery) I'll pay a little visit to Bike World and see what they recommend. Any thoughts?

I :leghump CityBikeMike, screw getting lessons on track riding, I need some lessons on how to get all the Ladies on Barf :laughing :wow
 
BTW contact DeathB4Mullets, I believe he works with LeoVince and would bet he can take care of you.

Not sure what that dude at the races was talking about, because it seems like all the fast bikes at the track all run leo vince. I see them all over the place at the track and doubt that they have a mass problem of imploding with track use.

If you thought something was scraping, you felt it, and then looked under your bike and see your muffler all scraped up, I'd bet it IS your muffler scraping on the ground even if you think it couldn't hit there, wtf else could it be? Is it possible that the can hit the ground and then twisted? Either way a "gash" comes from hitting something.
 
Willis can help you Christie. Leo Vince is a good company.
 
It could be a case of needing to be repacked. you did mention that it seemed to get louder before it blew?? once the packing material is gone the exhaust heat and exhaust pulses start to attack the canister material.

here is another brand of exhaust that I had the same problem with, unfortunatly I could not repack this can because it was riveted and GLUED together on the ends.

Exploding != imploding.

A gash can be caused by internal presssure pulses flexing metal outwards and splitting it due to repeated fexion causing metal fatigue and failure. See hwy1&17's post above.

All this is guessing anyway. Christie, post up t3h pics (and maybe one or 2 of the exhaust, also :laughing) and we'll be able to tell you more about what's going on.
 
Well if you want to get all Barf and techinical;
gash1 /gæʃ/ Pronunciation Key - Show Spelled Pronunciation[gash] Pronunciation Key - Show IPA Pronunciation
–noun
1. a long, deep wound or cut; slash.
2. Slang: Vulgar.
a. the vagina.
b. Disparaging and Offensive, a woman considered as a sex object.
–verb (used with object)
3. to make a long, deep cut in; slash.

A gash infers that the cut was made from the outside, if it truly exploded from the inside you would have something along the lines of a "split" or "burst".... or "cunt" ....wait.......:teeth :teeth

Exactly why pics would be best. :thumbup

So come on Christie, post up pics of t3h gash! :ducks and runs for cover :laughing
 
I believe Christie mentioned it is a Carbon Fiber. CF is great looking stuff but if you are serious about trackday riding it really is not the best material. The sun degrades it, it explodes on crashing, and it does not heat cycle well. Particularly on V twins for some reason. My CF akro blew up in short order on the track. If you have serious bucks and can replace the cannister often it is the way to go, but if you want something that lasts get Ti, Alu or SS, not CF.
 
Let us know if you can warranty it, I have the same pipe in carbon also.
 
Is DeathB4Mullets Willis? I will contact him and ask. Unfortunately I can't get any pictures of it right now, but it looks like any gash in a carbon fiber pipe would. Kind of ragged.

I'd prefer to swap it out for a full exhaust, I think, probably one that is not carbon fiber, although the gsxr is likely going to become a street bike, no longer a track bike. Any suggestions for cool full exhausts?

Thank you so much everyone for the advice. I'm sorry, but I won't be repaying you with pictures of the other gash. Ew! :laughing
 
You probably can contact Will directly or ask the dealer you bought the exhaust from to help you out. I just sold one of my neighbors a full system for his new GSXR750 and had to talk him out of the "pretty carbon" because it's just not the ideal solution for the racetrack. I go for the ti cans every time! I have never had a problem with them and I also know LV stand behind their product.

Since yours is already busted up, I would strongly suggest you try to work out a sort of "trade-in" deal for a ti full system if you're using the bike mostly at the track. I've never been a huge fan of the noisemakers (aka slip-ons) at the track... ;)

I have a stock muffler that you can have if you want it. Why do you need a $2000 full Ti exhaust system for the street?

They're not quite that expensive, even the full ti Corsa systems (which btw you do NOT want to buy unless you have a built motor that can benefit from the bigger tubing on the Corsa models). A stainless header with ti can is not very expensive - I seem to remember they're just over a grand, especially if you know the right people... :teeth
 
I have the same setup, albeit the titanium slip-on.
I believe that if you tuck the can far enough under the bike it can rub against the shock linkage bolt. Could this have created the gash? Leo recommends mounting the bolt from the other side of the linkage giving slightly more space between it and the exhaust.

To look cool at the bux, yo. Duh!
 
Hi Christie.

Just give me a call here at the office. We can get you taken care of, no problem. BTW...We will most likely swap you out for a titanium slip-on, as it is a much better material for track-day/racing applications.

In most cases, the scraping happens when the mid-pipe is not pointed perfectly, with the can tucked up and away. I have been at the track, and fixed these for people, and sent them back out, with no scraping!
