I got mine from italy via eBay. Shipping was actually quite fast. I can dig up the seller if you want.
Also installed it this week. Wow it’s great, sound and perf are improved.November 11, 2018 at 11:25 pm #2721TCParticipant
Problem is that with a non road legal exhaust system you invalidate your insurance -unless you have told the insurance company and they have approved it. With the cat delete pipe, you could use a “retro fit” catalytic converter which are small and lightweight to get the EC approval. Leo Vince make one but it doesn’t fit this pipe unfortunately.November 12, 2018 at 2:12 am #2727SSR1Participant
How long did it take to have one ?
$$?December 29, 2018 at 11:03 pm #3059
Is there any additional parts needed in the De-Cat and LEO VINCE GP ONE SLIP install, ( like different gaskets…)?
Thanks,January 3, 2019 at 12:11 am #3101QwandreeModerator
@rod, everything you need is in the leo vince box. if i recall correctly, you reuse a fastener or two from the oem cat.January 3, 2019 at 7:45 am #3102ZwillisParticipant
<p style=”text-align: left;”>You don’t need anything else. You reuse the 2 clips and gaskets from the old cat to join everything so just remove with care.</p>January 4, 2019 at 9:29 pm #3108
Here is a photo of the LV decat, I was sent for the 401, which didn’t fit, but the LV GP One fit fine.February 8, 2019 at 10:40 pm #3393
@Maxense it isn’t that bad, mainly a tiny gain in torque in low range, slight decrease in top range in both power and torque. A re-tune and a hi-flow air filter would result in decent gains, I would think. Of course, I just ordered my Lv10 and De-cat today, so I am probably making a self-serving justification LOL. Once I receive and install, I’ll do a proper soundcheck, flybys, revs, and idles vs the stock setup because as-of-now I have yet to see one. However OP’S video has convinced me enough to buy the kit.
Sorry the Leo-Vince Dyno is a screenshot, wouldn’t let me upload a PDF.February 9, 2019 at 3:24 am #3395
I ended up going with a Werkes Cat Delete for my LV – GP One and really changed the sound; a lot louder. The bike felt more peppier, (I have know way of verifying this, but the seat of my pants). I pickup an DNA air filter and will put that in and see what happens…February 9, 2019 at 3:47 am #3396
@ Rod Frost…Werkes makes a cat delete for the 701? I cant seem to find it on their page.February 9, 2019 at 7:12 am #3408
I couldn’t find a Werkes de-cat for a 701 either. I think Leo Vince makes a de-cat for a 701 ( see page 1 of this thread) but I couldn’t fine one on the web site. (just a note: the de-cat I brought from LV didn’t work for my 401). Sorry not much help.February 9, 2019 at 4:26 pm #3416
@Rod Frost i didnt look at your photo close enough. I had literally just placed my order for a leo vince link pipe and lv10 right before i saw your pic in the 701 thread and was regretting not getting the werkes bc werkes was my 1st choice. I shoulda noticed that it was a 401. No worries. Like 5 months ago i did a write up on here about 5 exhaust manufacturers and their intentions for the 701. Werkes had nothing in the pipe at that time for either the 701 or the 401.
I do like the way the pipe goes through the chassis on your 401 very clean looking.November 8, 2019 at 9:25 pm #25495Robin HoodParticipant
I have (try) to fit both LV10 and the decat pipe, i strugled to fit the decat on the only screw ( with the rubber silent block) while keeping both ends correctly attached to the adjacent pipes on both ends,
I have noticed on the official pics on LV website that they do not have the decatt fitted properly – ok they just wanted to take the picture but at least it seems it does not fit easily..
here you see the official jpg and the tilted – not fitted – tightening ring ( or what is it called , sorry):
and here is my situation:
have you struggled to get it on the screw too?
thanks for any help

It’s a bit of a struggle but it does go on eventually.November 11, 2019 at 11:03 am #25532NampusParticipant
When fitting a decat pipe I would always loosen up the front pipe on the cylinder and the silencer as well. Then fit the decat pipe in between (should be easy when everything is loose and able to move) and then gradually tighten everything again.
This prevents stress in the system which can cause cracks over time.
