exhaust

Hi everyone, I have encountered a problem while fitting a black widow system to my 2024 cbr650r. I’ve just noticed that the bike has 2 sensors going into the exhaust. The o2 sensor on the right side of the bike that goes into the pipe but there’s another sensor on the left side going into the...

I know titanium is supposed to blue but I noticed some brownish spots on the ends of the muffler and I was wondering if that’s normal? Google doesn’t seem to tell me much about it turning anything other than blue…

Hi all! I'd like to fit my bike with a low level BlackWidow short can (200mm), I have had a call with them to understand the legality of it all and since it's my first bike in the country I don't really know what the MOT test for it looks like. The company said that their silencers don't BSAU...

Hi all, Just bought a new exhaust for my 2022 CBR650R and I was thinking of installing it myself. The only issue I have is the guide does not have the torque specs I need to attach the headers to the block. Is it safe to say that the standard specs are correct for this (22nm) or because it is...

Reinstalling my akra exhaust and while removing the stock exhaust I have somehow managed to actually remove one of the mounting studs (92900-08022-3E) instead of just the the hex nut. Attempted to bolt it back in and this time just try to remove only the nut but no luck, the nut seems pretty...

Hi all! I am new to the world of aftermarket parts, and I would like to install a Black Widow exhaust to my CB650R 2019. Apart from noticing the insurer and make sure the exhaust is street legal, do I need to do else? I am quite confused on wheater there are better legal exhausts for this...

Hi everyone I own a CB650R 2023 and it’s time to upgrade my boy with an aftermarket silencer. 1 - What do you think of akrapovic silencers ? 2 - Does I need to do a remap after the new aftermarket exhaust is installed ? Thanks and lookin forward for your help.

Hi, I installed my exhaust system today with new gaskets. After torquing the bolts to the engine head, I noticed that exhaustpipe1-3 looked good (I can see the gasket is crushed underneath and overneath), but I'm unsure about 4 and whether I need to redo it. It seems that the exhaust pipe is a...

Hi All, First post here so apologies if I sound like a noob. I have tried to take the stock exhaust of my 2014 CB650F, the outer two headers are loose and free however the middle two are stuck good. No amount of wiggling is helping, no amount of persuasion with a mallet is helping and I even...

Just bought a 2014 CBR650F and it came with this exhaust, thought it was a Mivv exhaust system but the end caps are slotted in mine. Anyone recognize this exhaust? Thank you in advance Adam

Hi. I'm going to install a MiVV GP Pro system and I have some questions. I've ordered new exhaust gaskets. What I'm wondering is how to put them on. I need some advice on how to keep the gaskets in place. Question 1 Can I use Firegum exhaust assembly paste on the gasket instead of copper paste...

So I brought my bike to a shop I’m pretty close with and they were helping/showing me how to install my full Akra correctly but I noticed a couple things that seemed off to me… 1. They used Blue loctite (which is fine I think just no video I’ve seen uses it) 2. When using the torque wrench I...

I want to get my girlfriend a titanium exhaust for Christmas for her bike which she just got, But I want to make it. I haven't welded titanium but I've welded plenty of stainless steel at my job I just got. I just have questions as for the process of making the exhaust if anyone would be able...

Can anyone confirm the size in diameter of the exhaust gasket? I beleive this is the part number. 18291-MN4-920 I'm having no luck finding it and the shop wants them off to check. I'd like to have the parts ready to go so I can install the exhaust not have to stop halfway through to drive...

Hi just thought I would post a pic of my 2014 cb650f with new full titanium vandemon exhaust system. Awesome quality and nice deep sound without being obnoxiously loud. Opinions on looks?

Hi Cellmates, it has been over 4 years that I fitted Akra and I used to love the NO BAFFLE noise. This season however it became loud enough to me to put the baffle back in. Now even with Baffle in, It's loud. I know pipes will get loud over time but just wanted to confirm if its the case for...

I purchased a '21 CBR650R that came with a full Akrapovic exhaust on it and decided to swap it out for the stock exhaust as I'm personally a fan of the stock sound. However, after installing the stock exhaust and tightening the header bolts as much as I could, it sounds as though there is a...

Hi all, struggle to find info an this. Got a bike with a full akrapovic (race) system. After running the bike for a few months I've had to change back to a standard exhaust. It was way to loud leaving for work at 4/5am with my garage under little ones room. Do I need to get anything done to the...

Hi all, first post so be kind! Ha. I need a standard exhaust for my bike. Bikes been fitted with an akrapovic race system and it's just too loud leaving for work at 5am. My question is. My bikes a cb650f 2018, there are a few systems on eBay that fit a cb650f and cbr650f. Knowing they use the...
