Great video! Do you think it is a problem if you remove one db-killer?

Hello, congrats, very nicely done. Quick question, which kind of drill bit did you used (what material) ? Just a standard metal drill ? I am not used to drill in carbon. Thanks

@gravelroadslovenia

2 жыл бұрын

Just a normal drill for metal/wood. I do suggest you make a smaller hole first with a smaller drill and go for the bigger one. By doing so it will be easier to drill the hole more precisely. However, drilling makes the finish of the hole a bit rough, therefore I suggested to finish it up with dermal to make things nice and smooth. Just be careful not to increase the size of the hole with it too much. Drilling carbon is nothing special. Its thin so its like drilling though a sheet of metal. The residue is fine black dust from the resin and the carbon fibers. If you'll need any tips along the way I'd be glad to help (I need about a day to answer)!

This is a ride I’ve done recently without the DB killers. The sound on the video doesn’t come though as well as in real life, but I can tell you it sound very good! Here is the link: kzread.info/dash/bejne/h2ervMWOm8nRhbA.html

Hello, Nice work :D How did you make the hole? What type of drill did you use to make the hole?

@gravelroadslovenia

I made the hole using a cone drill bit. Then I went around with a Dremel to smoothen the edges (normal sandpaper should work too).

Hello, nice vidéo thanks, did you try with only one dB ?

@gravelroadslovenia

Жыл бұрын

I haven't, however I'm not sure how that would affect the sound. Make it half as loud maybe? 😅

one question do you just have to make the two holes on the side or do you also have to remove the rivets.

@gravelroadslovenia

You can either remove the rivets and get the carbon off or drill the holes in the carbon. Both will get you to the bolts holding the baffles in. I personally did not manage to get the carbon cap off (it is possible but I don't know how). If you are planning to use the baffles every now and then, your only option is to drill the holes in the carbon. There are two screws securing the baffles, otherwise they might fall out without them.

Great video, thanks. By the way, would this add 1-2hp to the power of the T7 compared to the regular version?

@gravelroadslovenia

Жыл бұрын

The Akrapovic does add 2 hp over the stock exhaust, however upon taking the DB killers out, I believe you loose the 2 hp again due to the change in engine back pressure. If you were to remap the ECU however, you could see even bigger gains without the DB killers.

Hey, I have missed your comment, sorry. Send me your email and I''l send you all the dimensions and photos.

Thanks for the view inside the muffler. The pupose of the baffles is apparently to just reflect the pulses back for another pass across the holes that expose the sound absorbent material. In Slovenian, is the "krap" in Akrapovic pronounced as the English "crap"? Where did you learn your English? It's quite good American English.

@gravelroadslovenia

Seems to be so! What I have also recently learned is that the pressure pulses created by the baffles (back-pressure) aid performance. The top speed with the baffles is about 10km/h higher than without. Yes that is correct, "krap" as "crap" 😂... I attended an international school. 🙂

@gravelroad have you had any issues with the bike since you removed the db killers? I've read these engines run lean to meet emissions and removing the db killer can cause it to run too lean

I heard it is possible to remove the carbon however in my case it was not possible. Rivets cannot be purchased from Akrapovic directly, however I did find a company that was their supplier. The ones they use are watertight and of stainless steel. They are identical.

​@@v.gousis2241 the company is called Pnevmotex d.o.o, and the type of rivet you need are "blok zakovica rf 4.8 X 8 ZAPRTA". If they will refuse shipping it to you let me know and we will work something out. When drilling the holes you will need a high end drill bit. Installing the rivets also requires a professional tool since they are too strong to be clipped in with a classic hand tool. Since I went through the process I would strongly recommend avoiding what you are planning to do. Drill the holes in the carbon and get the rubber covers from Akrapovic, it still looks good.

u could use Self Adhesive Carbon Fiber Vinyl Wrap Tape to cover the holes 😉i like the stock look and sound. if i want louder exhaust ill get another one before i destroy (aka modify) the original Akra.
