    I know there are a number of posts already on here about slip-ons and cat deleted, but it seems like a lot of information is scattered through out and not aggregated.  Wondering if anyone has any good sound clips/videos of the various different exhausts and personal recommendation.  I have heard that the competition werkes slip-on is loud but have not been able to hear it up close.  Any help appreciated.  Thanks

    hello,

    Here is my svartpilen with no cat, the slip on is an akra with db killer and it s very loud.

    I can t remove the db killer it s too much for me lol

    The sound with the husqvarna exhaust is very good with decat. But i bought the bike with the akra.

    I agree with above. I have the cat delete from Competition werkes …the Akra slip on did little to nothing over stock until I ran the cat delete. It’s loud but not annoyingly loud …also feels like HP gained a bit too, bike feels much more complete and at home with the cat delete

    Looking at getting this, its nearly half the price of the akro slip on for the svart 401. Anyone found anything better / cheaper? I quite like this look over the puny akro. Thanks.

    I ended up getting the Akro, and got it through my dealer for a fraction of the price it lists for online.  I believe I paid about $300.

     

    In terms of sounds, it didnt make much a difference, but I do notice the sound a bit louder and slightly more aggressive in the 5-8k RPM range.  Overall not a huge difference though.  Considering doing the cat delete as well.

    I did the same mods, Akra (with db killer) + Cat Delete. But I feel like I’ve lost some torque in the process over stock. Top end feels more agressive (sound could be a huge factor here)

    I’m OK with trading some torque over pure fun.

    How’s your experience?

    Duke 390 “slip on” with a diy rear peg delete. It will fit with the supplied hanger and factory exhaust support as well.

    The pic below is an Aliexpress knock off. I was super impressed with the quality. It was less than $100. I did modify it a bit from what was delivered. I shortened the whole set up and welded on the can.

    I’m looking at getting the Remus slip-on. Anyone here have one?

    Yes, I have one and can recommend it. I fitted just the Remus slip-on and kept the rest (cat and pre-silencer box) standard.

    Sound is noticeable but not annoyingly louder with a slight popping when shifting down.

    Best price I could find in Europe was at Mecadata: https://www.mecadata.com/remus-husqvarna-vitpilen-401-2018/451400301-silencieux-pot-echappement-remus-sport-flow–husqvarna-vitpilen-401-2018.html

    Good to hear. I think I read somewhere that the db-killer can be removed with just a screw, is this correct? Would be nice to give it a go, and put back in if it’s too obnoxious.
