Recently bought a 2020 yfz450r and looking to buy a full exhaust for it as well as ECU and intake. I would like something that puts out great power but doesn't kill my ears when I ride and doesn't piss my neighbors off that much. I go to the track every few weekends as well. I am probably going with the Vortex ECU so what would be the best exhaust and intake for me?

That is the combo I was leaning towards. Have you heard anything about FMF or Yoshi?

From experience...Fmf is pretty good. Between fmf and hmf id rather go hmf instead. Hard and very slight distinction between the two besides the sound and look though.

Yoshi I cant help you because Its never been an option for me nor have I rode a quad with one, just seen it. Im just not a fan of the look at all or sound as much.

It was DASA all the way across the board and I could not be happier I picked it. FOR ME, its the best looking, and sounding on the market for sure. And the performance on it is ridiculous. Love it.
Also to answer the noise levels... make sure to get the 99db if you do decide to go with DASA because the classic is SOOOO damn loud.

The 99 DB would decrease the power wouldn’t it?

If your really concerned about the noise.
Go with the classic and buy a quite core. Itlldrop the noise levels to 96db AND when you dont want it anymore you can take it out. The 99db can is what it is and you cant insert a quite core.

As far as power goes, (im not one of those people on here whos biased or thinks i know it all like some) i truly do not know. I would ASSUME any quite core or can would decrease power but enough to notice? Probably not. But again just my opinion make someone else can agree with what I assumed or help out with a little more info on that. I like loud pipes and the sounds of it even with my banshee so I wouldn't know for sure lol

Yoshimura quality right there nice and short and has a decent bark. If you want the yoshimura to BARK HERE I COME SOUND TAKE OUT SPARK ARRESTOR.

FMF PIPES LOOK GOOD TOO BUT TOO god damnn long. Same with HMF too long of a muffler too.

If you're concerned about noise I would get a Yoshi. But the Sparks with quiet core is pretty badass too. Talk to Ken at KB Motorsports and he can hook you up with a package deal.

Yeah dude. Theres a gas station half a mile away from my house. (0.4 miles exactly actually). You can legitimately here me coming from there from my house lol
Anyone who says it ain't loud is lying. For a fact thats one of if not the loudest 4 stroke pipe on the market. But I love it in everyway! Hahaha
But to each his own for anyone, were all YFZ folks! Safe riding!!

We were all just showing and talking about exhaust pipes and the db levels....

No need to flex on us that hard. Your FMF pipe and info would have been good enough. Haha

Lol I just hope the mods list helps!
Btw, I love my FMF pipe. I know it doesn’t make more power than DASA, but it makes a difference and sounds good without being too loud.

FMF on a stock engine: smooth, good curve, best sounding pipe I’ve ever heard.

Yoshi on a stock engine: good midrange, super quality fit. Best fitting pipe I’ve ever seen.

Yoshi on a ported and cammed engine: solid midrange, hard bark, pretty distinct.

RP Race on a built engine: loud, light, sexy.

Personally, I prefer either of them. Rossier is everywhere on Facebook but they make good power. Same with Dasa.
