I recently purchased an eBay full exhaust system from headers to where the cat used to be. I have then attached my old slip on which is just a straight open pipe. After starting the bike I was blown away with how loud it is. For someone who loves loud cars and bikes I actually think this is just way too loud. The ground vibrates around the bike and literally everyone was turning the head when driving down town. It almost hurts my ears when riding along! What would be a solution to make it not so loud but still louder then stock. Should I also look at getting a piggy back ECU like a power commander. They are just so expensive and can’t really justify buying one. Although the bike does feel more sluggish and not as powerful now! Thanks I’m advance for your help.

The power commander is irrelevant. (It's not a noise-control device.) You need an actual, real, effective muffler.

I’m familiar with it not being a “noise control device” my concern and enquiry into a power commander was due to the bike feeling sluggish and loss of power.

in regards to sound if I where to get a muffler slip on it will make the bike sound better. Not so loud?

GoFaster's input is spot on. There are numerous slip-on reviews with 'before and after' dyno charts available for the different brands. Almost without fail, the noise reducing insert installed on most slip-ons yields better output results than without them.

Either fabricate a silencer or just buy another slipon that comes with a silencer. The latter would be the better option if you go the Chinese route as they are so cheap.

something like this? The slip on is just so expensive considering they are the same price as the full exhaust system I bought (just didn’t have the muffler).

I have tried a bunch of aftermarket Slipons, mufflers, full systems, the best I have found is the long muffler (470mm) not the shorter 390mm or 310mm that comes with most full systems. It is the quietest even with baffles removed, gives a nice full sound and the most power, by far here is the link to aliexpress 45.99US $ 10% OFF|Motorcycle ATV Exhaust Muffler Pipe 470mm Long Type DB Killer Slip on Exhaust Tip Universal For Yamaha TMAX530 500 CBR| | - AliExpress

The one you linked is designed to attach to the OEM cat so won't fit your full exhaust. You need a generic slip on with a 51mm connection. Personally I'd stick with the 370mm length (sorry R3Wheelchair) as this length is closest to that of the M4, Akrapovic, Arrow exhausts for the R3 that have a heck of a lot of R&D put into them.

Here's a link to the one I have (370mm-F). I only did a quick search so you might be able to find it a bit cheaper than that.

If you're wanting something asap, I did a quick search on Gumtree and found this which is essentially the same thing. N.B. The seller says it's carbon fiber but it's not (it's just carbon 'look').

To add on to this, the R3 also likes to have the quiet insert installed, gives it that little bit more. You can read Jesse's write up on his site

I ordered the exact same slip-on but from aliexpress. Got it for 95 AUD. Its in the post right now and is with Auspost. Should be on my bike around next week. When its installed I can send a video or give feedback. The difference is that I got the stock exhaust system, just replacing the muffler with the slip on. If you want the one I bought go to aliexpress and search for the "iSTUNT Store." scroll through and you should be able to find the one I bought. Again, I don't have the exhaust right now so I don't know if its even good.

I can't understand why people spend all this money for a good bike and then put junk on it. Decorative parts from Ali okay, I get it. Full exhaust systems, brake levers and anything concerning the way the bike runs or safety wise is a big no no.

If you read some of the previous comments you'd see that this slip-on doesn't meet his requirements as it's designed to attach to the OEM cat, not the mid-pipe of his full exhaust.

The majority of full exhaust systems from China that I've seen (and use) have no issues whatsoever. There are plenty of members on these forums who have had no issues or complaints either. The welds are machine welded so are better than what most humans could do.

In saying that, some slip-ons (not piping) that come from China skimp on the amount of insulation material on the inside and the casing of some of them can warp or fade so you need to do your research.

Personally, I refused to spend over a thousand dollars on a branded full exhaust that will only get me a couple of extra HP on a $7000 NZD bike. I've been more than happy with my decision. Even a guy who specialises in fabricating custom exhausts for motorcycles couldn't believe what I paid for mine when I asked him to fabricate a bracket for it.

My main consideration is the pipe transitions. They affect the exhaust gas velocity which affects scavenging and the AFR reading on the bike. that said, I am currently running an Indonesian made pipe which is used in their local track scene and they do have some local pedigree for half the cost of the brand name ones. As I understand they also do OEM work for Scorpion exhausts.
