2017 S1000R Akra gp slip on vs SC Project CR-T
« on: January 06, 2019, 12:55:17 PM »
Hi guys!

So I'm deciding between the Akra GP and SC Project CR-T titanium cans.

My question is which can is louder. I would assume SC would be louder. However, on their website the SC is euro 4 compliant and the dB levels are below the homologation limit, while on Akra website the GP can is a few dB louder and not street legal.

What are your experiences? Which can is louder?

And are these cans a lot louder than stock exhaust? As I've read conflicting reports. Some say it's not at all louder due to the cat and some say it's much louder.

Thanks!

Without replacing the stock headers or hacking off the cat, you're unlikely to get much more noise.  I've got no personal experience but that's what I've read all over this forum as well as in youtube videos.

You can change the "tone" of the sound, but you're unlikely to get a whole lot more volume due to how restrictive the OEM cat is.

Thanks for your reply!

I'm really confused now. I've been reading a lot of YouTube comments as well and I've messaged the people who own sc project and they say it's about 40-50% louder. And some say it's not louder...

Sound is a funny thing...  so changing the tone can often "sound" (feel?) louder, but I bet if they measured it with a DB meter, it wouldn't be anywhere near "40-50%".

Check out this video,


It does seem that the sc project is louder at further distance. Or is it just me🤣

  Agreed. I run the SC Project S1 (cat in place) a  very slight increase in volume and a nice bark under load. It was more an aesthetic thing for me. I found the OEM akra can on my 2018 too bulky.  A buddy runs Akra headers with the CR-T. Painfully loud as far as I'm concerned but hey, whatever floats your boat! I had a 'near deaf' experience riding a Harley Low rider S 114 CI with aftermarket pipes for the last 3 years. Decided I wanted real performance over 'attitude via decibels'. That said, if its noise you're after, headers is the way to go.

@S1000R1337 why not take your OEM can off completely and fire her up? I anticipate a small increase in volume, but nothing major. Adding a can is unlikely to make it any 'louder' than this, but may change the acoustics.

Hi - I've fitted the Akra Sport/ Race end can and it's much louder than stock on a 2018 bike - fuelling is spot on though - I'd say it was about as loud (if not a little louder) than the Akra end can I had on a 2016 bike.  Akra build quality and fitting is good (the end can has a bracket that fits to the exhaust hanging bracket - so it is retained and fixed well).

It's not marked street legal though - it has a deep tone and when the exhaust valve (open no doubt) is doing its work you can tell the difference.

Don't seem to many options for the post-17 bike. But to answer your question, yes, louder than stock and pretty much as loud as I'd like to go.
