TE511: US stock vs Akrapovic - how much lighter is the Akrapovic?

Anyone know?

Trying to figure out if I need to bite the bullet. I'm adding weight (tank, rear rack, etc) and it'd be nice if I could remove weight at the same time (already got a Shorei battery...)

3kg looking the the attached video

Thank you!

Won an ebay auction, under $400 for the euro akrapovic, not bad

klinquist, look for a titanium exhaust TC449. It is much lighter and better, than stock screen-type stainless Akrapovic TE449. Header need to replace too. I use them.

Too much $$ and I need a screen/spark arrestor here.

TC449 system comes with a spark arrestor, but it is expensive.

Also, that is the aftermarket Akrapovic. The stock euro / aussie akra can is heavier than that. I haven't weighed mine but it's probably somewhere between the two. However, it is quieter as well. I think mine is a nice compromise between being quiet enough as to not draw attention and still providing some power/weight benefits over the laconi (sp?) stock US can w/catalytic.

The exhaust Normann linked to is actually not aftermarket, it comes stock on the TC449. The aftermarket is the Evo One with resonator and carbon tip. The Euro/Aus Acropovic was oem on the US TXC models (map 3 works great with this exhaust). All three of these Akro systems are very quiet compared to the F brand 4.1's which I can only describe as rolling thunder. I've tested all of these exhausts. I took a 4-5hp hit from switching away from the 4.1, but the Acropovic is so much quieter.

I'm happy with my TC449 Euro/Aus Acropovic on my SMR. With the TC airbox it is a borderline pass at it's annual vehicle test in the UK.

Tinken, how come you switched from the 4.1?
I thought they were the biz...

Based on what he said I'm guessing it was just too loud. Many riding areas in the US has noise restrictions.

Too loud/business ethics of F brand corporation has me a bit annoyed.

This is the one I got on ebay (on its way to me now)



Sounds like I made a good choice. I wanted lighter/smaller than stock but still quiet. I often ride in national forests around campgrounds and I want to 'leave no trace' including noise.

I like my Aus supplied Akra slip-on. I know it's not the last word in Dyno figures but it seems to make good mid-range torque, isn't too loud & is well made.

I have the fullrace ti/carbon akra evo system on my SMR449,
It is very light! The header weighs virtually nothing. The can is prob less than half the weight of the large laconi stock can.
Could be made lighter still if it was cut shorter.
I run it with no spark arrester and have no issues with Dba limits on the track, on the street it does get some attention though.

For what it's worth - I got the ebay item and put it on the scale. Exactly 3lbs lighter than stock.

There's another 2lbs less to be had in a lithium battery

Got a Shorai on there too
