R6 Exhausts & Mapping

[Carl-52]

i think it will be fun when i jump on Stu23's bike XD 75kg and lots of power....

Haven't read the whole thread but I just cut the cat converter off my R6 which had a stubby GYTR(?) slipon on. We put a midpipe on and one of Marshy's slipons and it works great! Saved a good 5-6kg and it runs noticeably better, really howls after 10,000 now. Sorry can't remember the brand of slipon.

I'm sure there are better more expensive solutions but bang for buck wise I reckon this solution would be hard to beat. I'm really glad I didn't spent nearly $2K on a full Ti Akra system like I was thinking of doing, just don't think the gains warrant the spend IMO. Although they do look trick!

FYI.

Mine makes 111HP now. 2010 R6. Mine since new. Stock engine, full Akra system with Stainless headers. Just kicked over 21,800 km's. Mapped in August last year.
I had it mapped with the stock system on it in February 2011 when it had 6,500km's on it and it was...... 111HP then too, up from 106HP

However, the increase in mid range was instantly noticeable. Also noticeable was how quickly it gets up into the rev's now.
Once i had that system fitted i was suddenly starting to ride in the rev range that the bike wants. ie- 9,000 > 14,000rpm.

It was dyno-ed by Trev both times.
There may have been more factors at play than the exhaust upgrade but it makes me smile.

Around the same time i lost 6Kgs off the bike with the exhaust i put on around the same myself so i never noticed the difference in top end speed like i did the first time i hit the main straight after i'd stripped the road kit off and put race fairings on.
The attached graph shows the 2011 mapping in Green, the 2013 pre map in Blue and the 2013 postmap in Red.

goodnight.

It used to make 112 with a jardine slip on and a backyard mid pipe. Then put on the big full system and the stacks and got another 2 peak, but the impressive part is the hp stays flatter after 14 grand where as it used to plummet 8hp between 14-15.5.

That's a good nice power curve too
