gobasu Posted May 22, 2018 Share Posted May 22, 2018 I've recently changed exhaust to Leo Vince full exhaust: https://goo.gl/58xHkh + catalytic converter: "https://www.leovince.com/en-pl/product/6522k-catalytic-converter" Now I wonder if I should book ECU remapping for this all to work properly or I shouldn't really get worried about it? (bike seems to run just fine). Will it make a difference? Maybe there is someone who have this exhaust and went for dyno? I would like to know your opinions.

gobasu Posted May 23, 2018 Author Share Posted May 23, 2018 So I went to dyno this morning and the results on a stock map with baffle in and leovince catylitic converter in are here: I found it a little bit disappointing :> Does it looks like a stock figures? or should I go back to stock exhaust? Now I want to do remap but I am afraid I won't see any difference. Maybe I will just go back to stock exhaust? Dyno run: Link to comment Share on other sites More sharing options...

norcal616 Posted May 23, 2018 Share Posted May 23, 2018 the only dyno graph I have of the stock exhaust vs a tuned stock exhaust is this... ... dyno graphs dont show full story... you can have 1st class HP/TQ firgures but it rides like poo or you can have a tuned bike that makes a tad more power tham stock but rides butter smooth... my vote is re-map for leovince... 2012 wr250f - C-class 30+ age group 2015 fz-07- Hordpower Edition-80whp 2015 fj-09- Graves Exhaust w/Woolich tune by 2WDW @120whp Link to comment Share on other sites More sharing options...
gobasu Posted May 23, 2018 Author Share Posted May 23, 2018 Thanks a lot for a stock exhaust dyno chart! I believe it's very similar to what my leo spits out now - that was my aim to not kill it or loose power. I guess next step is to do remap and check how it will behave without cat. I somehow like idea of fresh air but do you think I loose a lot by keeping it? Link to comment Share on other sites More sharing options...
norcal616 Posted May 23, 2018 Share Posted May 23, 2018 You will gain better motor behavior with a tune... since you already got the "cat", you might as well use it or use it as a expensive ornament for your shelf in the garage or letter holder? 2012 wr250f - C-class 30+ age group 2015 fz-07- Hordpower Edition-80whp 2015 fj-09- Graves Exhaust w/Woolich tune by 2WDW @120whp Link to comment Share on other sites More sharing options...
