Suzuki GSX8S / GSX8R lextek full exhaust testing and tuning results

[@nickrider5220]

The gsx8 engine gives huge gains, in an age when big across the board gains are rare - lovely 👍🏻

[@freddykwanten2700]

great gains for the money. nice work again

[@vcyclenut]

Appreciate it!

[@pakattak420]

Which Yoshimura do you have coming? I got my pre order at2 speed series with cat,installed last week, sounds great, just waiting to do the airbox and get your flash once I see what ya get

[@vcyclenut]

Unfortunately I had to move on to the next project and I don’t have the gsx8 any more. So I won’t get to do direct testing on it Based off of its configuration it going to be very similar to the akrapovic

🤘😎

[@thefunnydude312]

whats the loudest exhaust youve tested so far on this bike?

[@vcyclenut]

Probably the Toce

[@marcobrown5270]

Just recently purchased this exhaust with no tune and my gsx8r was overheating. Would your ecu flash fix this? I saw online that the bike could run lean with full exhaust no tune causing overheating?

[@vcyclenut]

I’m surprised that you had overheating issues from just changing the exhaust My flash will fix the lean air fuel ratio and turn the fans on earlier As long as your overheating issues are tune related the flash will fix it

[@marcobrown5270]

Cool I’m not sure about the overheating I changed it and drove it down the road and temp was blinking 248 degrees F. Could it be mounting issue?

[@vcyclenut]

@@marcobrown5270 did you drain the radiator to install the exhaust?

[@marcobrown5270]

Yes

[@vcyclenut]

@@marcobrown5270 when you empty jt you have to fill it more than once The process is to Let it get up to temperature so the thermostat opens Let it cool and refill it Your radiator is low. Top it off

[@poormansportfolio]

Out of all the exhaust for the GSX8r, which is the loudest & which is the best ? Akra, m4, toce, arrow etc etc?

[@vcyclenut]

toce = loudest akrapovic= best performance

[@DavidTysdal]

How much is it? Black widow is a good one also (cheapo).

@vcyclenut which MIVV system is on the way? I plan on getting the X-M5 since I want to retain the low mount look.

[@vcyclenut]

the x-m5, :)

[@SacrificiaLamb.The.Gixxerator]

@@vcyclenut oh I can't wait! Looking forward to that video, Please measure the sound level when you get the chance. Thanks

[@vcyclenut]

@@SacrificiaLamb.The.Gixxerator will do. I have sound readings in all my tests now

[@PatPatRoule]

Je viens de monter le miens, sp11c, malheureusement, mon sabot moteur ne se monte plus, les collecteurs n'ont pas la même courbure que ceux d'origine, et même avec la chicane, la moto fait trop de bruit

[@PatPatRoule]

Bonjour, il faut démonter le radiateur pour monter cet échappement ?

[@vcyclenut]

It makes it way easier but it’s not 100% necessary

[@PatPatRoule]

@@vcyclenut thanks !

[@aziivo5012]

which lextek system is this exactly?

[@vcyclenut]

Xp9c

[@aziivo5012]

@@vcyclenut Nice, thanks for replying. 👍I’m looking to get a system for the GSX 8R & this sounded real good 😊

[@whatspeedlimits]

Back to STD instead of industry standard SAE, and no A/F curves shown? Focus more on data and less on selling stuff. The stuff will sell itself if the data is good.

[@vcyclenut]

All Of the runs are in the same correction factor. The percentage of gains would be identical if i posted them in SAE My dyno reads low so i use STD Im not giving out the air fuel that i spent time figuring out what makes best power Sorry Sorry you dont find them informative.

[@whatspeedlimits]

@@vcyclenut On an normally aspirated engine- a wide range still makes the same power- there is no secret to it. But showing the before and after A/F most definitely shows how well the bike likes the mods, as well as your skill.

[@EscoVBWRX]

@@vcyclenut with the GSX 8R tune, do we get popping sounds on the exhaust?

[@vcyclenut]

@@EscoVBWRX if you want it. Yes If you don’t than no. It won’t
