kingofthenorth Posted August 3, 2018 Share Posted August 3, 2018 It’s more complicated than just drilling holes in the exhaust, but the result is very nice considering it’s free (if you can weld) Link to comment Share on other sites More sharing options...

DeepSix Posted April 25, 2019 Share Posted April 25, 2019 (edited) EDIT- Proceed with caution. After drilling my exhaust (Read below) the bike sounded much better and ran great on the couple of short test rides I did. HOWEVER, when I actually got it out for a real ride today, it felt like it was missing something. I turned off the TCS and it will no longer do a wheelie in 2nd gear A mode. This MOD appears to have killed the torque. It still rips through the revs like normal but has just lost a lot of grunt. I'm going to weld up the holes and see if I can confirm this is what's going on. JCG- Thanks for the idea. I didn't realize it until I'd posted a different thread tonight but your question is what got me started. I did as much research as I could online but most examples were FZ-09. I honestly didn't care if I made a mistake and the exhaust was destroyed, It's not worth anything anyway. So why not take a stab at this before spending $600-1200 on a new exhaust? I drilled seven 3/8" holes under the guard in the back of the muffler. Here are the results although it has a deeper, more throaty tone than my phone could capture. I'm thrilled with this ZERO $ mod and it took 20 minutes start to finish including test drives. Edited April 26, 2019 by DeepSix Link to comment Share on other sites More sharing options...
Guest Posted December 8, 2019 Share Posted December 8, 2019 I put a Delkovic on mine and I felt like it was flat after. I spoke with Dave from Vcyclenut and he confirmed that it probably was losing some grunt. I sent him ECU and he flashed it and the bike came back alive.
