Removing Catalytic Converter Question

I've had 2 scramblers, first was standard and I fitted a sc projects exhaust with NO cat I would say the bike lost most of its bottom end but gained a tiny amount up top, i ended up fitting a booster plug which did help but didnt cure the issue, not good but sounded great. My second scrambler came with a termignoni fitted (with race ecu) and now at 5000 miles it absolutely flies, sounds great, goes great, has loads of bottom and definitely more top, has a proper forward powerband surge that makes it a really fun bike to ride. So I would say if you replace the std exhaust for a race can, to fully benefit you need an ecu upgrade.

Which is all still between the ears unless the differences are really significant. Seat of the pants dynos are notably uncalibrated.

Ever dynoed that second Scrambler?

Can't say I have but my ass tells me there's an improvement somewhere, I recon the noise also helps with the overall experience.
