Street Twin Bafflectomy

[Edawg]

Anyone have experience with a bafflectomy for the street twin? Triumphrat is a pain to research on because the boards are a bit jumbled (part of the reason I like this board more).

Was curious about back pressure (still have the OEM cat installed), fuel/air, sound and whatnot.

I'm bone stock now and I Love the current sound, just want a bit more.

Ultimately want to go slipons/fatness, but don t want to spend the dough until I get back from deployment...

Thoughts?

Anything after the cat won't matter much for performance (or back pressure concerns). Sound will change but not as if you delete cat. Then you need to address a/f ratios.

RHB- much thanks... louder=safer!

So putting a straight pipe on will require an ECU/power commander change....

Hmm. So now I'm gonna need like 1500 to do my cat/exhaust? Higher octane(91/93) wouldn't do it? I'm running midgrade now, which I read is what the manual says...
Not trying to challenge, here, just asking.

No ECU change, but perhaps A/F management.

octane has little to do with anything you are talking about. If you could flash your ECU(you can't on a WCT) then timing changes might require higher octane, but the engine is so under tuned, it won't be necessary or of any advantage to you.
If you change your exhaust AND install a decat it is recommended but not required that you use at least a booster plug to richen up the open circuit map. beyond that you can buy a power commander but then you need to get the bike dyno tuned to make it work properly. But it is not absolutely necessary to add a fueling device. as the bike runs rich anyway, just safety precaution and fine tuning. Pay your money take your chances. I run a Booster plug, and it still runs quite rich but I don't have a CAT delete yet just slip ons and air intake mods.

RHB, again thanks for they detailed reply. I had assumed that the problem would be I was running leaner. Got it and thanks
