Wise ass answers are okay by me as long as they're informative.

My build is using there clutch
I’ll try to report how it compares to stock

[Blazes Boylan]

Personally, I'm leaning towards the cam and high compression pistons and leaving it at that.  I'm strictly a street rider and both kits together come at under $700 if I install them myself.  I've got plenty of tools and even though I live in NYC I'm fortunate enough to have a warm place where I can work on the bike.  I figure that's a good project for next winter.  My last bike was a '76 Sportster XLCH and I never replaced anything more complicated than the gas tank but if I don't lose my nerve or get talked out of it by sage voices I'm gonna go for it.  All those Allen Milllyard videos are having an effect.  I don't see myself crafting custom parts with an angle grinder though.

Boylan, have you looked at the dyno results Revelry has posted going that route? They have separate dyno charts for stock; air flow, cam and piston; and air flow, cam, piston and Powertronic on their second tuner video. Without the Powertronic, torque wavers considerably.

I've been comparing a fuel tuned version against stock, staring, rev matching for power output and I don't think I can justify $3k for what amounts to 4 or 5 hp and 3 or 4 ft/lb gains in everything below 5,500 rpm. I love that torque carries higher further and that peak hp is a good +9 over stock, but a lot of that power and pull sits at rpm that equates to significantly illegal speeds.

I haven't decided anything for certain. Installing the cam and pistons yourself will save big money. I'm not sure I'm ready for that now, but like you, maybe next winter.

[Blazes Boylan]

Thanks, JL.  I'll look at the video again.

[Jared_Lee]

No problem. I actually took screenshots to make it easier on myself to compare. I'll attach them here.

In preparation for the other parts I installed my tec 2-1 tonight.  Sounds healthy

I’m running without the baffel

[greentrumpet]

I may be wrong but (mis)? remember tec bike saying on their vid that running without the baffle is not good for the engine. If that is the case I don't know why they'd make the baffle removable. I'm baffled. iirc they also said the booster plug was no use with these pipes. After giving it serious plugging before.

I’ve watched most of those videos more than once and this is news to me. It’s possible I missed something.  In which video did he say running without the baffle is bad for the bike? And what about the booster plug?

I can't tell you which episode but I do remember him making that statement. For me it took a bit of the shine off. It might have been an ad lib based on a extrapolation of a theory.

At 18 minutes he says no need for Power Commander etc, can't find him saying about the baffle so apologise if I'm mistaken.

[Gremlinsteve]

At the end of this build it will or should be getting tuned.   So I’m not so worried about it

From looking at that video, it seems to me that the "db killer" likely supports the back end of the perforated pipe inside the can. I suspect that the perforated pipe inside may crack from road bumps or vibration if the back end of it is not supported.

I have not seen the inside, but that was the impression I got from the video.

Regarding the full kit and performance, I get the impression it is for looks and sound, but not much for performance. Price is good for a full stainless kit.

That makes all the sense in the world to me. Good catch!
Without a connection at the rear end, that is a very long "lever" to worry and crack the front seam of the inner tube.
I haven't seen the DB baffle but strong chance it is an off the shelf unit made by another company. And that would make good sense to keep the price low.
