Hi all
I just de-baffled my stock pipe, and replaced the TORs, nice sound deep and punchy.
Q: the TORs used to pop and splatter, and that’s ok. But the de-baffled ones pop and bang .
Should i be worried?

depends on the year, but adjusting the pilot mixture screws on carbs will help that.
If it's FI, then a remap is in order.
A word to the wise is not necessary. It is the stupid ones who need the advice.

What he said EFI model = remapping essential.
Also on EFI adjusting the regulator will increase/decrease the snap crackle and pop.

be sure you have no exhaust leaks, that will cause the exhaust to bang more due to the leak. Also check the intake side for leaks. Remapped for TORs will probably still leave you lean for straight pipes.

Excuse me for being so ignorant, but how do you do the remapping? I havent a clue when it comes to the engine, i'm a rider, and a pretty one at that!

You plug the bike into a computer and change the fuel map to put more fuel in where needed so you don't run lean. The dealer already has a map to download into the bike for TORs not sure what else is available from people like Tune Boy or one of our members who was working with maps. I can't remember who it was off the top of my head anymore.

On the EFI bike the problem is going to be with the O2 sensors, they are located on the exhaust headers.
A free flowing pipe will have the senors sending feedback to the ecu. The ecu then try's to correct mixtures (within the limits that are mapped in to it). Which means, (as stated) remapping.
The solution I used was TUNEBOY programme which bypassed the O2 sensors.

Now you tell me... you're not that far away... 
Tbh, if you are not technically minded the dealer (or any reputable garage - though these are not always the same) will be your best place to go for a re-map.

06 America - missing, presumed in bits. With it's TBS wheel... 
09 America - It's very blue....

If it was remapped for the TORs, then that's the only map alternative you'll get from the dealer. Check for leaks (as mentioned above) before you do anything else. The ECU is fairly adaptive and can accommodate increased intake and/or exhaut flow within reason.
Significantly freer flowing pipes than TORs will need further custom mapping - only available with Tuneboy or PCIII. Most have chosen the Tuneboy route because of what Davo says about the O2 sensors (above) and because of other advantages. You might want to also increase the air intake to balance your increased exhaust flow. Whether you choose Tuneboy or PCIII it's helpful to perfect your tuning on a dyno (choose an operator who understand Tuneboy or PCIII).
Removing the AI system will also help reduce popping.
Do a search on EFI - there's a fair bit already discussed on this forum.
Cheers, Richard

I just re-read this opening post to this thread and wondered...
What is the difference between "pop and splatter" vs. "pop and bang?" What I know is the TOS on a carb model do not necessarily involve the use of bigger jets. In other words, the TOS are a rather mild version of the 'open pipe' concept, which equated to little to no concern over fuel mixture. Remapping for a (slightly) richer fuel/air mixture would I imagine be ultimate, but not necessarily necessary.

If you are able to find somebody with a dyno and who does bikes and also has experience with tuneboy then you will be on the right track. On my 09 America I found that when I added staintune pipes and a K&N air filter and also removed the AI if ran so much better. Nealy all the popping gone from the exhaust. The snatchiness and the sometime hesitation off the line very much improved.I did find that it was still to lean so I bought a Tuneboy and had it dyno tuned. O2 sensors are now disabled and now that it is getting the fuel that it needs she runs like a dream. If you rode my bike before and after the changes you would not believe that they were the same bike. That is what worked for me, however all bikes are different.
Hope you get her running smooth they are a beautiful machine and run oh so sweet.
Cheers,
John

+1 ... that was my experience also. She runs so smooth & sweetly ferocious now - perfectly mapped and tuned.

On the EFI models you need to disable or remove the AI in order to eliminate the pops and bangs. When I installed my exhaust it was really popping a lot on decel especially when down shifting. I put a 16mm marble in each or the AI tubes and the popping stopped. Since then I have removed the AI entirely. It is a fairly easy mod and well worth doing.
09 Speedmaster EFI - Custom Stainless exhaust - Progressive 412HD rears - Corbin Solo - Polaris Bellmouth - AI removed - 4" Rise "T" drag bars - Custom A/F map - so much more to do!
