Default What will happen if i do this?

Hi there,
My first post here. I am posting from Singapore, a hot place like Arizona, except for the 95% humidity here.

In singapore, we have similar EPA rules and noise polution rules like in some of thestates in USof A.

I havea 2005 FI Road King Classic, with the following done on my bike.
-SE slip on pipes
-SE 203 cam
-SE stage 1 air cleaner kit, with K&N air filter
-ECM calibration for the above.(i think, as it was done by previous owner)

My question is simple...
What will happen if i slip out the SE pipes, and put back the stock catalytic exhaust pipe?
-Will it cause any ill-effect to the bike? (was told by prev owner nothing will happen)
-Will the bike run fine with Stage 1 calibration?

Why do i have to do this?
-Because of the EPA rules here that 3 yr old & up bike will need to be inspected for noise level annually in order to enjoy theriding priviledge on theroad.(the SE pipes will fail the inspection)

Thanks everyone here, Ride safely!

Welcome!

Someone elsewill answer this better than me.

When changing slip ons you change backpressure. With your other mods I would stay with the ECM calibration.
I don't think the slip on change will make that big of difference from SE to Stock.
I'll be curious to see if you notice any performance difference?

Hey thanks for the fast response and attention.

I am not so concern with the performance difference, because i only want to put back to stock catalytic pipes for a few days of riding & bike noise inspection.

I love my current SE setup, although it is not the best one.

So, as soon as i pass the inpection, i will slip back the SE pipes. Just want to check with all of you here whether it is disastrous to do so.....ha thanks for the warm welcome...

If anything it might make the bike run a little richer. Do you have to get the bike inspected for noise only or will they check the exhaust gasses as well?

Yes, they will check for the emission. The last time i went for the inspection, i saw them slipping a pipe like sniffer into the pipes(it was a japanese bike back then)..So i guess it is a "yes"
Does that mean likely a "fail" due to a richer AFR?

That would be my concern. I don't know how tight the regulations are there but you could try swapping the pipes and have it tested. Here if the car/bike fails you still have to pay them but they will retest after you make changes. You may need to find someone local that knows bikes and the test they go thru and see if they think the bike will pass. Good Luck!

You'd be better off with an auto tuner such as a ThunderMax module.That would allow you to go back and forth from slip ons andan air cleaner, go for testing and then switch the stage 1 air cleaner and slip ons back for performance. It's a simple program download from your own laptop to go back and forth. By switching the pipes and the air cleaner, you're going back to stock intake and exhaust which should pass, and the Thundermax tuner will allow you to quickly reprogram yourself, if it's even needed to change from stock to stage 1. I say that because it can tune itself for small adjustments like this would be. Therefore, you'll likely not even need to download a new map, just plug and play.

You can order one from Bart (Shooter64) here on the forum. Look him up as he suppliesmany of the forum members with parts that are priced right. He ships internationally too.

It's the same over here. If the test fails, we got to get the bike setup changed and retest again within a given time frame. If it fails again, i'm not sure what will happen. And this is exactly what i want to avoid.

Thanks, i will definitely ask someone closer to me around here in Singapore about the test procedures.

Besides, if i want to have a better control of the situation, i guess i got to either:
1) Get a PCIII and tune the AFR ( can PCIII lean AFR?)
2) Get a SERT and tune the AFR (i know this surely will work)
3) Send the bike annual back the dealership and pay USD200x2 religiously every year to have it map/re-mapped.. (Ouch!)

What other options do i have?

That's why I was thinking you need to find someone local that knows if the stage 1 download will pass emission testing there. You never know it might pass after swaping the mufflers out just as it sets.
