So you are saying ECU flash before cat delete / exhaust?
Yes...do the ECU flash first.

That sounds strange. So are you saying that if you do the ECU remap, the computer will pick up the exhaust changes and make the appropriate changes? I actually thought you would need to give your bike specs before getting the ECU tune. Inquiring minds want to know.Okay....strong bit of advice ...before you do anything pertaining to your exhaust, do your map first...then look into the exhaust.
As I mentioned in my previous post I have the Monster stage 2 ECU flash and cat delete pipe without baffle on my Spyder and I am very very satisfied with the performance
When I tried the same setup but WITH the baffle I didn't like it because it felt restricted/ suffocated, especially when giving full throttle at any rpm's.
Today I decided I had to try the Monster stage 2 in combination with cat and stock muffler (= original stock factory setup) and I was truly surprised when I took the Spyder for a spin and realized it had just about the same performance but without the annoying and very loud exhaust note I had with the cat delete! ��
It really is a lot more enjoying to drive when not disturbing the neighbors or having to wear ear protection anymore. Especially since the performance is still very good'
Interested in how yours performs with the stock cat back on. I have a Daytona also with just the Akrapovic Sinister pipe. Am I running lean with no tune?No bark off the line but it picks up fast. I was expecting more off the line snap. Are you saying the stage 2 didnt help or could it be the baffles you're running? I'm considering the stage 2 and RLS cat delete.
I just got mine back from upgrading from Stage 1 to Stage 2 and I emphasize Upgrade!
Though I was somewhat happy with the Stage 1, I did find that my Spyder (2014 RT-Ltd) ran rough & jerky on take off when it was cold.
I couldn't wipe the smile off my face after taking it for a rip after installing the ECU with the Stage 2 flash.
The Spyder runs sooo smooth and the throttle response just couldn't be better!!!
Some have mentioned that the addition of the 2 air holes added to the airbox lid was noisy, to be honest I never noticed any increase in volume. The test ride was with stock cat & muffle. (Cat Delete pipe is on the work bench ready to install) :yes:
3/4" or 1"hole saw works great
Interesting idea, but why would you convert a reasonably properly designed and flowed cold air intake, into a reduced ram air effect hot air intake.
Years ago, I disassembled the air duct and gave it a look, expecting true restrictions for engine intake air. Yes, the entire duct could be removed and an external duct routed outside the bodywork to shorten the length and assure cold air was captured. This though requires good placement of the air duct inlet away from turbulent air created by the bodywork.
On the 14 / 19 RT series the oem duct gathers incoming air at the front of the Spyder, in the upper edge of the left radiator duct. The outside inlet appears small and restrictive, but upon inspecting, there is an additional cold air inlet that supplements to obvious inlet.
The 2014 to 2019 RT series Spyder utilizes a quite large still airbox, adjacent to the throttle body. This is a good design. It allows incoming turbulent airflow, to slow slightly, but more importantly reduce turbulence and allow a straight airflow into the throttle body.
There is a large duct that crosses over to the air filter airbox. By design, the airfilter initiates straightening the airflow based on the cylindrical shape.
Most engine builders and tuners know and understand that air density will alter performance. Cold air is more dense per volume and produces better power. Adding a warm or heated air bypass as shown will make noise and sound powerful, but likely, and I may be wrong, will reduce power based on heated air.
Going further, if that new set of holes could utilize the flush honeycomb style air vent below the mirror, possibly it could keep a cooler air charge near the holes. For me, when my hands are cold, often I place them over the honeycomb vents at lights to warm them up. Based on that, it is apparent the air around the filter box is heated.
Years ago, while researching the oem air duct, I considered removing all of the intake duct, except the still airbox. Plan was to install a K&N filter onto the still airbox spigot. For various reasons, including heated air concerns, I did not make that mod.
This isn't my idea. This is where Monster/Wicked drill the holes for their stage 2 ECU flash. You'll have to ask them..

Thank you, thank you, thank you PMK …… this is similar to what I have posted on other similar threads ….. However on the air turbulence thing, on the Spyder it occurs BEFORE the AIR filter element which imho calms the air significantly ….. I have pics in one of my Albums ( see Shock re-locators on RT 13+ ) of what my Air Intake looks like on my 2014 RT...… Because I wanted to be able to re-move my Frunk easily ( and often ) I built my new intake with a ( sort of ) SLIP Joint..... I can re-move my Frunk and then replace it in about 15 minutes. … My intake air comes from Outside the Spyder and is at Ambient temp.... good luck all …… Mikehyea:
