Maybe NOT... air induction is more of a change then exhaust is...

I was not planning on any airbox mods because I am not really trying to gain HP. I just want a better sounding (louder but not obnoxious) exhaust sound. If I also pick up a few HP and drop a few pounds that is just icing on the cake for me.
Can anybody say for sure if my EFI system will compensate properly for an aftermarket dual outlet exhaust system? I do not want to have any driveability issues or have to spend money on anything other than the exhaust system.

Allen should know if you will need a fuel programer with an exhaust change. Try sending him a PM or I'm sure if he see's this he will let you know.

I will tell you my story and you can take it from there___ in the spring of 06 I snow checked an 07 RTX er with Pat Hauck (quite the salesman) I told him I wanted a 1" track with 144 studs, a good clutch set up, his pipe, a fuel excellerator, K & N's, 3 degree advanced timing, he than talked me into his speed sheave and an autostart.
In october of 06 I drove from North East North Dakota to Rice Lake Wisconsin (15 hours round trip, booken it) I waited for snow and began to ride. In the mean time I found this site and found out I should have just left well enough alone, Why?
My sled was loud way to friggen loud (up Front K & N's) the pipe sounded awsome but over all the sled was way off of what I expected, every once in a while It would decide not to run right, it would spit and sputter and run like crap,.
When the season ended I had 575 miles on it and was not a Happy Camper. Tried to talk with Pat now and then and all he could say was "bring it back down and I will ride it".
<<fast forward>>
Last summer I made a phone call to Allan Ulmer and we made arrangements to get my sled to South Dakota, I sent with Him My goals and what I wanted to achieve and left the rest up to him.
I wanted:
-top end
-my airbox back
-a fuel controller that worked
-kept my pipe
-smoked medium windshield
-and all suspension and every nut and bolt checked over
Now let me say, He is the best at what he does and he is a top notch buisiness man on top of everything else THE BEST hands down.
My 07 RTX is like in his words "Bang on" it has:
-stage three clutching (23 top gear and 70 link chain)
-fuel controller
-his air box mod ( way quieter)
-hauck pipe (sounds unreal)
and this sled just flat out hauls A$$ on a hard groomed trail I have been up against everything from a very fast modded F7 (brothers) a new 800 R Skidoo and held my own real well.
now this all cost me time and money and the lesson has been well learned but I am 42 years old and have been riding since 1974 and I can not even ride another sled and have fun, I dont even care if I am the fastest sled I just know I love the way mine is set up it is once again Bang on.
Oh and by the way if you own a 4 stroke sled you need to puchase a ProHonda Optimate battery charger and just leave it hooked up when not riding it, you will never foul a plug or have a starting issue.
Thanks again to this web site and The Ulmers, I am a Happy Camper!!!!

okay.....haha i just went through this a few weeks ago and allen ulmer helped me out.......with....you will only know you are leaning it out if you have a bog somewhere.......for me when i put on my sno stuff exhaust only....no bog......however i put on ram air a few weeks later and noticed a bog.......allen told me how to up the co's on the pod and i did just that which turns up the fuel to each cylinder and will help get rid of a low end bog as it did for me.....however will not help with mid to top.......but i have no bog mid to top so im good there. HOwever i still would suggest getting a fuel programmer anyway to be safe.....i think im going to this summer so i can adjust my fuel curve as well
