I've talked to a lot of people that tell me to get air intake as well as retune the bike if i want to install Vance and Hines Big Radius 2 into 2.

Today at the dealership the service technician told me I do not need to get a tuner if i just want to install the exhaust.

So my question is I am tight for cash right now because of other commitments but I would like to get the exhaust done for my wife's bike.

Do i need to get a tuner as well as a new air intake if I just want to install Vance and Hines Big Radius 2 into 2 exhaust?

 

U don't have to re tune for just exhaust, or just for a new intake but it would definitely help.. Get a set of xieds to add more fuel and skip the tune.. I have a set for sale lol

 

Thank you for fast reply:

I am aiming to get Vance and Hines FuelPak FP3 and their Vo2 naked air intake in the future but for now I can only afford the Vance and Hines Big Radius 2 into 2 for her.

 

Just for thought for down the road, do a bit of research on the DK Custom Thunder Torque Inserts, I used them when I installed the V&H Big Radius 2-2 on a NightTrain and they really made a difference in bringing back the bottom and mid range performance the pipes had softened... they sounded better too, the bright V&H rasp was replaced with a deeper tone

 

Ok thanks mate I will do some research on that thank you for the tips.

 

You might find that the biggest disadvantage to only installing an exhaust system is the decel pop. I installed pythons staggered and it was horrific. Threw a k&n in the stock housing and installed an fp3 and its near perfect.

 

Torque inserts didn't work for my hooker troublemakers which are basically the same as the radius. I dnt remember what brand they are but they are all close to the same and don't do much. I have a set of those too I'd sell lol.. As with everything results vary from person to person and bike to bike I'd say skip the torque crap because u won't notice it because u are going from stock to a little better than stock so ur but dyno will only register a gain.. Ur right hand will twist more as well.. I'd also say get some xieds cheap and will fix any decel pop for most people

 

I read online somewhere other people had decel pop problem but it went away after using FP3 so i think i will get the FP3 when i have money

 

Just curious. Was the install easy? I installed some other baffles a while back but they didn't fit perfectly... Which one did you get exactly?

 

Which torque did you get? Easy installation? Also would it be the same on a sportster?
