Would I need a fuel pack or any tuning if I went for the Vance & Hines Twin Slash 3 Inch Slip-Ons?

Your help is appreciated.

 

Just put the 3" slip-ons onto my 2014 Iron 883 and didn't need a fuel pak or tuning. Pretty simple and straightforward install.

 

Thanks

And you get no backfiring?

 

No backfiring.

Just be careful when installing the muffler to the mounting bar, it requires you use the existing hardware. I had a bolt sheer off and needed to take the slip-on to my local dealership to remove. They ended up having to cut it out with a welder and weld in a new nut.

I was not torquing on it excessively, it just sheered.

 

Not unless you also got a stage. 1 AC then you'll be fine. Change the AC too and you'll need to get a tuner.

 

Pipes only = not necessary. Just make sure you get a good seal between the pipe/header joint. I recommend using High-Temp Silicone (i.e. liquid copper) on the "inner" surface of your pipe when you slip it into place. Then torque to spec, ride 50-miles and re-check torque. Should be good...

 

Thanks for your replies. Appreciated!

 

No backfiring? I backfire a lot on my 48... No other engine mods done to the bike, just the pipes.

 

Are you running the quiet baffles?

 

me too I get backfire is that bad?
