I posted about this awhile back. Not trying to tell ya what to do,..just offering information.

I have Dooley's on my Nomad,..modified my intake, used a P/commander,..wound up disconnecting it, after some [going rich] problems on a trip. Motorcycle runs fine without it.

I have R/H 2-into1 on my Drifter [1500] stock everything else,...it runs just as good,..maybe just a tad better?

There are several types of boxes you can use. I don't recommend the PC unless you dyno the bike and use that to adjust the map. Other boxes let you screw around with them and adjust to your bike. You will get better performance from a PC with dyno adjusted map - so keep that in mind.

But, to simply be rid of problems introduced from a pipe change... the cobra worked fine for me.

If you change the air intake then you will need a Power Commander. I will say stay away from a Hyper- Charger. It will cause issue with the bike. AnneOakley and I both have hyper-chargers.  They do stick out from the side quite a bit. If you spend a couple hundred and have it dyno'd you'd get a little bit more power with one. If you change the air system you can't go back, with some changes (Hyper- charger is one) Chief is right you should need only the Cobra FI2000.

Well, I needed a box with only the addition of my Big Willys... most of the time you don't need anything. So, I suggest you install them and see. If you get backfires, decel popping etc... you may need to get a box. I got a Cobra FI2000 which did the trick with no adjustment.

Hello,

I just order a set of Roadhouse Dooley's for my 2001 1500 FI.   Roadhouse literature states that no mod's need to be made?  I'm not planning on changing the air intake at this time.  Do I need something like a power commander?   I have no idea about this.  Also, the folks I ordered the pipes from said I didn't. Need new exhaust gasket?   Is that correct?
