Hi all. I'm sure that this subject has been bashed to death in other columns but I'm just seeking a little input. I have a 2010 FXDC with harley slip-ons, stage 1 air kit and factory download for the fuel injection. I want to go with a full exhaust that favors real-world low and midrange gains and is not too terribly loud. Would a 2 into 1 or dual system be the better way to go? Thanks in advance, take care.

 

I think the basic thing is this, a 2 into 1 will give you a better gain in TQ, and honestly probably a deeper sound. Some people prefer the way 2 - 2 look. Ive always heard Thunderheader gives the most power gain. I saw Rush has a new 2 - 1 full system that looks good, and Im sure would sound awesome. Lots of choices. Bassani also has nice
looking 2 - 1

 

I can't speak for other 2-1 systems but the Thunderheader isn't terribly loud until you twist that throttle. Nice bark to my ears.

 

I like my BUB 7 2 into 1's! Not too loud until crank open the throttle!

 

i always liked the look of 2 into 2 system,, then i jumped onto the 2 into 1 bandwagon,, took alittle time to get used to the look,,, now i think it looks sharp on the bike and really like the roar when you twist the throttle,,, if you decide to go for it you wont regret it

 

I have D&D Fatcats, very pleased with the look, sound and performance!

 

Maybe looking at some dyno sheets might help, since most of the time people post their respective setups.

Go w/the 2-1 for reasons listed...D&D FatCat or V&H ProPipe are two great choices - good luck!

 

I have the V&H Big Radius 2 into 1 and LOVE IT
