Any of you tried this pipe yet?  I personally like the look of this pipe out of all the 2-1's for softails but I did not find any info. regarding whether they are a tunable exhaust... I am thinking about dumping my big radius for these in hopes of geting back some torque back in the 2-3000 range.

I attached my Dyno sheet- Big Radius Exhaust... I dont know how much more torque we could get with just an exhaust change....

I have a set sitting in my Garage, waiting to be installed.  

I couldn't get a dyno appt at the dealer until the middle of June, so I'm not sure when they will be installed.  I was thinking about a Thundermax at the same time, but Zippers has no map availiable for the pipes, and Tony recommended going with the SERT instead.  I was also going to do a Zippers A/C, Manifold and Throttle Body at the same time, but am not sure now.  I've been waiting for a week and a half to hear back from Zippers on pricing and needed parts but after 2 phone calls and an E-mail, I am still waiting.  

There is another Tuner I may go check out, he wants to use J.E.T intake manifolds, he's really high on them.  He could get the work done quicker, but I'm a bit concerned about going outside the dealer, in case there is a warranty issue.

Decisions, decisions....

Tunedse2,

I am not getting the same numbers you are with the big radius, but then again my dyno runs are corrected not uncorrected like yours.  I hit 92 lb. ft. torque at 4400 rpm and 92 hp at 5500, all stock except pipes, p-commander and thunder city monster baffles.  I just installed the Zippers 575 cams and got it dynoed Fri.  It put out 102 lb. ft. torque at 4200 rpm and 97 hp at 5500.  While I got significant gains with the cam upgrade, it did not increase my low end torque (2000-3000 range) very much.  My bike stays in the mid 80's for torque until 3500 and them climbs, hence why I am switching to a 2-1.  I have seen enough dyno runs and talked to my dyno run mechanic enough to know that the 2-2's are just not able to create enough resonance wave to get that good low end snap I want.  Mine should be here Thu. and I'm heading for the dyno for a tune shortly thereafter.

Big City Thunder Baffle did wonders for my 2:2 Rineharts, brought the bottom end back like the stock pipe, and man they sound great in a Rinehart

Mbegalla, are you saying you used the Big City  Thunder Baffles in your 2:2 Rineharts? And was that on a 103 FatBoy? And were they staggerds or  straights?

Ok now what kind of change in sound and decible leval did you experience with the Big City Thunder Baffles?

[mbegalla]

no, I used them on my 2006 FHLTCUSE , IT LOWERED, OR DEEPENED THE SOUND A BIT, NOT MUCH, BUT A LITTLE, I THINK IT SOUNDS BETTER, AND MY BOTTOM END POWER CAME BACK, THESE WHERE THE NEWER STYLE 2/2 RINEHARTS THAT I USED

I didn't have a CVO but on my Fatboy I ran the D&D 2 into 1 and they were just right
Great looks and the noise level didn't over power you on long trips
The stage 1 was all I had and the low end torq was something I really appreciated with the 2 into 1's
