RE: 2 into 1 system
The Rineharts now come with the 02 ports installed...both pipes. They include pipe plugs in case you don't need them.
If you are interested I have a nearly new set...and when I mean nearly new I mean like 30 or 40 miles kind of new set that I will likely be selling in the near future.
I am just making sure that I can make the D&D Fat cats work on my bike before I part with the Rineys.

RE: 2 into 1 system
I have the Pro Pipe Bp and think nothing short of it ! Performance = awsome , very easy to install , and the sound is very deep and a nice crack when on it !

RE: 2 into 1 system
I am leaning towards the Fat Cat b/c I have read good reviews on them, plus they are a local company here in DFW so they can either tune my bike after the pipes are installed or reccomend a good local tuner. Still not decided 100% though.

RE: 2 into 1 system
Anyone found any good sound files of the fat cats?
I'd hate to commit, then crank up the bike and be missing that rinehart rumble.
That's the only thing about 2 into 1's.. It's a very "different" sound I think.
I'm considering the "lollipop" trick to get a little more low-mid torque going and eleviate the drag-pipe torque-dip. Any feedback? Is it a pain? Looks easy enough.. I actually had some thumb-screw type bolts with a wide "handle" for that purpose, rather than the trouble of welding something up.

RE: 2 into 1 system
I made some lollipops for my bike. I did it for the sound, but was amazed at the increase in power. They are loud as hell, though. As in straight-pipe loud. I would like to figure out a way to get the same deep sound, but toned down a bit.
I made mine using washers and long coupling nuts. I cut a groove in one end of the nuts with a hacksaw, and pounded the washer into the groove. No welding necessary. You may have to cut the nut to the right length, as well. Also, be sure you get a bolt that won't force the washer out of the nut when you bolt it in.
Your results will vary, depending on the diameter of your pipes. If you have a larger diameter, you may need to use a reducer, too. My pipes are 1 5/8" I.D.; I did not need one.
The other option you have is to go buy some Big City Thunder baffles. They are just lollipops inside of sleeves or reducers, depending on the pipes they go into.
Hope that helps.

RE: 2 into 1 system
I was considering keeping the stock rinehart baffles which are very low profile, basically sleeves with louvers and using the lollipop in place of the mounting bolt through the endcap, pipe and baffle.. Then test with a few different angles from parallel to 90 degrees profile with the lollipop. I've also considered trying to increase the profile of the louvers on the baffles also.. Just a little more infront of the airflow.

I am a little new to all this, what is the"lollipop" trick?

.. scroll down to see.
A method of fabricating a washer on the end of a bolt mounted at the end of the exhaust pipe. It's mounted so the washer is inside the pipe, inhibiting the airflow of the exhaust just enough to increase back-pressure.
This is the principle behind big city thunder's "baffles" which are basically reducers with one of these lollipops inside to tune the amount of backflow pressure.
Without knowing the technical aspects of it, but increasing the pressure in a drag pipe can eleviate the typical torque dip associated with free flowing drag pipes.. drag pipes are not designed for low-end torque but mainly high-rpm horsepower.. like dragsters.. Though they do sound great, in pulling hills or low-rpm cruising they can be a hassle if not tuned right.. If I'm pulling out of a turn and roll-on the throttle from too high a gear, it will spit a little bit.. Shift into a lower gear and rev it up and it runs like a scalded dog though.
