If the OP's question is about power gains, nothing better than a 2-1 exhaust that's properly stepped.
Personally, I've never cared for their pipes, I think their fugly but that's just my opinion. IH is correct about the warranty however, the dealer is stepping up to take the fall in case something goes wrong, not the moco.

Default I had the TBR on my 17SG

My SG was only a Stg1 so no comparison to OPs' motor. I loved the sound (loud as hell when your on it).
Here is a pic and a small clip(raise your speaker volume for the clip).

Great looking bike! The sound sure fits it. Thanks!

Older thread but now with tax returns...
Gotta ask; have you added a cam yet? If so, Any dip in early torque from the limited back pressure from the short pipe? I had the Comp-S on my heritage 114 and had no complaints, but I want to do a 475 or a 22x cam with plate & pump and heard the shorter pipes make the M8 finicky with a torque cam. Last question, at cruising speed RPMs 2k-3200 does it interfere with hearing your music? Never needed to know with the Softail, but now with the 107 street glide I gotta ask

Sorry to say I don't own the bike anymore. No problem listening the radio/sound at those rpm's except when your on it, at that point i had bigger things to concentrate on. But no, enjoying the stereo was not a problem at lower rpms. Didn't get a chance to add a cam.

However, you're not going to get squat if that was tuned with a Pro Street Tuner, because there are no tunes available for non-Harley pipes, and if it was tuned with any other tuner, the powertrain warranty is already void.
I think what the OP was saying is that the subject pipe isn't a full-length 2:1 where the pipe extends past the saddlebag like your Pro Pipe did.

Strychnine on a 2 into 1 for max grunt/power the merge has to be as close as possible to parallel any merge where the pipes point towards each other is wasting energy.

If you want power all the way through the rpm range a "good" 2 into 1 will deliver more low end and midrange torque. That's what baggers love. True duals or a short 2 into 1 will kill low end and mid range, but produce the most top end horsepower. The problem is....How much time do you spend running at 4500 rpms and over? There's a reason the D&D 2 into 1 is so popular with performance minded guys. The Thunderheader, V&H, J&B, and other 2 into 1 pipes all have long primaries into a collector and are known to work. For that reason I have no interest in that TBR pipe.
