stepped headers vs smooth bore

I talked to bub rep yestreday about pros & cons of bub7 and the brouhard systems. said that the sound was a little louder from 7's, deeper from brouhards. the performance was little better from 7's due to stepped headers. (brouhards are smooth) but couldn't say really how much. (for my setup) . he only had personal experience w/ the 7's. both are excellent choices and I understand that its my choice, but some other users input will be welcome. after all
-information is power- he was helpfull and more was talked about but hell, still dont know which way to go. leaning to the brou. but----- new system will be tds and be bought in about 2 weeks. I need so of your first hand review and evals. my ride is an 07 flhrc, seac, pcIII. and chrome- lots- stock motor for now $$$$$

Macride, the guy "should" have told you the Bub 7 true duals were designed for large displacement high output motors. By large I'm talking 113"+. On a stock motor you'll really loose on the low and mid range.

I did ask that very question and the reply was " not at all, it will work nicely on a stocker" and as I replied I won't be towing a trailer and don't hot rod it I should be good? that is why I'm here

This is my .02...it's your money. I'm stating from what I know from my experience with Bub 7 pipes. Sounds to me like you talked to a sales rep that was bound and determined to sell you a set of pipes. But, like I stated above, this is only .02...

I love the 7's, I run them on my 07SG, stock motor. I found better power than my V&H truedual setup. Just be prepared for noise, they are loud. I switched to the 7 Stealth muff and love it.

I went with the Bub 7s after exhaustive research trying to find the "best" pipe out there for a 124" motor. The numbers are 120/130 respectively. Pipes are probably costing me 10 lbft of tq. I'm a bigger fan of 2-1 but the only one designed two years ago for a big motor was the D&D Boarzilla. I had ran the Boarzilla on a 116" motor for two weeks, I couldn't take the noise.

The Bub 7s do show a flat spot at about 2800 rpm but I can't feel it driving. I'm looking VERY close at the new V&H Hi-po 2-1 but haven't seen numbers from anything larger than a 113" yet.

Any size true duals will adversely effect a stock motor. Optimum would be a good 2-1 like a Supertrapp or D&D Fatcat.
