I'll chime in also. On the 12 RGU I ran Trapp 2:1 for 10 months. Good pipe, no real complaints, tuned by Doc. Later on I switched over to the Fulsac Sport pipe, with Trapp Fat shots on the back. Another good pipe. About 3 months before I sold it I put the 2:1 back on with the old tune for a day or so, it was interesting. Both pipes were smooth with the slight advantage to the Trapp 2:1 under 2500. Seat of the pants dyno, lol. Again just a slight difference. On the current, running the Jackpot 2:1:2 header with CVO muffs with 2" Fulsac cores. The front to back balance seems a little closer with the Jackpot.

It's been said that a decatted factory pipe will run with most aftermarket pipes till 115hp +/-. The limiting factor is the slip ons.
But a good set of slip ons cost $600 +/-
And a 2 into 1 pipe is $750......
So now what do you do? Lol......I'm thinking 2 into 1 and be done!

I bought a used 2 into 1 header with the Nightstick (Supertrapp) muffler and left the cat in place. Since I never typically pull past 4000 even when I'm in a hurry, the added restriction should actually enhance the torque (I hope.) Runs great regardless, and the added heat is not an issue on a '00 1550.

Got my decatted pipe from them. Forgot they repack mufflers. And for $165. Pretty good deal.

Quiet baffle will drop the performance abut 2 to 4 Hp and Trq. Well the full crossover will only show the gains with a motor that is putting out about 125 Hp and Torque or more. So no I don't think you need to get that crossover until you build your motor up.
