Looked at their website, says the 2x2 only fits stock or Bassani slip ons, also says uses the stock crossover pipe, is that correct?

 

This headpipe will mount any slip-ons that mounts to a stock headpipe. Right side is larger than the left. Yes, use stock x-over.

 

I decatted it without cutting and welding. It took me about 2 hours, long drill bits and a long chisel. For the slip ones, I used B&E Super Flow slip ons. They take stock mufflers, gut them and install new packing and baffles (I used 1 3/4"). I think the mufflers were about $165, the rest was sweat equity! I know it's running cooler now.

 

I went the same way as HD Fan but mated my Bassani headers to a pair of 4 inch Rineharts and did the cam at the same time so only needed one dyno tune.......sounds fn awesome and goes like a rocket now.......97 HP / 109 ft/lbs TQ.

The Bassani website has a few errors for the product but as above these headers fit any muffler that will mate to the stock headers. It does use the stock cross over tube but there is a "power chamber" near the junction that better equalises flow to both mufflers compared to stock setup.

 

My 2017 sg with stage 3 114 stock header with Vance and Hines HO slip ons dyno 111 hp with 118 tq the header pipe is going south I think I’m gonna use jack pot but not sure changing cams and heads I’m hoping for a lot more .

 

 

I like my Thundercones!

 

Well, I dropped some coin on mine. I figured I'm going to have this bike a while and wanted it set up right the first time. At first I bought the V&H OS450 and immediately noticed I lost bottom end and the sound was horrible, not to mention a vibration that came on at 2800 rpms. V&H refunded my money and I did a ton of research. I ended up with Fuel Moto Jackpot 2-1-2 Header and S&S MK45s, plus the Woods WM8-22X Camshaft. Let me tell you, it's a completely different bike and it's a beast. Best yet, it's a sleeper. Love it and have no regrets!!

 

I edited my post because it was an old thread I had nothing new to add.
