You need to read a little closer. The Wolf has a removable baffle. With it out it's about as straight and bare as a pipe.
+1 what Cal is saying. Again, reading through my experiences you will find that the stock systems on these bikes are VERY well balanced as they come from the factory and since the Triumph has done their homework it is very difficult for a AM manufacturer to improve on this.
Because it is so well balanced in it's tune, even though lean, any changes one makes will alter this balance and the ECU will need to be remapped to take advantage of this perceived changed improvement. Both in fueling schedule, ignition curve and advance. Without the proper mapping or investing in a TuneBoy/TuneEdit you are just throwing your money away.
Actually, performance does alter quite a bit between baffle in and baffle out though with it in, the can still does what Wolf says it will do but out it's another story and flat exceeded my expectations in performance gains and driveability by a wide margin.
As a newbie one thing to consider is that there are only two or three can manufacturers where installing a can and having it mapped properly will have any real performance gain at all. Noise doesn't = performance and in fact there will be a degradation of performance with most of them.
The reason I held off for so long in getting a can is the Wolf stubbie was the first one that looked promising to me. The ROI for a couple of HP and questionable torque increase wasn't there before. There are other places I can stick $400 and get my performance ROI and have a better outcome.
The real restriction in the air in/air out torque department is really in the airbox. But increasing it's size would only be good at the top end as lower in the real working range it refills itself fine.
As I said in the beginning, Triumph really did their homework as I'm sure other bike manufacturers have done also.
Okay here is where I'm a little confused on this. I thought the real guts and airflow from the exhaust where coming from the header back to the midpipe and even with some packing the silencer/muffler can doesn't restrict airflow that much that it would make that much of drastic change. But, as I said earlier I'm a noob.
I'll take your advice and have it remapped. BTW I did read the link you provided, which I appreciated, however it was on wolf/trident exhausts. Since I'm new to this whole slip on thing I've been told that cans from different mfg. are like apples and oranges.
