yeah, if I have another Street Canon baffle fail and it's outside of warranty I may just put the stockers back on instead of spending more..the stockers actually sounded pretty decent for Touring..my Canons perform great and with the tune the torque peaks at 3k so happy with the performance..I don't think I'd have much, if any, drop off there going back to stockers but may have to retune..may even consider knocking out that plug in them since they aren't straight thru..but I don't know..hopefully the Canons will hold up this time so I won't have to do anything

I don't think there's any question the stock pipes would aid in low end. I lost torque with Rinehart 4.5's and no stage 1, for sure. I put stock muffs back. Pretty significant difference. I went ahead with stage 1 and reinstalled Rineharts and regained most of the low end torque on the canned Street Cannons map. I still think the torque hits a "bit" later. I am still contemplating putting stock muffs back on. I loved the LET and actually liked the sound. I don't think I'd need to re-flash or tune. I'm also considering a set of 18 CVO mufflers as well as the Street Cannons.

Supertrapp has tunable mufflers where you add or subtract discs based on what you're looking for; more discs = bigger hole = freer flowing, and they laid out a document to show that fewer discs = quieter and more low-end torque, more discs = louder and more high-end hp.
I wonder if you guys would benefit from those DK Customs Thunder Torque Inserts? They're under $20 and they make some pretty big claims for 'em. Seems like a way to plug up the hole a little and thus increase back pressure some. Might give you some of the torque back that you're missing?

thanks..good report..I'm unwilling to sacrifice any low end tq..spent 1/4 of my life riding and racing 2 strokes so been at the other end of the pendulum..in my mid 50's now and love having the grunt and pull right off idle, and can still wind her up as needed and have not felt compelled to do a Stage II since I haven't really read that it adds much of anything low to what I already have

I also am unwilling to sacrifice any torque loss. The M8 is such a beautifully tuned torque monster its crazy to get caught up in the Harley bug of free flowing mufflers for sake of change. Yet I'm doing it. I've done all the way to ported heads, high CR and displacement bumps on four prior Harley's. It was fun doing it, but I can't say every experience was positive. So yeah, I will sort this out till I get every ft/lb of torque, regardless of muffler that the bike has stock at minimum. That's mostly why I PM'd you asking you to attest to same or improved torque with your Street Cannon Stage 1.

All this talk about low end pull at certain rpm...bla bla bla... My buddy has a 17 with stage II power cam. Will flat run away from a stock 107 and a stage II 110ci. I would say if warranty is important.. Harley cams are worth the money. But a stock 107 is no slouch.

I agree, I am more than happy with my HD Stage 2 torque cam. I loved the 107 and the torque cam is just more of a good thing!

the power cam seems to be a better choice for the 107. Shows great gains. With the 114 motor, the tq cam is the winner. It gives more HP and tq then the power cam. Glad to see a happy comment regarding the power cam though. Seems everyone is doing the tq cam

truth is there's no right or wrong, better this or better that..just depends on what individuals prefer..one guy can blow the doors off his buddy's bike and just loves the rush that gives him, and the buddy might be happier than hell with his performance thinking why use a stick of dynamite when an M80 works great, save money on engine upgrades and subsequent fuel economy, etc...do whatever you think it takes to make your experience as fun and enjoyable as you want
