I added Rush slip-ons to my 2012 Custom, but didn't need to tune. I have a Power Vision, but it's engaged - not married - to my Fatboy S. I might end up tuning with my PV, but I'd have to buy a $200 license.

 

Why, too loud? Good sounding good performing muffs IMO.

Yes 158W TTI's from DK Customs. The 258W quieted down the pipes too much for my liking.

 

wait...didn't I just read your thread about you getting rid of your sporty because of a battery issue with the dealership? Did you change your mind?

A friend of mine had the same kind of issue...bad battery on a new bike but the dealership said it has to stay on the bike to be covered under warranty, but said they can't tow it because they don't have the resources (manpower) to pick it up. what is one to do...new bike that hasn't been ridden in months.

For me, I had warranty on my 2011 but I upgraded everything except the motor and trans since I did not want to void that part of the warranty. I sold the Sporty only because I wanted a Classic Harley...I sometimes regret that decision. IMHO it's not the bike that's faulty, it's the dealership...don't get rid of the bike, get rid of the dealership... of course, not all dealerships are alike. .I feel for you.

LAS VEGAS JIM - sorry did not mean to hijack your thread. Hope you find the pipes of your liking. Here is a thread I created a while back just to help those looking for an exhaust system like you....at least with respect to looks and sound..

Did you do dyno runs to see the difference the TTIs made?

I can't help thinking as this thread keeps bubbling to the top that there is a very large market of pipes that ruin the performance of the engine and DK have swooped in to save the day.

I am no expert and can only go by what I see and read.

 

 

Over here there has been quite a number of new and newish Sportsters with stator wire problems. It rubs on the crankcase and in the first instance it will be an intermittent connection until the wire rubs completely through.

Yes it looks like the battery is faulty but it is not being charged properly whilst the bike is running.

 

Yes but not to test the TTIs. I wanted to compare my powervision tune versus a dyno tune both with TTI's. I used the top two lead techs at the dealership to do the dyno. To the OP, here is a thread I create which will give you some info of what the Powervision can provide with respect to a good tune.

TTI's were butt dyno'd. I've tested (butt dyno'd) all three sizes on these muffs including with no TTIs.. The 158 gave me the best results with respect to sound and performance (low-mid range torque and smoother thru the powerband). The 118W did nothing for the bike...too small. The 258W as stated quieted down the bike more than I like...I also could not turn/angle the TTI's enough to open it up (it hit the baffles).

WIZ - DK Customs I believe has the 258Q the quiet version of the 258W. Not sure what the different is...perhaps Kevin the K in DK can pipe in, but the 258W did quiet down the Rush alot IMO...perhaps the Q will do so even more. The Rush slip-ons are awesome. I would install them in a heartbeat on my shovelhead, but Rush does not manufacturer or offer products older than 86.....a waste to dump them.

 

A friend recommended that I look at Cobra 3" RPT Slip On mufflers (Part #6081). Does anyone have any experience with this muffler or Cobras in general?
