Aural upgrade only. There really isn't much difference in performance.

But don't let that stop you! Setting off car alarms is priceless. [clap] [clap]

 

Can't speak to the S4, but when I installed slip-on's, I felt an immediate seat-of-the-pants-gauged thrust gain. I can't verify if it increased peak power or not, but I'm pretty confident that it filled in some "holes" in the power band. Off the line, the bike immediately felt stronger.

 

I definitely felt more power after my slips ons were installed on my 749

 

I noticed a difference but I did slip ones with Filter and ECU.

Maybe it was the sound that though I was going faster =)

Thanks

Well, once I get my new rear shock put on, I'm going to get the MIVV low oval shorts. I'll let you guys know how I make out with them.

 

I saw somewhere where Termi slip-ons made a tiny difference--but cutting the airbox top off made the biggest single difference when looking at "total kit" gains on an S4.

By the way, just got my S4 tuned withe a Power Commander on TOP the the DP ECu+Termi's+spaghetti header+airbox. Gained 2 HP up top--to 110 RWHP; and 4-5 HP in various RPM ranges, most notably in the 3500-45-- range--a good place for more power throttling on out corners, etc.

That was just your mind psychologically compensating for the $600+ you just spent. [laugh]

Seriously, just slip ons don't add any appreciable performance to the bike.

 

I really wasn't expecting any gains...just hopefull. Still want to get better sound out of the thing. Maybe I will even be able to hear it over my clutch ;D

 

if you count hooliganism, and general badassery performance gains, then you'll see A LOT!!
