Assuming you're discussing the GT. The reality is no slip on will make a sound difference unless you remove the Cat and Res by opting for a full exhaust replacement. Most riders here I believe are using M4 or Brooks. I opted for Yoshimura since I thought the others are 'wake up the neighbors' loud but the Yosh from my experience is a perfect blend of sound and performance. Also as one member here pointed out (which I really like) Suzuki and Yosh is like peanut butter and jelly

With a Full exhaust system replacement (regardless of brand) you will require a retune of the ecu. I recommend the use of the Healtech ESE even though you 'should' be able to tune it out but for some reason on this machine it may still turn on an error code without it.

Good Luck. Kick stands up, rubber side down!

 

Thanks, this is useful. Do you have the Yosh slip-on or the full exhaust replacement? I'm also looking to maybe replacing the OEM exhaust with either an Akra or Yosh.

 

Oh, BTW, the member Horgh (my fan - peanut butter & jelly) has a brand new Healtech ESE for sale which he bought but never used. Hit him up...

 

I appreciate the shoutout and honestly, if I was to do it again, I might get the Yoshi system instead. Don't get me wrong, the M4 sounds great, but I think I'm getting old or something because I'm catching myself thinking it's a bit too loud. The DB insert works well to tame it down a bit, but I would still love to hear the Yoshi system in person sometime, somehow.
