Introduction
Finally I have assembled the Greasehouse Grunt slip-on Exhaust. Being lazy, I got it fitted from a roadside mechanic and soon realised just how easy it is to just remove the original can and fit this new one. All you need is a set of allen key and spanners to change the exhaust in 30 minutes flat.
Aesthetics
The exhaust looks premium and it blends in well with the overall look of the KTM Duke 390. The side mounted can, makes the bike look fuller and gives it a more purposeful stance. As mentioned in the first report, its premium quality and finish make the bike look more expensive and a lot of people take notice. The exhaust, however, fits really close to the swing arm and it remains to be seen whether it will touch if one of the screws come loose.
The sound
It is loud! To the bare ears I am not sure it will be street legal too. But Greasehouse also supplies a DB killer to soften it down. Although, that defeats the whole point of putting an aftermarket exhaust in the first place. If you are a flamboyant person and like your bikes loud, then this is the exhaust for you. The good thing is that, it doesn’t sound trashy unless you red-line the engine where it starts shrieking which can get a bit irritating over long rides. At low to medium revs, this exhaust has a nice bassy note. It pops and bangs on the overrun too and the Grunt slip-on exhaust definitely adds more character to an already hooligan bike.
Conclusion
In the final part of the review on this exhaust, we will test it on our Vbox to see if Greasehouse’s claims of performance gains are true and if it’s really worth spending Rs 15,000 on this high quality slip-on.
