It seems a bit raspy for my taste.
On our exhaust, power seems to come when you get rid of the restrictive downpipe, not the muffler.
If you go for an off road downpipe, suddenly you're going to need that muffler because it will be really loud without it.
If sound is you're thing, go for it.
My philosophy is wait for a system that sounds good and is dyno proven.
The negative to my philosophy is I'm still waiting.
