I don't have any experience with the Tri-Oval exhaust. But I wanted to tell you to be careful when listening to sound clips of exhaust on the internet. I just got done installing the D&D slip on mufflers on my brothers Vision. And when you listen to sound clips of the D&D exhaust they sound like they are decently loud and have a nice rumble. Even in the video's that I shot the D&D's sound fairly loud and have a nice rumble. But in the real world the D&D's are really quiet. Like just barely louder than the stage 1 pipes. I have RPW's on my XC and they are probably 3 times louder than the D&D's even when I unwrapped the baffle on the D&D's.
I'm not bashing any muffler with this post. I'm just saying to be careful when listening to exhaust clips on the internet. I know they are basically all that you have for reference but in my experience the sound you hear over youtube videos isn't really all that close to the reality of the pipes. Good luck!
