Yeah, the exhaust note has changed a bit, 1) because you can hear it down the right hand side more, and 2) i think it sounds a bit different because of how the right hand tips are made. It's just a simple "Y" piece so it has changed the note slightly because of how they made it. Would probably be better if that first tip was slightly rounded, but i think the time and effort to do that probably isn't worth the money? who knows
So you see how it's made to distribute the airflow to both tips so it doesn't all just rush the the far right one, and so it actually makes the exhaust burble a bit more. It's hard to explain lol, I'll have to get an audio clip soon.
Oh and now i have tips on both sides, it's close to impossible to get up my driveway without something scraping
There is a fine crack above the right hand tips already where they have pushed hard into the bar. I mean, the tips probably hang about 15 to 20mm below the bar, and i've managed to scrape the bar too, so it's forced the exhaust up around 20mm where there is no 20mm to fit.
