alright i have a question for yall with them.... i just have the universal borla muffler, i guess you can say turbo muffler or whatever...what is the sound difference if any in them and the x-r1 cause mine is pretty quit until i mash it thats when everyone can hear me...

 

well actually I had the Borla Turbo muffler for about a total of 2 weeks before i had the xr-1 installed!! A WHOLE lot better... The idle of the XR-1 is louder (mean but not straight sounding), but at 2000 RPM the XR-1 might be a LITTLE louder while cruising but about the same. However when you floor the XR-1 staights come to mind... LOL The turbo not so much haha!!

 

the xr-1 has a very crisp? sound to it. i have it and it sounds badass
