ok the other day i bought an apexi exhaust. i thought it was the world series but on the tip it says rs racing series. was there ever a racing series. the guys i bought it from said it had the lowest decibel of any exhaust. which i thought was the world series. does anyone know anything about this.

 

The World Sport used to be called the apex RS, so you probably just got an old model of it. Now your exhaust is old school

 

Damn you're lucky! The Apex'i RS is a badass exhaust ... it has one of the most unique exhausts notes I have ever heard. Something about the 'throaty' sound it resonates makes it one of a kind IMO. I have the Apex'i WS (World Sport) cat-back which is nice, but I personally like the RS (which my friend has) a lot better. Congrats

 

thanks i guess i had no clue that they changed the name or just got rid of the rs series. and yeah i like the sound of it alot too. its deep but on a quiet side.
