i think thats the way they're engineered... i dont think there's any way to get around it sounding like that unless you pull a completely different engine...

Different mufflers and resonators emit different tones. I would like something louder and deeper than stock, but not raspy or ricey.

This sounds decent...minus the raspy crap at the beginning.

YO Dudes...the race Kia Koup is just like every other pure race car...it sounds like that because...well...basically...IT DOESN"T have an exhaust system! LoL!!! It probably has an open exhaust...no muffler and no resonator.

I like my Kias with their 10 year 100,000 mile powertrain warranty!

I like the sound of this system personally...they could for sure use Roadrace's lightweight pulley for the deceleration issue though.
