thanks for info fellas,
i did put the OEM cat back on and everything is as should be
no more tingling noise, and the exhaust has quieted down a good 15db, it sounds really good,
if i can get ahold of a digital video camera i will record a clip of it so everyone can hear.
only thing i have to do now is find 2 bolts for the cat heat shield *to replace the ones that got broke, u would think they wouldnt rust after 7 years and 120k miles

*
other than that she sounds B U T FULL
on another note i saw some kid riding in front of me earlier with a NASTY sounding exhuast *CAN O BEE"S fo sHO* he kept reving up at me like he was bad ass, so i passed him and let him hear what a real exhaust sounds like
Thermal, so i should shift at 5k RPM then? because i have tried that and i am alot slower than when i rev to 7500 rpm* yes i know REdlinE is at 6900 or so* i mean if im gonna race someone i need to be able to rev out longer, but for cruising i dont shift above 5k anymore.*this is where exhaust note starts to lose the hUMMMM*
thanks again guys.
Daniel
