Ok, so far I've gotten four exhaust tickets, so I went with the ITR muffler. It's quiet and the flow is better tahn the DX ones. Any running their turbo with an oem stock muffler? Any negative side effects of running stock muffler and 3" exhaust piping?? Keep in mind I don't want to get stopped for having loud exhaust and turbo. Any information is appreciated. A friend on mine told me I can blow my motor. Now i'm a bit concerned...

 

i dont beleave it could be as bad as blowing a motor but i do beleave the motor would lose power do to back pressure but thats about it i would recomend the thermal turbo muffler its not super loud but its a 3"
