every since i put on my o/r h pipe i can smell some gas coming from the exhaust. my friend also commented on it tonight while talking to him before a basketball game. ive read that with the o/r h i will smell a little but i have also noticed a decrease in mpg. any help? thanks
 
Pull codes and look for an adaptive limit O2 code.

Otherwise, much like buttometers, our stinkometers are not very reliable.

Good luck.

82 - Secondary Air Bypass Circuit Failure
84 - EGR Vacuum Regulator (EVR) Control Circuit Failure
