Ok please forgive my kinda stupid question. I just put on my apexi gt spec exhaust a few weeks ago. I havent driven the car but about 10 miles if that. Today i took it around the block a few times and when i got out i touched the muffler to see how warm it was. I heard rotories run hotter than most cars. my muffler was REALLY hot. Is that normal/ thanks

 

both my s4 exhaust sytems have been really hot , apexi n1 with a hks down pipe on my first , and a freeflowin n1 style on my current,the current one gets so hot it warps the bumper but is nothin i would worry about. oh an btw a ford explorer cat's o2 sensor looks for a temp around 650 degrees c never touch an exhaust system

 

A non-turbo rotary engine usually runs an EGT around 1650-1700F. Don't touch the exhaust system when it is hot! Also, be careful not to park over flammable things like leaves or tall dried grass.

the muffler not the DP or cats. just the muffler. I know better than to touch any piping near the motor

 

dang that sounds crazy dangerous lol.

 

my muffler is discolored goldish/brown from the heat.

 

On my wrx my HKS Hi-Power melted my bumber. Catless full turbo back. So Imagine on a rx7....
