ok i want a quiet but deep exhaust also, i installed launc control help out >

my setup is a all motor 170 whp d16,

right now i have custom 4-2-1 header-stock cat+2.5" piping-3"tip curved can

im thinking about replacing cat with test pipe and replacing the straight throught muffler with a stock gsr muffler ??

what would be best for launc contorl as it will spit flames, WONT THE BURN MY STOCK cat if i have it ?

 

can i use a cat or no ?

 

you can run a 2 step with or without cat, muffler, exhaust it all depends if your making a track car if it is driving on the street. are you trying to say by removing the cat and putting the stack gsr muffler on you are trying to supress the flames

 

well the 2 step is fule cut controlled , im street car, i just want somethig fun and to launch my car good, but i dont want to run catleass and make my exhaust soud liek **** u know.

 

well then run it with a full exhaust if your shooting flames that means not enough fuel is being combusted so there isnt really much your exhaust is going to change with that

 

get a resonated test pipe
