i drive a ek with a d15b motor and i want to get a straight pipe with bigger pipings because i am going to buy a turbo kit pretty soon. what kind of resonator and muffler should i buy? im not tryin to attract too many cops or set off other car alarms . please HELP

 

1.5l with a basic turbo can definitely breath with a mandrel 2.5 system.

And get a muffler and resonator if you don't want to set off car alarms.
