hey its all good my car is straight open downpipe now but i got the cherry bomb in the garage and a nice lil magnaflow ready to go on there for project "popo leave me alone" im told it should be really quiet and the spool will sound sick..... will also change how when im on it i can barely hear my blow off because the exhaust is so loud..................... good plan for less than 80 dollars!!!!! props to the cherry bomb users!!!!!
