Everytime I start up the engine, i would hear a rumble from the exhaust, like a v8 mustang with straight pipes... and i got the car about 1 month. The rumble stops after about 10 seconds and Today i decided to take a look under my car, see what could cause that noise. From what i have seen the previous owner removed the muffler and kept the resonator... WHAT AN IDIOT !!!... i said, after reading all the posts about keeping the muffler and cutting the resonator off.
I don't know what to do, I like the sound of it, i am worried about the waranty and I hope it's not gonna be considered void or something.
Has anyone else done this to their car? And also in your opinion is it good or bad?
